4632N/A# This is the "master security properties file".
4632N/A# In this file, various security properties are set for use by
4632N/A# Cryptography Package Providers ("providers" for short). The term
4632N/A# "provider" refers to a package or set of packages that supply a
4632N/A# concrete implementation of a subset of the cryptography aspects of
4632N/A# the Java Security API. A provider may, for example, implement one or
4632N/A# more digital signature algorithms or message digest algorithms.
4632N/A# Each provider must implement a subclass of the Provider class.
4632N/A# To register a provider in this master security properties file,
4632N/A# specify the Provider subclass name and priority in the format
4632N/A# This declares a provider, and specifies its preference
4632N/A# order n. The preference order is the order in which providers are
4632N/A# searched for requested algorithms (when no specific provider is
4632N/A# requested). The order is 1-based; 1 is the most preferred, followed
4632N/A# <className> must specify the subclass of the Provider class whose
4632N/A# constructor sets the values of various properties that are required
4632N/A# for the Java Security API to look up the algorithms or other
4632N/A# facilities implemented by the provider.
4632N/A# There is a default provider that comes standard with the JDK. It
4632N/A# is called the "SUN" provider, and its Provider subclass
4632N/A# "SUN" provider is registered via the following:
4632N/A# (The number 1 is used for the default provider.)
4632N/A# Note: Providers can be dynamically registered instead by calls to
4632N/A# either the addProvider or insertProviderAt method in the Security
4632N/A# List of providers and their preference orders (see above):
4632N/A# Select the source of seed data for SecureRandom. By default an
4632N/A# attempt is made to use the entropy gathering device specified by
4632N/A# exists, a special SecureRandom implementation is activated by default.

4632N/A# that will be used as the Policy object.
4632N/A# The default is to have a single system-wide policy file,
4632N/A# and a policy file in the user's home directory.
4632N/A# whether or not we expand properties in the policy file
4632N/A# if this is set to false, properties (${...}) will not be expanded in policy
4632N/A# whether or not we allow an extra policy to be passed on the command line
4632N/A# whether or not we look into the IdentityScope for trusted Identities
4632N/A# when encountering a 1.1 signed JAR file. If the identity is found
4632N/A# and is trusted, we grant it AllPermission.

4632N/A# The Java-level namelookup cache policy for successful lookups:
4632N/A# any negative value: caching forever
4632N/A# any positive value: the number of seconds to cache an address for
4632N/A# default value is forever (FOREVER). For security reasons, this
4632N/A# caching is made forever when a security manager is set. When a security
4632N/A# manager is not set, the default behavior in this implementation
4632N/A# is to cache for 30 seconds.
4632N/A# NOTE: setting this to anything other than the default value can have
4632N/A# serious security implications. Do not set it unless
4632N/A# you are sure you are not exposed to DNS spoofing attack.
4632N/A# The Java-level namelookup cache policy for failed lookups:
4632N/A# any negative value: cache forever
4632N/A# any positive value: the number of seconds to cache negative lookup results
4632N/A# In some Microsoft Windows networking environments that employ
4632N/A# the WINS name service in addition to DNS, name service lookups
4632N/A# that fail may take a noticeably long time to return (approx. 5 seconds).
4632N/A# For this reason the default caching policy is to maintain these
4632N/A# Properties to configure OCSP for certificate revocation checking
4632N/A# By default, OCSP is not used for certificate revocation checking.
4632N/A# This property enables the use of OCSP when set to the value "true".
4632N/A# NOTE: SocketPermission is required to connect to an OCSP responder.
4632N/A# Location of the OCSP responder
4632N/A# By default, the location of the OCSP responder is determined implicitly
4632N/A# from the certificate being validated. This property explicitly specifies
4632N/A# the location of the OCSP responder. The property is used when the
4632N/A# Authority Information Access extension (defined in RFC 3280) is absent
4632N/A# from the certificate or when it requires overriding.
4632N/A# Subject name of the OCSP responder's certificate
4632N/A# By default, the certificate of the OCSP responder is that of the issuer
4632N/A# of the certificate being validated. This property identifies the certificate
4632N/A# of the OCSP responder when the default does not apply. Its value is a string
4632N/A# distinguished name (defined in RFC 2253) which identifies a certificate in
4632N/A# the set of certificates supplied during cert path validation. In cases where
4632N/A# the subject name alone is not sufficient to uniquely identify the certificate
4632N/A# property is set then those two properties are ignored.
