CipherSpecs and CipherSuites in IBM MQ

From IBM MQ Version 9.0.0, Fix Pack 3 and IBM MQ Version 9.0.5, IBM MQ supports TLS V1.2 CipherSpecs, and RSA and Diffie-Hellman algorithms. However, we can enable deprecated CipherSpecs, if you need to do so.

See Enabling CipherSpecs for information on:

IBM MQ supports the RSA and Diffie-Hellman key exchange and authentication algorithms. The size of the key used during the TLS handshake can depend on the digital certificate we use, but some CipherSpecs include a specification of the handshake key size. Larger handshake key sizes provide stronger authentication. With smaller key sizes, the handshake is faster.
