SSL Cipher Specification (SSLCIPH)

This attribute specifies a single CipherSpec for a TLS or SSL connection.

Every WebSphere MQ channel definition includes the SSLCIPH attribute. The value is a string with a maximum length of 32 characters.

Note the following:
  • The SSLCIPH attribute can contain a blank value, meaning that you are not using SSL or TLS. If one end of the channel has a blank SSLCIPH attribute, the other end of the channel must also have a blank SSLCIPH attribute.
  • Alternatively, if SSLCIPH contains a nonblank value, the channel attempts to use the specified cipher to utilize SSL or TLS. Again, in this case, both ends of the channel must specify the same SSLCIPH value.

It is valid only for channels with a transport type (TRPTYPE) of TCP. If the TRPTYPE is not TCP, the data is ignored and no error message is issued.