4632N/A# Issuer name of the OCSP responder's certificate
4632N/A# By default, the certificate of the OCSP responder is that of the issuer
4632N/A# of the certificate being validated. This property identifies the certificate
4632N/A# of the OCSP responder when the default does not apply. Its value is a string
4632N/A# distinguished name (defined in RFC 2253) which identifies a certificate in
4632N/A# the set of certificates supplied during cert path validation. When this
4632N/A# Serial number of the OCSP responder's certificate
4632N/A# By default, the certificate of the OCSP responder is that of the issuer
4632N/A# of the certificate being validated. This property identifies the certificate
4632N/A# of the OCSP responder when the default does not apply. Its value is a string
4632N/A# of hexadecimal digits (colon or space separators may be present) which
4632N/A# identifies a certificate in the set of certificates supplied during cert path
4632N/A# is set then this property is ignored.
4632N/A# Policy for failed Kerberos KDC lookups:
4632N/A# When a KDC is unavailable (network error, service failure, etc), it is
4632N/A# put inside a blacklist and accessed less often for future requests. The
4632N/A# value (case-insensitive) for this policy can be:
4632N/A# KDCs in the blacklist are always tried after those not on the list.
4632N/A# tryLess[:max_retries,timeout]
4632N/A# KDCs in the blacklist are still tried by their order in the configuration,
4632N/A# but with smaller max_retries and timeout values. max_retries and timeout
4632N/A# are optional numerical parameters (default 1 and 5000, which means once
4632N/A# and 5 seconds). Please notes that if any of the values defined here is
4632N/A# Whenever a KDC is detected as available, it is removed from the blacklist.
4632N/A# refreshKrb5Config=true to a JAAS configuration file so that
krb5.conf is
4632N/A# reloaded whenever a JAAS authentication is attempted.
4632N/A# Algorithm restrictions for certification path (CertPath) processing
4632N/A# In some environments, certain algorithms or key lengths may be undesirable
4632N/A# for certification path building and validation. For example, "MD2" is
4632N/A# generally no longer considered to be a secure hash algorithm. This section
4632N/A# describes the mechanism for disabling algorithms based on algorithm name
4632N/A#
and/or key length. This includes algorithms used in certificates, as well
4632N/A# as revocation information such as CRLs and signed OCSP Responses.
4632N/A# The syntax of the disabled algorithm string is described as this Java
4632N/A# " DisabledAlgorithm { , DisabledAlgorithm } "
4632N/A# AlgorithmName [Constraint]
4632N/A# keySize Operator DecimalInteger
4632N/A# DecimalDigit {DecimalDigit}
4632N/A# The "AlgorithmName" is the standard algorithm name of the disabled
4632N/A# algorithm. See "Java Cryptography Architecture Standard Algorithm Name
4632N/A# Documentation" for information about Standard Algorithm Names. Matching
4632N/A# is performed using a case-insensitive sub-element matching rule. (For
4632N/A# example, in "SHA1withECDSA" the sub-elements are "SHA1" for hashing and
4632N/A# "ECDSA" for signatures.) If the assertion "AlgorithmName" is a
4632N/A# sub-element of the certificate algorithm name, the algorithm will be
4632N/A# rejected during certification path building and validation. For example,
4632N/A# the assertion algorithm name "DSA" will disable all certificate algorithms
4632N/A# that rely on DSA, such as NONEwithDSA, SHA1withDSA. However, the assertion
4632N/A# will not disable algorithms related to "ECDSA".
4632N/A# A "Constraint" provides further guidance for the algorithm being specified.
4632N/A# The "KeySizeConstraint" requires a key of a valid size range if the
4632N/A# "AlgorithmName" is of a key algorithm. The "DecimalInteger" indicates the
4632N/A# key size specified in number of bits. For example, "RSA keySize <= 1024"
4632N/A# indicates that any RSA key with key size less than or equal to 1024 bits
4632N/A# should be disabled, and "RSA keySize < 1024, RSA keySize > 2048" indicates
4632N/A# that any RSA key with key size less than 1024 or greater than 2048 should
4632N/A# be disabled. Note that the "KeySizeConstraint" only makes sense to key
4632N/A# Note: This property is currently used by Oracle's PKIX implementation. It
4632N/A# is not guaranteed to be examined and used by other implementations.
4632N/A# In some environments, certain algorithms or key lengths may be undesirable
4632N/A# when using
SSL/TLS. This section describes the mechanism for disabling
4632N/A# algorithms during
SSL/TLS security parameters negotiation, including cipher
4632N/A# suites selection, peer authentication and key exchange mechanisms.
4632N/A# For PKI-based peer authentication and key exchange mechanisms, this list
4632N/A# of disabled algorithms will also be checked during certification path
4632N/A# building and validation, including algorithms used in certificates, as
4632N/A# well as revocation information such as CRLs and signed OCSP Responses.
