+# 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
+
+# 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
