Java8-291之后 , 禁用了TLS1.1 , 使JDBC无法用SSL连接SqlServer2008怎么办,以下是解决办法
修改java.security文件
1.找到jre的java.security文件
如果是jre , 在 {JAVA_HOME} / jre / lib / security中, 比如????
C:Program FilesJavajre1.8.0_301libsecurity
如果是Eclipse绿色免安装便携版
在安装文件夹搜索java.security ,比如????
xxxpluginsorg.eclipse.justj.openjdk.hotspot.jre.full.win32.x86_64_16.0.1.v20210528-1205jreconfsecurity
如果是window下的安装版Eclipse
文件在c:/用户文件夹/.p2/pool/plugins/…中, 例如????
C:Usersadmin.p2poolpluginsorg.eclipse.justj.openjdk.hotspot.jre.full.win32.x86_64_16.0.2.v20210721-1149jreconfsecurity
如果在C盘搜索java.security,可能搜出两个以上,temp文件夹中也有
2.打开java.security并搜索 “jdk.tls.disabledAlgorithms=”
jdk.tls.disabledAlgorithms=
可找到????
# Example: # jdk.tls.disabledAlgorithms=MD5, SSLv3, DSA, RSA keySize < 2048, # rsa_pkcs1_sha1, secp224r1 jdk.tls.disabledAlgorithms=SSLv3, TLSv1, TLSv1.1, RC4, DES, MD5withRSA, DH keySize < 1024, EC keySize < 224, 3DES_EDE_CBC, anon, NULL
3.删掉TLSv1, TLSv1.1,
删掉后变为????
# Example: # jdk.tls.disabledAlgorithms=MD5, SSLv3, DSA, RSA keySize < 2048, # rsa_pkcs1_sha1, secp224r1 jdk.tls.disabledAlgorithms=SSLv3, RC4, DES, MD5withRSA, DH keySize < 1024, EC keySize < 224, 3DES_EDE_CBC, anon, NULL
4.保存,可以了
修改后的样例,jre8可直接复制

# This is the "master security properties file".
#
# An alternate java.security properties file may be specified
# from the command line via the system property
#
# -Djava.security.properties=<URL>
#
# This properties file appends to the master security properties file.
# If both properties files specify values for the same key, the value
# from the command-line properties file is selected, as it is the last
# one loaded.
#
# Also, if you specify
#
# -Djava.security.properties==<URL> (2 equals),
#
# then that properties file completely overrides the master security
# properties file.
#
# To disable the ability to specify an additional properties file from
# the command line, set the key security.overridePropertiesFile
# to false in the master security properties file. It is set to true
# by default.
# In this file, various security properties are set for use by
# java.security classes. This is where users can statically register
# Cryptography Package Providers ("providers" for short). The term
# "provider" refers to a package or set of packages that supply a
# concrete implementation of a subset of the cryptography aspects of
# the Java Security API. A provider may, for example, implement one or
# more digital signature algorithms or message digest algorithms.
#
# Each provider must implement a subclass of the Provider class.
# To register a provider in this master security properties file,
# specify the provider and priority in the format
#
# security.provider.<n>=<provName | className>
#
# This declares a provider, and specifies its preference
# order n. The preference order is the order in which providers are
# searched for requested algorithms (when no specific provider is
# requested). The order is 1-based; 1 is the most preferred, followed
# by 2, and so on.
#
# <provName> must specify the name of the Provider as passed to its super
# class java.security.Provider constructor. This is for providers loaded
# through the ServiceLoader mechanism.
#
# <className> must specify the subclass of the Provider class whose
# constructor sets the values of various properties that are required
# for the Java Security API to look up the algorithms or other
# facilities implemented by the provider. This is for providers loaded
# through classpath.
#
# Note: Providers can be dynamically registered instead by calls to
# either the addProvider or insertProviderAt method in the Security
# class.
#
# List of providers and their preference orders (see above):

