Generated HMAC-SHA-512 Hash

Description

  • This tool generates the HMAC-SHA-512 hash of a given message and secret key.

Facts

  • HMAC-SHA-512 is a keyed hash-based message authentication code (HMAC) that uses the SHA-512 algorithm from the Secure Hash Algorithm 2 family of algorithms.
  • HMAC-SHA-512 is a cryptographic hash function which takes an input text and secret key and generates a 512-bit hash value which is 128 characters in length.
  • HMAC-SHA-512 provides authentication via a shared secret key that is known to both the sender and receiver of a message.
  • HMAC-SHA-512 is often used in creating digital signatures to allow a receiver to verify the integrity of a message.
  • The HMAC-SHA-512 hash value of an empty string or empty file is b936cee86c9f87aa5d3c6f2e84cb5a4239a5fe50480a6ec66b70ab5b1f4ac6730c6c515421b327ec1d69402e53dfb49ad7381eb067b338fd7b0cb22247225d47.
