16#    -Djava.security.properties==<URL> (2 equals),
17#
18# then that properties file completely overrides the master security

20#
21# To disable the ability to specify an additional properties file from
22# the command line, set the key security.overridePropertiesFile
23# to false in the master security properties file. It is set to true
24# by default.
25#
26# If this properties file fails to load, the JDK implementation will throw
27# an unspecified error when initializing the java.security.Security class.
28# Properties in this file are typically parsed only once. If any of the
29# properties are modified, applications should be restarted to ensure the
30# changes are properly reflected.

32# In this file, various security properties are set for use by
33# java.security classes. This is where users can statically register
34# Cryptography Package Providers ("providers" for short). The term
35# "provider" refers to a package or set of packages that supply a
36# concrete implementation of a subset of the cryptography aspects of
37# the Java Security API. A provider may, for example, implement one or
38# more digital signature algorithms or message digest algorithms.
39#
40# Each provider must implement a subclass of the Provider class.
41# To register a provider in this master security properties file,
42# specify the provider and priority in the format
43#
44#    security.provider.<n>=<provName | className>
45#
46# This declares a provider, and specifies its preference
47# order n. The preference order is the order in which providers are
48# searched for requested algorithms (when no specific provider is
49# requested). The order is 1-based; 1 is the most preferred, followed
50# by 2, and so on.
51#
52# <provName> must specify the name of the Provider as passed to its super
53# class java.security.Provider constructor. This is for providers loaded
54# through the ServiceLoader mechanism.
55#
56# <className> must specify the subclass of the Provider class whose
57# constructor sets the values of various properties that are required
58# for the Java Security API to look up the algorithms or other
59# facilities implemented by the provider. This is for providers loaded
60# through classpath.
61#
62# Note: Providers can be dynamically registered instead by calls to
63# either the addProvider or insertProviderAt method in the Security
64# class.

86# Entries containing errors (parsing, etc) will be ignored. Use the
87# -Djava.security.debug=jca property to debug these errors.
88#
89# The property is a comma-separated list of serviceType.algorithm:provider
90# entries. The serviceType (example: "MessageDigest") is optional, and if
91# not specified, the algorithm applies to all service types that support it.
92# The algorithm is the standard algorithm name or transformation.
93# Transformations can be specified in their full standard name
94# (ex: AES/CBC/PKCS5Padding), or as partial matches (ex: AES, AES/CBC).
95# The provider is the name of the provider. Any provider that does not
96# also appear in the registered list will be ignored.
97#
98# There is a special serviceType for this property only to group a set of
99# algorithms together. The type is "Group" and is followed by an algorithm
100# keyword. Groups are to simplify and lessen the entries on the property
101# line. Current groups are:
102#   Group.SHA2 = SHA-224, SHA-256, SHA-384, SHA-512, SHA-512/224, SHA-512/256
103#   Group.HmacSHA2 = HmacSHA224, HmacSHA256, HmacSHA384, HmacSHA512
104#   Group.SHA2RSA = SHA224withRSA, SHA256withRSA, SHA384withRSA, SHA512withRSA
105#   Group.SHA2DSA = SHA224withDSA, SHA256withDSA, SHA384withDSA, SHA512withDSA
106#   Group.SHA2ECDSA = SHA224withECDSA, SHA256withECDSA, SHA384withECDSA, \

122# and "DRBG" SecureRandom implementations in the "Sun" provider.
123# (Other SecureRandom implementations might also use this property.)
124#
125# On Unix-like systems (for example, Linux/MacOS), the
126# "NativePRNG", "SHA1PRNG" and "DRBG" implementations obtains seed data from
127# special device files such as file:/dev/random.
128#
129# On Windows systems, specifying the URLs "file:/dev/random" or
130# "file:/dev/urandom" will enable the native Microsoft CryptoAPI seeding
131# mechanism for SHA1PRNG and DRBG.
132#
133# By default, an attempt is made to use the entropy gathering device
134# specified by the "securerandom.source" Security property.  If an
135# exception occurs while accessing the specified URL:
136#
137#     NativePRNG:
138#         a default value of /dev/random will be used.  If neither
139#         are available, the implementation will be disabled.
140#         "file" is the only currently supported protocol type.
141#
142#     SHA1PRNG and DRBG:
143#         the traditional system/thread activity algorithm will be used.
144#
145# The entropy gathering device can also be specified with the System
146# property "java.security.egd". For example:
147#
148#   % java -Djava.security.egd=file:/dev/random MainClass
149#
150# Specifying this System property will override the
151# "securerandom.source" Security property.
152#
153# In addition, if "file:/dev/random" or "file:/dev/urandom" is
154# specified, the "NativePRNG" implementation will be more preferred than
155# DRBG and SHA1PRNG in the Sun provider.