# A list of preferred providers for specific algorithms. These providers will
# be searched for matching algorithms before the list of registered providers.
# Entries containing errors (parsing, etc) will be ignored. Use the
# -Djava.security.debug=jca property to debug these errors.
#
# The property is a comma-separated list of serviceType.algorithm:provider
# entries. The serviceType (example: "MessageDigest") is optional, and if
# not specified, the algorithm applies to all service types that support it.
# The algorithm is the standard algorithm name or transformation.
# Transformations can be specified in their full standard name
# (ex: AES/CBC/PKCS5Padding), or as partial matches (ex: AES, AES/CBC).
# The provider is the name of the provider. Any provider that does not
# also appear in the registered list will be ignored.
#
# There is a special serviceType for this property only to group a set of
# algorithms together. The type is "Group" and is followed by an algorithm
# keyword. Groups are to simplify and lessen the entries on the property
# line. Current groups are:
# Group.SHA2 = SHA-224, SHA-256, SHA-384, SHA-512, SHA-512/224, SHA-512/256
# Group.HmacSHA2 = HmacSHA224, HmacSHA256, HmacSHA384, HmacSHA512
# Group.SHA2RSA = SHA224withRSA, SHA256withRSA, SHA384withRSA, SHA512withRSA
# Group.SHA2DSA = SHA224withDSA, SHA256withDSA, SHA384withDSA, SHA512withDSA
# Group.SHA2ECDSA = SHA224withECDSA, SHA256withECDSA, SHA384withECDSA,

# Sun Provider SecureRandom seed source.
#
# Select the primary source of seed data for the "NativePRNG", "SHA1PRNG"
# and "DRBG" SecureRandom implementations in the "Sun" provider.
# (Other SecureRandom implementations might also use this property.)
#
# On Unix-like systems (for example, Linux/MacOS), the
# "NativePRNG", "SHA1PRNG" and "DRBG" implementations obtains seed data from
# special device files such as file:/dev/random.
#
# On Windows systems, specifying the URLs "file:/dev/random" or
# "file:/dev/urandom" will enable the native Microsoft CryptoAPI seeding
# mechanism for SHA1PRNG and DRBG.
#
# By default, an attempt is made to use the entropy gathering device
# specified by the "securerandom.source" Security property. If an
# exception occurs while accessing the specified URL:
#
# NativePRNG:
# a default value of /dev/random will be used. If neither
# are available, the implementation will be disabled.
# "file" is the only currently supported protocol type.
#
# SHA1PRNG and DRBG:
# the traditional system/thread activity algorithm will be used.
#
# The entropy gathering device can also be specified with the System
# property "java.security.egd". For example:
#
# % java -Djava.security.egd=file:/dev/random MainClass
#
# Specifying this System property will override the
# "securerandom.source" Security property.
#
# In addition, if "file:/dev/random" or "file:/dev/urandom" is
# specified, the "NativePRNG" implementation will be more preferred than
# DRBG and SHA1PRNG in the Sun provider.

# in the SUN provider. (Other DRBG implementations can also use this property.)
# Applications can request different instantiation parameters like security
# strength, capability, personalization string using one of the
# getInstance(...,SecureRandomParameters,...) methods with a
# DrbgParameters.Instantiation argument, but other settings such as the
# mechanism and DRBG algorithm names are not currently configurable by any API.

