Generated HMAC-SHA-256 Hash

Description

  • This tool generates the HMAC-SHA-256 hash of a given message and secret key.

Facts

  • HMAC-SHA-256 is a keyed hash-based message authentication code (HMAC) that uses the SHA-256 algorithm from the Secure Hash Algorithm 2 family of algorithms.
  • HMAC-SHA-256 is a cryptographic hash function which takes an input text and secret key and generates a 256-bit hash value which is 64 characters in length.
  • HMAC-SHA-256 provides authentication via a shared secret key that is known to both the sender and receiver of a message.
  • HMAC-SHA-256 is often used in creating digital signatures to allow a receiver to verify the integrity of a message.
  • The HMAC-SHA-256 hash value of an empty string or empty file is b613679a0814d9ec772f95d778c35fc5ff1697c493715653c6c712144292c5ad.