427# property is ignored.
428#
429# Example,
430#   ocsp.responderCertIssuerName=CN=Enterprise CA, O=XYZ Corp

432#
433# Serial number of the OCSP responder's certificate
434#
435# By default, the certificate of the OCSP responder is that of the issuer

437# of the OCSP responder when the default does not apply. Its value is a string
438# of hexadecimal digits (colon or space separators may be present) which
439# identifies a certificate in the set of certificates supplied during cert path
440# validation. When this property is set then the "ocsp.responderCertIssuerName"
441# property must also be set. When the "ocsp.responderCertSubjectName" property

453#
454# tryLast
455#    KDCs in the secondary list are always tried after those not on the list.
456#
457# tryLess[:max_retries,timeout]
458#    KDCs in the secondary list are still tried by their order in the
459#    configuration, but with smaller max_retries and timeout values.
460#    max_retries and timeout are optional numerical parameters (default 1 and
461#    5000, which means once and 5 seconds). Please note that if any of the
462#    values defined here are more than what is defined in krb5.conf, it will be
463#    ignored.
464#
465# Whenever a KDC is detected as available, it is removed from the secondary
466# list. The secondary list is reset when krb5.conf is reloaded. You can add
467# refreshKrb5Config=true to a JAAS configuration file so that krb5.conf is
468# reloaded whenever a JAAS authentication is attempted.
469#
470# Example,

477# Kerberos cross-realm referrals (RFC 6806)

481# do not need to know in advance how to reach the realm of a target principal
482# (either a user or service).
483#
484# When a client issues an AS or a TGS request, the "canonicalize" option
485# is set to announce support of this feature. A KDC server may fulfill the
486# request or reply referring the client to a different one. If referred,
487# the client will issue a new request and the cycle repeats.
488#
489# In addition to referrals, the "canonicalize" option allows the KDC server
490# to change the client name in response to an AS request. For security reasons,
491# RFC 6806 (section 11) FAST scheme is enforced.