# Properties to configure OCSP for certificate revocation checking
#
# Enable OCSP
#
# By default, OCSP is not used for certificate revocation checking.
# This property enables the use of OCSP when set to the value "true".
#
# NOTE: SocketPermission is required to connect to an OCSP responder.
#
# Example,
# ocsp.enable=true
#
# Location of the OCSP responder
#
# By default, the location of the OCSP responder is determined implicitly
# from the certificate being validated. This property explicitly specifies
# the location of the OCSP responder. The property is used when the
# Authority Information Access extension (defined in RFC 5280) is absent
# from the certificate or when it requires overriding.
#
# Example,
# ocsp.responderURL=http://ocsp.example.net:80
#
# Subject name of the OCSP responder's certificate
#
# By default, the certificate of the OCSP responder is that of the issuer
# of the certificate being validated. This property identifies the certificate
# of the OCSP responder when the default does not apply. Its value is a string
# distinguished name (defined in RFC 2253) which identifies a certificate in
# the set of certificates supplied during cert path validation. In cases where
# the subject name alone is not sufficient to uniquely identify the certificate
# then both the "ocsp.responderCertIssuerName" and
# "ocsp.responderCertSerialNumber" properties must be used instead. When this
# property is set then those two properties are ignored.
#
# Example,
# ocsp.responderCertSubjectName=CN=OCSP Responder, O=XYZ Corp
#
# Issuer name of the OCSP responder's certificate
#
# By default, the certificate of the OCSP responder is that of the issuer
# of the certificate being validated. This property identifies the certificate
# of the OCSP responder when the default does not apply. Its value is a string
# distinguished name (defined in RFC 2253) which identifies a certificate in
# the set of certificates supplied during cert path validation. When this
# property is set then the "ocsp.responderCertSerialNumber" property must also
# be set. When the "ocsp.responderCertSubjectName" property is set then this
# property is ignored.
#
# Example,
# ocsp.responderCertIssuerName=CN=Enterprise CA, O=XYZ Corp
#
# Serial number of the OCSP responder's certificate
#
# By default, the certificate of the OCSP responder is that of the issuer
# of the certificate being validated. This property identifies the certificate
# of the OCSP responder when the default does not apply. Its value is a string
# of hexadecimal digits (colon or space separators may be present) which
# identifies a certificate in the set of certificates supplied during cert path
# validation. When this property is set then the "ocsp.responderCertIssuerName"
# property must also be set. When the "ocsp.responderCertSubjectName" property
# is set then this property is ignored.
#
# Example,
# ocsp.responderCertSerialNumber=2A:FF:00
#
# Policy for failed Kerberos KDC lookups:
#
# When a KDC is unavailable (network error, service failure, etc), it is
# put inside a blacklist and accessed less often for future requests. The
# value (case-insensitive) for this policy can be:
#
# tryLast
# KDCs in the blacklist are always tried after those not on the list.
#
# tryLess[:max_retries,timeout]
# KDCs in the blacklist are still tried by their order in the configuration,
# but with smaller max_retries and timeout values. max_retries and timeout
# are optional numerical parameters (default 1 and 5000, which means once
# and 5 seconds). Please notes that if any of the values defined here is
# more than what is defined in krb5.conf, it will be ignored.
#
# Whenever a KDC is detected as available, it is removed from the blacklist.
# The blacklist is reset when krb5.conf is reloaded. You can add
# refreshKrb5Config=true to a JAAS configuration file so that krb5.conf is
# reloaded whenever a JAAS authentication is attempted.
#
# Example,
# krb5.kdc.bad.policy = tryLast
# krb5.kdc.bad.policy = tryLess:2,2000
#
krb5.kdc.bad.policy = tryLast
#
# Kerberos cross-realm referrals (RFC 6806)
#
# OpenJDK's Kerberos client supports cross-realm referrals as defined in
# RFC 6806. This allows to setup more dynamic environments in which clients
# do not need to know in advance how to reach the realm of a target principal
# (either a user or service).
#
# When a client issues an AS or a TGS request, the "canonicalize" option
# is set to announce support of this feature. A KDC server may fulfill the
# request or reply referring the client to a different one. If referred,
# the client will issue a new request and the cycle repeats.
#
# In addition to referrals, the "canonicalize" option allows the KDC server
# to change the client name in response to an AS request. For security reasons,
# RFC 6806 (section 11) FAST scheme is enforced.
#
# Disable Kerberos cross-realm referrals. Value may be overwritten with a
# System property (-Dsun.security.krb5.disableReferrals).
sun.security.krb5.disableReferrals=false
# Maximum number of AS or TGS referrals to avoid infinite loops. Value may

# This property contains a list of disabled EC Named Curves that can be included

