  • IS.HASH.HMACSHA1: Generating HMAC-SHA1 Values with Generic MultiValue BASIC

    The Message Authentication Code (MAC) is a widely used technique for performing message authentication. HMAC (short for "keyed-Hashing for Message Authentication"), a variation on the MAC algorithm, has emerged as an Internet standard for a variety of applications.

  • IS.HASH.SHA1: Generating with UniBASIC DIGEST command

    In cryptography, SHA-1 (Secure Hash Algorithm 1) is a cryptographic hash function designed by the United States National Security Agency and is a U.S. Federal Information Processing Standard published by the United State NIST. SHA1 is used in many places to generate a unique Hash value representing a string or file. It is widely used in place of MD4 and MD5 a more secure hash value. While not as secure as SHA256, it is still used many places for data integrity, version control, and other features that need an unique one-way signatures.
