# 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

#
|
|
# 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

|
|
# 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 subclass name and priority in the format
|
|
#
|
|
# security.provider.<n>=<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.
|
|
#
|
|
# <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.
|
|
#
|
|
# There must be at least one provider specification in java.security.
|
|
# There is a default provider that comes standard with the JDK. It
|
|
# is called the "SUN" provider, and its Provider subclass
|
|
# named Sun appears in the sun.security.provider package. Thus, the
|
|
# "SUN" provider is registered via the following:
|
|
#
|
|
# security.provider.1=sun.security.provider.Sun
|
|
#
|
|
# (The number 1 is used for the default provider.)
|
|
#
|
|
# Note: Providers can be dynamically registered instead by calls to
|
|
# either the addProvider or insertProviderAt method in the Security
|
|
# class.

# Select the primary source of seed data for the "SHA1PRNG" and
|
|
# "NativePRNG" SecureRandom implementations in the "Sun" provider.
|
|
# (Other SecureRandom implementations might also use this property.)
|
|
#
|
|
# On Unix-like systems (for example, Solaris/Linux/MacOS), the
|
|
# "NativePRNG" and "SHA1PRNG" 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.
|
|
#
|
|
# 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:
|
|
#
|
|
# SHA1PRNG:
|
|
# the traditional system/thread activity algorithm will be used.
|
|
#
|
|
# 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.
|
|
#
|
|
# 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

# Location of the OCSP responder
|
|
#
|
|
# By default, the location of the OCSP responder is determined implicitly

# the location of the OCSP responder. The property is used when the
|
|
# Authority Information Access extension (defined in RFC 3280) is absent
|
|
# from the certificate or when it requires overriding.

|
# 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

|
# 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

|
|
# 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

# 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 this Java
|
|
# BNF-style:
|
|
# DisabledAlgorithms:
|
|
# " DisabledAlgorithm { , DisabledAlgorithm } "
|

|
# algorithm. See "Java Cryptography Architecture Standard Algorithm Name
|
|
# Documentation" 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".
|
|
#
|
|
# A "Constraint" provides further guidance for the algorithm being specified.
|
|
# The "KeySizeConstraint" requires a key of a valid size range if the
|
|
# "AlgorithmName" is of a key algorithm. The "DecimalInteger" 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

|
|
#
|
|
# 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 disabled algorithm string is described as this Java
|
|
# BNF-style:
|
|
# LegacyAlgorithms:

# LegacyAlgorithm:

# 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 "Java Cryptography Architecture Standard
|