#
# Algorithm restrictions for certification path (CertPath) processing
#
# In some environments, certain algorithms or key lengths may be undesirable
# for certification path building and validation. For example, "MD2" is
# generally no longer considered to be a secure hash algorithm. This section
# describes the mechanism for disabling algorithms based on algorithm name
# and/or key length. This includes algorithms used in certificates, as well
# as revocation information such as CRLs and signed OCSP Responses.
# The syntax of the disabled algorithm string is described as follows:
# DisabledAlgorithms:
# " DisabledAlgorithm { , DisabledAlgorithm } "
#
# DisabledAlgorithm:
# AlgorithmName [Constraint] { '&' Constraint } | IncludeProperty
#
# AlgorithmName:
# (see below)
#
# Constraint:
# KeySizeConstraint | CAConstraint | DenyAfterConstraint |
# UsageConstraint
#
# KeySizeConstraint:
# keySize Operator KeyLength
#
# Operator:
# <= | < | == | != | >= | >
#
# KeyLength:
# Integer value of the algorithm's key length in bits
#
# CAConstraint:
# jdkCA
#
# DenyAfterConstraint:
# denyAfter YYYY-MM-DD
#
# UsageConstraint:
# usage [TLSServer] [TLSClient] [SignedJAR]
#
# IncludeProperty:
# include <security property>
#
# The "AlgorithmName" is the standard algorithm name of the disabled
# algorithm. See the Java Security Standard Algorithm Names Specification
# for information about Standard Algorithm Names. Matching is
# performed using a case-insensitive sub-element matching rule. (For
# example, in "SHA1withECDSA" the sub-elements are "SHA1" for hashing and
# "ECDSA" for signatures.) If the assertion "AlgorithmName" is a
# sub-element of the certificate algorithm name, the algorithm will be
# rejected during certification path building and validation. For example,
# the assertion algorithm name "DSA" will disable all certificate algorithms
# that rely on DSA, such as NONEwithDSA, SHA1withDSA. However, the assertion
# will not disable algorithms related to "ECDSA".
#
# The "IncludeProperty" allows a implementation-defined security property that
# can be included in the disabledAlgorithms properties. These properties are
# to help manage common actions easier across multiple disabledAlgorithm
# properties.
# There is one defined security property: jdk.disabled.NamedCurves
# See the property for more specific details.
#
#
# A "Constraint" defines restrictions on the keys and/or certificates for
# a specified AlgorithmName:
#
# KeySizeConstraint:
# keySize Operator KeyLength
# The constraint requires a key of a valid size range if the
# "AlgorithmName" is of a key algorithm. The "KeyLength" indicates
# the key size specified in number of bits. For example,
# "RSA keySize <= 1024" indicates that any RSA key with key size less
# than or equal to 1024 bits should be disabled, and
# "RSA keySize < 1024, RSA keySize > 2048" indicates that any RSA key
# with key size less than 1024 or greater than 2048 should be disabled.
# This constraint is only used on algorithms that have a key size.
#
# CAConstraint:
# jdkCA
# This constraint prohibits the specified algorithm only if the
# algorithm is used in a certificate chain that terminates at a marked
# trust anchor in the lib/security/cacerts keystore. If the jdkCA
# constraint is not set, then all chains using the specified algorithm
# are restricted. jdkCA may only be used once in a DisabledAlgorithm
# expression.
# Example: To apply this constraint to SHA-1 certificates, include
# the following: "SHA1 jdkCA"
#
# DenyAfterConstraint:
# denyAfter YYYY-MM-DD
# This constraint prohibits a certificate with the specified algorithm
# from being used after the date regardless of the certificate's
# validity. JAR files that are signed and timestamped before the
# constraint date with certificates containing the disabled algorithm
# will not be restricted. The date is processed in the UTC timezone.
