Overview

Package hmac implements the Keyed-Hash Message Authentication Code (HMAC) as defined in U.S. Federal Information Processing Standards Publication 198.

An HMAC is a cryptographic hash that uses a key to sign a message. The receiver verifies the hash by recomputing it using the same key.

Functions

func Sign

func Sign(hashName string, key []byte, data []byte) ([]byte, error)

Sign returns the HMAC signature of the data, using the provided key and hash function.

Supported hash functions: "MD5", "SHA1", "SHA224", "SHA256", "SHA384", "SHA512", "SHA512_224", and "SHA512_256".
