+# "CertConstraint" specifies additional constraints for
+# certificates that contain algorithms that are restricted:
+#
+# Â Â "jdkCA" prohibits the specified algorithm only if the algorithm is used
+# Â Â Â Â in a certificate chain that terminates at a marked trust anchor in the
+# Â Â Â Â lib/security/cacerts keystore. Â All other chains are not affected.
+# Â Â Â Â If the jdkCA constraint is not set, then all chains using the
+# Â Â Â Â specified algorithm are restricted. jdkCA may only be used once in
+# a DisabledAlgorithm expression.
+# Â Â Â Â Example: Â To apply this constraint to SHA-1 certificates, include
+# Â Â Â Â the following: Â "SHA1 jdkCA"