# This constraint can only be used once in a DisabledAlgorithm
# expression.
# Example: To deny usage of RSA 2048 bit certificates after Feb 3 2020,
# use the following: "RSA keySize == 2048 & denyAfter 2020-02-03"
#
# UsageConstraint:
# usage [TLSServer] [TLSClient] [SignedJAR]
# This constraint prohibits the specified algorithm for
# a specified usage. This should be used when disabling an algorithm
# for all usages is not practical. 'TLSServer' restricts the algorithm
# in TLS server certificate chains when server authentication is
# performed. 'TLSClient' restricts the algorithm in TLS client
# certificate chains when client authentication is performed.
# 'SignedJAR' constrains use of certificates in signed jar files.
# The usage type follows the keyword and more than one usage type can
# be specified with a whitespace delimiter.
# Example: "SHA1 usage TLSServer TLSClient"
#
# When an algorithm must satisfy more than one constraint, it must be
# delimited by an ampersand '&'. For example, to restrict certificates in a
# chain that terminate at a distribution provided trust anchor and contain
# RSA keys that are less than or equal to 1024 bits, add the following
# constraint: "RSA keySize <= 1024 & jdkCA".
#
# All DisabledAlgorithms expressions are processed in the order defined in the
# property. This requires lower keysize constraints to be specified
# before larger keysize constraints of the same algorithm. For example:
# "RSA keySize < 1024 & jdkCA, RSA keySize < 2048".
#
# Note: The algorithm restrictions do not apply to trust anchors or
# self-signed certificates.
#
# Note: This property is currently used by Oracle's PKIX implementation. It
# is not guaranteed to be examined and used by other implementations.
#
# Example:
# jdk.certpath.disabledAlgorithms=MD2, DSA, RSA keySize < 2048
#
#
jdk.certpath.disabledAlgorithms=MD2, MD5, SHA1 jdkCA & usage TLSServer,
RSA keySize < 1024, DSA keySize < 1024, EC keySize < 224
#
# Legacy algorithms for certification path (CertPath) processing and
# signed JAR files.
#
# In some environments, a certain algorithm or key length may be undesirable
# but is not yet disabled.
#
# Tools such as keytool and jarsigner may emit warnings when these legacy
# algorithms are used. See the man pages for those tools for more information.
#
# The syntax is the same as the "jdk.certpath.disabledAlgorithms" and
# "jdk.jar.disabledAlgorithms" security properties.
#
# Note: This property is currently used by the JDK Reference
# implementation. It is not guaranteed to be examined and used by other
# implementations.

# for signed JAR validation. For example, "MD2" is generally no longer
# considered to be a secure hash algorithm. This section describes the
# mechanism for disabling algorithms based on algorithm name and/or key length.
# JARs signed with any of the disabled algorithms or key sizes will be treated
# as unsigned.
#
# The syntax of the disabled algorithm string is described as follows:
# DisabledAlgorithms:
# " DisabledAlgorithm { , DisabledAlgorithm } "
#
# DisabledAlgorithm:
# AlgorithmName [Constraint] { '&' Constraint }
#
# AlgorithmName:
# (see below)
#
# Constraint:
# KeySizeConstraint | DenyAfterConstraint
#
# KeySizeConstraint:
# keySize Operator KeyLength
#
# DenyAfterConstraint:
# denyAfter YYYY-MM-DD
#
# Operator:
# <= | < | == | != | >= | >
#
# KeyLength:
# Integer value of the algorithm's key length in bits
#
# Note: This property is currently used by the JDK Reference
# implementation. It is not guaranteed to be examined and used by other
# implementations.
#
# See "jdk.certpath.disabledAlgorithms" for syntax descriptions.

