HMAC Functions

This tool generates a cryptographic Hashed Message Authentication Code (HMAC) from an input string and a key. Enter the text string that you want hashed, a key and selected the hash function you want to use.

Note that these are server-side calculations, so the data you enter has to be submitted to the server to calculate the HMAC.