551#
552# The "AlgorithmName" is the standard algorithm name of the disabled
553# algorithm. See the Java Security Standard Algorithm Names Specification
554# for information about Standard Algorithm Names.  Matching is
555# performed using a case-insensitive sub-element matching rule.  (For
556# example, in "SHA1withECDSA" the sub-elements are "SHA1" for hashing and
557# "ECDSA" for signatures.)  If the assertion "AlgorithmName" is a
558# sub-element of the certificate algorithm name, the algorithm will be
559# rejected during certification path building and validation.  For example,
560# the assertion algorithm name "DSA" will disable all certificate algorithms
561# that rely on DSA, such as NONEwithDSA, SHA1withDSA.  However, the assertion
562# will not disable algorithms related to "ECDSA".
563#
564# The "IncludeProperty" allows a implementation-defined security property that
565# can be included in the disabledAlgorithms properties.  These properties are
566# to help manage common actions easier across multiple disabledAlgorithm
567# properties.
568# There is one defined security property:  jdk.disabled.namedCurves
569# See the property for more specific details.
570#
571#
572# A "Constraint" defines restrictions on the keys and/or certificates for
573# a specified AlgorithmName:
574#
575#   KeySizeConstraint:
576#     keySize Operator KeyLength
577#       The constraint requires a key of a valid size range if the
578#       "AlgorithmName" is of a key algorithm.  The "KeyLength" indicates
579#       the key size specified in number of bits.  For example,
580#       "RSA keySize <= 1024" indicates that any RSA key with key size less
581#       than or equal to 1024 bits should be disabled, and
582#       "RSA keySize < 1024, RSA keySize > 2048" indicates that any RSA key
583#       with key size less than 1024 or greater than 2048 should be disabled.
584#       This constraint is only used on algorithms that have a key size.
585#
586#   CAConstraint:
587#     jdkCA
588#       This constraint prohibits the specified algorithm only if the
589#       algorithm is used in a certificate chain that terminates at a marked
590#       trust anchor in the lib/security/cacerts keystore.  If the jdkCA
591#       constraint is not set, then all chains using the specified algorithm
592#       are restricted.  jdkCA may only be used once in a DisabledAlgorithm
593#       expression.
594#       Example:  To apply this constraint to SHA-1 certificates, include
595#       the following:  "SHA1 jdkCA"
596#
597#   DenyAfterConstraint:
598#     denyAfter YYYY-MM-DD
599#       This constraint prohibits a certificate with the specified algorithm
600#       from being used after the date regardless of the certificate's
601#       validity.  JAR files that are signed and timestamped before the
602#       constraint date with certificates containing the disabled algorithm
603#       will not be restricted.  The date is processed in the UTC timezone.
604#       This constraint can only be used once in a DisabledAlgorithm
605#       expression.
606#       Example:  To deny usage of RSA 2048 bit certificates after Feb 3 2020,
607#       use the following:  "RSA keySize == 2048 & denyAfter 2020-02-03"
608#
609#   UsageConstraint:
610#     usage [TLSServer] [TLSClient] [SignedJAR]
611#       This constraint prohibits the specified algorithm for
612#       a specified usage.  This should be used when disabling an algorithm
613#       for all usages is not practical. 'TLSServer' restricts the algorithm
614#       in TLS server certificate chains when server authentication is
615#       performed. 'TLSClient' restricts the algorithm in TLS client
616#       certificate chains when client authentication is performed.
617#       'SignedJAR' constrains use of certificates in signed jar files.
618#       The usage type follows the keyword and more than one usage type can
619#       be specified with a whitespace delimiter.
620#       Example:  "SHA1 usage TLSServer TLSClient"
621#
622# When an algorithm must satisfy more than one constraint, it must be
623# delimited by an ampersand '&'.  For example, to restrict certificates in a
624# chain that terminate at a distribution provided trust anchor and contain
625# RSA keys that are less than or equal to 1024 bits, add the following
626# constraint:  "RSA keySize <= 1024 & jdkCA".
627#
628# All DisabledAlgorithms expressions are processed in the order defined in the
629# property.  This requires lower keysize constraints to be specified
630# before larger keysize constraints of the same algorithm.  For example:
631# "RSA keySize < 1024 & jdkCA, RSA keySize < 2048".
632#
633# Note: The algorithm restrictions do not apply to trust anchors or
634# self-signed certificates.
635#
636# Note: This property is currently used by Oracle's PKIX implementation. It
637# is not guaranteed to be examined and used by other implementations.
638#
639# Example:

726# algorithms during SSL/TLS/DTLS security parameters negotiation, including
727# protocol version negotiation, cipher suites selection, named groups

729# exchange mechanisms.
730#
731# Disabled algorithms will not be negotiated for SSL/TLS connections, even
732# if they are enabled explicitly in an application.
733#
734# For PKI-based peer authentication and key exchange mechanisms, this list
735# of disabled algorithms will also be checked during certification path
736# building and validation, including algorithms used in certificates, as
737# well as revocation information such as CRLs and signed OCSP Responses.
738# This is in addition to the jdk.certpath.disabledAlgorithms property above.
739#
740# See the specification of "jdk.certpath.disabledAlgorithms" for the

759#
760# In some environments, a certain algorithm may be undesirable but it
761# cannot be disabled because of its use in legacy applications.  Legacy
762# algorithms may still be supported, but applications should not use them
763# as the security strength of legacy algorithms are usually not strong enough
764# in practice.
765#
766# During SSL/TLS security parameters negotiation, legacy algorithms will
767# not be negotiated unless there are no other candidates.
768#
769# The syntax of the legacy algorithms string is described as this Java
770# BNF-style:
771#   LegacyAlgorithms:
772#       " LegacyAlgorithm { , LegacyAlgorithm } "