#
# Algorithm restrictions for Secure Socket Layer/Transport Layer Security
# (SSL/TLS/DTLS) processing
#
# In some environments, certain algorithms or key lengths may be undesirable
# when using SSL/TLS/DTLS. This section describes the mechanism for disabling
# algorithms during SSL/TLS/DTLS security parameters negotiation, including
# protocol version negotiation, cipher suites selection, named groups
# selection, signature schemes selection, peer authentication and key
# exchange mechanisms.
#
# Disabled algorithms will not be negotiated for SSL/TLS connections, even
# if they are enabled explicitly in an application.
#
# For PKI-based peer authentication and key exchange mechanisms, this list
# of disabled algorithms will also be checked during certification path
# building and validation, including algorithms used in certificates, as
# well as revocation information such as CRLs and signed OCSP Responses.
# This is in addition to the jdk.certpath.disabledAlgorithms property above.
#
# See the specification of "jdk.certpath.disabledAlgorithms" for the
# syntax of the disabled algorithm string.
#
# Note: The algorithm restrictions do not apply to trust anchors or
# self-signed certificates.
#
# Note: This property is currently used by the JDK Reference implementation.
# It is not guaranteed to be examined and used by other implementations.
#
# Example:
# jdk.tls.disabledAlgorithms=MD5, SSLv3, DSA, RSA keySize < 2048,
# rsa_pkcs1_sha1, secp224r1
jdk.tls.disabledAlgorithms=SSLv3, RC4, DES, MD5withRSA,
DH keySize < 1024, EC keySize < 224, 3DES_EDE_CBC, anon, NULL
#
# Legacy algorithms for Secure Socket Layer/Transport Layer Security (SSL/TLS)
# processing in JSSE implementation.
#
# In some environments, a certain algorithm may be undesirable but it
# cannot be disabled because of its use in legacy applications. Legacy
# algorithms may still be supported, but applications should not use them
# as the security strength of legacy algorithms are usually not strong enough
# in practice.
#
# During SSL/TLS security parameters negotiation, legacy algorithms will
# not be negotiated unless there are no other candidates.
#
# The syntax of the legacy algorithms string is described as this Java
# BNF-style:
# LegacyAlgorithms:
# " LegacyAlgorithm { , LegacyAlgorithm } "
#
# LegacyAlgorithm:
# AlgorithmName (standard JSSE algorithm name)
#
# See the specification of security property "jdk.certpath.disabledAlgorithms"
# for the syntax and description of the "AlgorithmName" notation.
#
# Per SSL/TLS specifications, cipher suites have the form:
# SSL_KeyExchangeAlg_WITH_CipherAlg_MacAlg
# or
# TLS_KeyExchangeAlg_WITH_CipherAlg_MacAlg
#
# For example, the cipher suite TLS_RSA_WITH_AES_128_CBC_SHA uses RSA as the
# key exchange algorithm, AES_128_CBC (128 bits AES cipher algorithm in CBC
# mode) as the cipher (encryption) algorithm, and SHA-1 as the message digest
# algorithm for HMAC.
#
# The LegacyAlgorithm can be one of the following standard algorithm names:
# 1. JSSE cipher suite name, e.g., TLS_RSA_WITH_AES_128_CBC_SHA
# 2. JSSE key exchange algorithm name, e.g., RSA
# 3. JSSE cipher (encryption) algorithm name, e.g., AES_128_CBC
# 4. JSSE message digest algorithm name, e.g., SHA
#
# See SSL/TLS specifications and the Java Security Standard Algorithm Names
# Specification for information about the algorithm names.
#
# Note: If a legacy algorithm is also restricted through the
# jdk.tls.disabledAlgorithms property or the
# java.security.AlgorithmConstraints API (See
# javax.net.ssl.SSLParameters.setAlgorithmConstraints()),
# then the algorithm is completely disabled and will not be negotiated.
#
# Note: This property is currently used by the JDK Reference implementation.
# It is not guaranteed to be examined and used by other implementations.
# There is no guarantee the property will continue to exist or be of the
# same syntax in future releases.
#
# Example:
# jdk.tls.legacyAlgorithms=DH_anon, DES_CBC, SSL_RSA_WITH_RC4_128_MD5
#
jdk.tls.legacyAlgorithms=NULL, anon, RC4, DES, 3DES_EDE_CBC
#
# The pre-defined default finite field Diffie-Hellman ephemeral (DHE)
# parameters for Transport Layer Security (SSL/TLS/DTLS) processing.
#
# In traditional SSL/TLS/DTLS connections where finite field DHE parameters
# negotiation mechanism is not used, the server offers the client group
# parameters, base generator g and prime modulus p, for DHE key exchange.
# It is recommended to use dynamic group parameters. This property defines
# a mechanism that allows you to specify custom group parameters.
#
# The syntax of this property string is described as this Java BNF-style:
# DefaultDHEParameters:
# DefinedDHEParameters { , DefinedDHEParameters }
#
# DefinedDHEParameters:
# "{" DHEPrimeModulus , DHEBaseGenerator "}"
#
# DHEPrimeModulus:
# HexadecimalDigits
#
# DHEBaseGenerator:
# HexadecimalDigits
#
# HexadecimalDigits:
# HexadecimalDigit { HexadecimalDigit }
#
# HexadecimalDigit: one of
# 0 1 2 3 4 5 6 7 8 9 A B C D E F a b c d e f
#
# Whitespace characters are ignored.
