HMAC Generate (CSNBHMG)

Use the HMAC Generate verb to generate a keyed hash Message Authentication Code (HMAC) for the message string provided as input.

An HMAC key that can be used for generate is required to calculate the HMAC.

The HMAC key supplied in a variable-length symmetric key token may contain a secure or a clear key value. Clear HMAC keys can be built using the Key Token Build2 (CSNBKTB2) callable service.
