# # 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 security.provider.7=com.sun.security.sasl.Provider security.provider.8=org.jcp.xml.dsig.internal.dom.XMLDSigRI security.provider.9=sun.security.smartcardio.SunPCSC # # 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".

This property explicitly specifies # the location of the OCSP responder.

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.

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 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 "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". # # 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.

By default, the JDK provides two different sets of # cryptographic policy files: # # unlimited: These policy files contain no restrictions on cryptographic # strengths or algorithms. # # limited: These policy files contain more restricted cryptographic # strengths, and are still available if your country or # usage requires the traditional restrictive policy. # # The JDK JCE framework uses the unlimited policy files by default. # However the user may explicitly choose a set either by defining the # "crypto.policy" Security property or by installing valid JCE policy # jar files into the traditional JDK installation location. To better # support older JDK Update releases, the "crypto.policy" property is not # defined by default. See below for more information. # # The following logic determines which policy files are used: # # <java-home> refers to the directory where the JRE was # installed and may be determined using the "java.home" # System property. # # 1. If the Security property "crypto.policy" has been defined, # then the following mechanism is used: # # The policy files are stored as jar files in subdirectories of # <java-home>/lib/security/policy. Each directory contains a complete # set of policy files. # # The "crypto.policy" Security property controls the directory # selection, and thus the effective cryptographic policy. # # The default set of directories is: # # limited | unlimited # # 2. If the "crypto.policy" property is not set and the traditional # US_export_policy.jar and local_policy.jar files # (e.g. limited/unlimited) are found in the legacy # <java-home>/lib/security directory, then the rules embedded within # those jar files will be used. This helps preserve compatibility # for users upgrading from an older installation. # # 3. If the jar files are not present in the legacy location # and the "crypto.policy" Security property is not defined, # then the JDK will use the unlimited settings (equivalent to # crypto.policy=unlimited) # # Please see the JCA documentation for additional information on these # files and formats. # # YOU ARE ADVISED TO CONSULT YOUR EXPORT/IMPORT CONTROL COUNSEL OR ATTORNEY # TO DETERMINE THE EXACT REQUIREMENTS. # # 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 # encryption item by the US Bureau of Industry and Security. # # Note: This property is currently used by the JDK Reference implementation. # It is not guaranteed to be examined and used by other implementations. # crypto.policy=unlimited # # The policy for the XML Signature secure validation mode.