#
# The "DefinedDHEParameters" defines the custom group parameters, prime
# modulus p and base generator g, for a particular size of prime modulus p.
# The "DHEPrimeModulus" defines the hexadecimal prime modulus p, and the
# "DHEBaseGenerator" defines the hexadecimal base generator g of a group
# parameter. It is recommended to use safe primes for the custom group
# parameters.
#
# If this property is not defined or the value is empty, the underlying JSSE
# provider's default group parameter is used for each connection.
#
# If the property value does not follow the grammar, or a particular group
# parameter is not valid, the connection will fall back and use the
# underlying JSSE provider's default group parameter.
#
# Note: This property is currently used by OpenJDK's JSSE implementation. It
# is not guaranteed to be examined and used by other implementations.
#
# Example:
# jdk.tls.server.defaultDHEParameters=
# {

# TLS key limits on symmetric cryptographic algorithms
#
# This security property sets limits on algorithms key usage in TLS 1.3.
# When the amount of data encrypted exceeds the algorithm value listed below,
# a KeyUpdate message will trigger a key change. This is for symmetric ciphers
# with TLS 1.3 only.
#
# The syntax for the property is described below:
# KeyLimits:
# " KeyLimit { , KeyLimit } "
#
# WeakKeyLimit:
# AlgorithmName Action Length
#
# AlgorithmName:
# A full algorithm transformation.
#
# Action:
# KeyUpdate
#
# Length:
# The amount of encrypted data in a session before the Action occurs
# This value may be an integer value in bytes, or as a power of two, 2^29.
#
# KeyUpdate:
# The TLS 1.3 KeyUpdate handshake process begins when the Length amount
# is fulfilled.
#
# Note: This property is currently used by OpenJDK's JSSE implementation. It
# is not guaranteed to be examined and used by other implementations.

# Cryptographic Jurisdiction Policy defaults
#
# Import and export control rules on cryptographic software vary from
# country to country. By default, Java provides two different sets of
# cryptographic policy files[1]:
#
# unlimited: These policy files contain no restrictions on cryptographic
# strengths or algorithms
#
# limited: These policy files contain more restricted cryptographic
# strengths
#
# The default setting is determined by the value of the "crypto.policy"
# Security property below. If your country or usage requires the
# traditional restrictive policy, the "limited" Java cryptographic
# policy is still available and may be appropriate for your environment.
#
# If you have restrictions that do not fit either use case mentioned
# above, Java provides the capability to customize these policy files.
# The "crypto.policy" security property points to a subdirectory
# within <java-home>/conf/security/policy/ which can be customized.
# Please see the <java-home>/conf/security/policy/README.txt file or consult
# the Java Security Guide/JCA documentation for more information.
#
# YOU ARE ADVISED TO CONSULT YOUR EXPORT/IMPORT CONTROL COUNSEL OR ATTORNEY
# TO DETERMINE THE EXACT REQUIREMENTS.
#
# [1] Please note that the JCE for Java SE, including the JCE framework,
# cryptographic policy files, and standard JCE providers provided with
# the Java SE, have been reviewed and approved for export as mass market

# Serialization system-wide filter
#
# A filter, if configured, is used by java.io.ObjectInputStream during
# deserialization to check the contents of the stream.
# A filter is configured as a sequence of patterns, each pattern is either
# matched against the name of a class in the stream or defines a limit.
# Patterns are separated by ";" (semicolon).
# Whitespace is significant and is considered part of the pattern.
#
# If the system property jdk.serialFilter is also specified, it supersedes
# the security property value defined here.
#
# If a pattern includes a "=", it sets a limit.
# If a limit appears more than once the last value is used.
# Limits are checked before classes regardless of the order in the
# sequence of patterns.
# If any of the limits are exceeded, the filter status is REJECTED.
#
# maxdepth=value - the maximum depth of a graph
# maxrefs=value - the maximum number of internal references
# maxbytes=value - the maximum number of bytes in the input stream
# maxarray=value - the maximum array length allowed
#
# Other patterns, from left to right, match the class or package name as
# returned from Class.getName.
# If the class is an array type, the class or package to be matched is the
# element type.
# Arrays of any number of dimensions are treated the same as the element type.
# For example, a pattern of "!example.Foo", rejects creation of any instance or
# array of example.Foo.