777# See the specification of security property "jdk.certpath.disabledAlgorithms"
778# for the syntax and description of the "AlgorithmName" notation.
779#
780# Per SSL/TLS specifications, cipher suites have the form:
781#       SSL_KeyExchangeAlg_WITH_CipherAlg_MacAlg
782# or
783#       TLS_KeyExchangeAlg_WITH_CipherAlg_MacAlg
784#
785# For example, the cipher suite TLS_RSA_WITH_AES_128_CBC_SHA uses RSA as the
786# key exchange algorithm, AES_128_CBC (128 bits AES cipher algorithm in CBC
787# mode) as the cipher (encryption) algorithm, and SHA-1 as the message digest
788# algorithm for HMAC.
789#
790# The LegacyAlgorithm can be one of the following standard algorithm names:
791#     1. JSSE cipher suite name, e.g., TLS_RSA_WITH_AES_128_CBC_SHA
792#     2. JSSE key exchange algorithm name, e.g., RSA
793#     3. JSSE cipher (encryption) algorithm name, e.g., AES_128_CBC
794#     4. JSSE message digest algorithm name, e.g., SHA
795#
796# See SSL/TLS specifications and the Java Security Standard Algorithm Names
797# Specification for information about the algorithm names.
798#
799# Note: If a legacy algorithm is also restricted through the
800# jdk.tls.disabledAlgorithms property or the
801# java.security.AlgorithmConstraints API (See
802# javax.net.ssl.SSLParameters.setAlgorithmConstraints()),
803# then the algorithm is completely disabled and will not be negotiated.

1026#
1027# A filter factory class name is used to configure the JVM-wide filter factory.
1028# The class must be public, must have a public zero-argument constructor, implement the
1029# java.util.function.BinaryOperator<java.io.ObjectInputFilter> interface, provide its
1030# implementation and be accessible via the application class loader.
1031# A builtin filter factory is used if no filter factory is defined.

1040# Deserialization JVM-wide filter
1041#
1042# A filter, if configured, is used by the filter factory to provide the filter used by
1043# java.io.ObjectInputStream during deserialization to check the contents of the stream.
1044# A filter is configured as a sequence of patterns, each pattern is either
1045# matched against the name of a class in the stream or defines a limit.
1046# Patterns are separated by ";" (semicolon).
1047# Whitespace is significant and is considered part of the pattern.
1048#
1049# If the system property jdk.serialFilter is also specified, it supersedes
1050# the security property value defined here.
1051#
1052# If a pattern includes a "=", it sets a limit.
1053# If a limit appears more than once the last value is used.
1054# Limits are checked before classes regardless of the order in the
1055# sequence of patterns.
1056# If any of the limits are exceeded, the filter status is REJECTED.
1057#
1058#   maxdepth=value - the maximum depth of a graph
1059#   maxrefs=value  - the maximum number of internal references
1060#   maxbytes=value - the maximum number of bytes in the input stream
1061#   maxarray=value - the maximum array length allowed
1062#
1063# Other patterns, from left to right, match the class or package name as
1064# returned from Class.getName.
1065# If the class is an array type, the class or package to be matched is the
1066# element type.
1067# Arrays of any number of dimensions are treated the same as the element type.
1068# For example, a pattern of "!example.Foo", rejects creation of any instance or
1069# array of example.Foo.
1070#
1071# If the pattern starts with "!", the status is REJECTED if the remaining
1072# pattern is matched; otherwise the status is ALLOWED if the pattern matches.
1073# If the pattern contains "/", the non-empty prefix up to the "/" is the
1074# module name;
1075#   if the module name matches the module name of the class then
1076#   the remaining pattern is matched with the class name.
1077#   If there is no "/", the module name is not compared.
1078# If the pattern ends with ".**" it matches any class in the package and all
1079# subpackages.
1080# If the pattern ends with ".*" it matches any class in the package.
1081# If the pattern ends with "*", it matches any class with the pattern as a

