hmac - Compute HMAC in base64 with different algorythms
hmac(key:string, text:string[, algo: integer])
This function compuite HMAC in BASE64.
From Wikipedia:
In cryptography, an HMAC (sometimes disabbreviated as either keyed-hash message authentication code or hash-based message authentication code) is a specific type of message authentication code (MAC) involving a cryptographic hash function and a secret cryptographic key. It may be used to simultaneously verify both the data integrity and the authentication of a message, as with any MAC. Any cryptographic hash function, such as MD5 or SHA-1, may be used in the calculation of an HMAC; the resulting MAC algorithm is termed HMAC-X, where X is the hash function used (e.g. HMAC-MD5 or HMAC-SHA1). The cryptographic strength of the HMAC depends upon the cryptographic strength of the underlying hash function, the size of its hash output, and the size and quality of the key.
