https://en.wikipedia.org/wiki/HMAC

HMAC (hash-based message authentication code) is a message authentication code that involves a cryptographic has function and a secret cryptographic key. It may used to simultaneously verify both the data integrity and the authentication of a message. Any cryptographic has function, such as MD5 or SHA-1, may be used in calculation of the HMAC.

A HMAC can be generated on command-line with OpenSSL.
