+# "CertConstraint" specifies additional constraints for
+# certificates that contain algorithms that are restricted:
+#
+# �� �� "jdkCA" 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. �� All other chains are not affected.
+# �� �� �� �� 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"