1169# PKCS12 KeyStore properties
1170#
1171# The following properties, if configured, are used by the PKCS12 KeyStore
1172# implementation during the creation of a new keystore. Several of the
1173# properties may also be used when modifying an existing keystore. The
1174# properties can be overridden by a KeyStore API that specifies its own
1175# algorithms and parameters.
1176#
1177# If an existing PKCS12 keystore is loaded and then stored, the algorithm and
1178# parameter used to generate the existing Mac will be reused. If the existing
1179# keystore does not have a Mac, no Mac will be created while storing. If there
1180# is at least one certificate in the existing keystore, the algorithm and
1181# parameters used to encrypt the last certificate in the existing keystore will
1182# be reused to encrypt all certificates while storing. If the last certificate
1183# in the existing keystore is not encrypted, all certificates will be stored
1184# unencrypted. If there is no certificate in the existing keystore, any newly
1185# added certificate will be encrypted (or stored unencrypted if algorithm
1186# value is "NONE") using the "keystore.pkcs12.certProtectionAlgorithm" and
1187# "keystore.pkcs12.certPbeIterationCount" values defined here. Existing private
1188# and secret key(s) are not changed. Newly set private and secret key(s) will
1189# be encrypted using the "keystore.pkcs12.keyProtectionAlgorithm" and
1190# "keystore.pkcs12.keyPbeIterationCount" values defined here.
1191#
1192# In order to apply new algorithms and parameters to all entries in an
1193# existing keystore, one can create a new keystore and add entries in the
1194# existing keystore into the new keystore. This can be achieved by calling the
1195# "keytool -importkeystore" command.
1196#
1197# If a system property of the same name is also specified, it supersedes the
1198# security property value defined here.
1199#
1200# If the property is set to an illegal value, an iteration count that is not
1201# a positive integer, or an unknown algorithm name, an exception will be thrown
1202# when the property is used. If the property is not set or empty, a default
1203# value will be used.
1204#
1205# Some PKCS12 tools and libraries may not support algorithms based on PBES2
1206# and AES. To create a PKCS12 keystore which they can load, set the system
1207# property "keystore.pkcs12.legacy" which overrides the values of the properties
1208# defined below with legacy algorithms. Setting this system property (which can
1209# only be enabled and has no value) is equivalent to
1210#
1211#   -Dkeystore.pkcs12.certProtectionAlgorithm=PBEWithSHA1AndRC2_40
1212#   -Dkeystore.pkcs12.keyProtectionAlgorithm=PBEWithSHA1AndDESede

1214#   -Dkeystore.pkcs12.certPbeIterationCount=50000
1215#   -Dkeystore.pkcs12.keyPbeIterationCount=50000
1216#   -Dkeystore.pkcs12.macIterationCount=100000
1217#
1218# Also, you can downgrade an existing PKCS12 keystore created with stronger
1219# algorithms to legacy algorithms with
1220#
1221#    keytool -J-Dkeystore.pkcs12.legacy -importkeystore -srckeystore ks -destkeystore ks

1484# Policy for non-forwardable service ticket in a S4U2proxy request
1485#
1486# The Service for User to Proxy (S4U2proxy) Kerberos extension enables a middle service
1487# to obtain a service ticket to another service on behalf of a user. It requires that
1488# the user's service ticket to the first service has the forwardable flag set [1].
1489# However, some KDC implementations ignore this requirement and accept service tickets
1490# with the flag unset.
1491#
1492# If this security property is set to "true", then
1493#
1494# 1) The user service ticket, when obtained by the middle service after a S4U2self
1495#    impersonation, is not required to have the forwardable flag set; and,
1496#
1497# 2) If a S4U2proxy request receives a KRB_ERROR of the KDC_ERR_BADOPTION error code
1498#    and the ticket to the middle service is not forwardable, OpenJDK will try the same
1499#    request with another KDC instead of treating it as a fatal failure.
1500#
1501# The default value is "false".
1502#
1503# If a system property of the same name is also specified, it supersedes the
1504# security property value defined here.
