Cipher suite definitions

The following tables outline:
  • Cipher suite definitions for SSL V2
  • 2-character and 4-character cipher suite definitions for SSL V3, TLS V1.0, TLS V1.1, and TLS V1.2.
  • Cipher suite definitions for SSL V3, TLS V1.0, TLS V1.1, and TLS V1.2 by supported protocol, symmetric algorithm, and message authentication algorithm
  • Cipher suite definitions for SSL V3, TLS V1.0, TLS V1.1, and TLS V1.2 by key-exchange method and signing certificate
  • Supported elliptic curve definitions for TLS V1.0, TLS V1.1, and TLS V1.2.
Note: When executing in non-FIPS mode, if either the System SSL Security Level 3 FMID is installed or the CPACF Feature 3863 is installed, the ciphers listed under the Security Level 3 FMID column are allowed to be used.

1 SSL V3, TLS V1.0, and TLS V1.1 imposed restrictions on the signing algorithm that must be used to sign a server certificate when using any cipher suites that use a Diffie-Hellman based key-exchange. The TLS V1.2 protocol does not impose such restriction. If the server certificate signing algorithm is listed in the signature algorithm pairs that are specified by the client, the certificate can be used.
