# 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 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.
#
# List of providers and their preference orders (see above):
#
security.provider.1=sun.security.provider.Sun
security.provider.2=sun.security.rsa.SunRsaSign
security.provider.3=sun.security.ec.SunEC
security.provider.4=com.sun.net.ssl.internal.ssl.Provider
security.provider.5=com.sun.crypto.provider.SunJCE
security.provider.6=sun.security.jgss.SunProvider

# Sun Provider SecureRandom seed source.
#
# 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
# specified, the "NativePRNG" implementation will be more preferred than
# SHA1PRNG in the Sun provider.

#
# 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 3280) 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
# 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 } "
#
# DisabledAlgorithm:
# AlgorithmName [Constraint]
#
# AlgorithmName:
# (see below)
#
# Constraint:
# KeySizeConstraint
#
# KeySizeConstraint:
# keySize Operator DecimalInteger
#
# Operator:
# <= | < | == | != | >= | >
#
# DecimalInteger:
# DecimalDigits
#
# DecimalDigits:
# DecimalDigit {DecimalDigit}
#
# DecimalDigit: one of
# 1 2 3 4 5 6 7 8 9 0
#
# The "AlgorithmName" is the standard algorithm name of the disabled
# 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
# be disabled. Note that the "KeySizeConstraint" only makes sense to key
# algorithms.
#
# 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, RSA keySize < 1024
# Algorithm restrictions for Secure Socket Layer/Transport Layer Security
# (SSL/TLS) processing
#
# In some environments, certain algorithms or key lengths may be undesirable
# when using SSL/TLS. This section describes the mechanism for disabling
# algorithms during SSL/TLS security parameters negotiation, including cipher
# suites selection, peer authentication and key exchange mechanisms.
#
# 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: This property is currently used by Oracle's JSSE implementation.
# It is not guaranteed to be examined and used by other implementations.
#
# Example:
# jdk.tls.disabledAlgorithms=MD5, SHA1, DSA, RSA keySize < 2048
