HMAC-SHA-1 Hash Generator

This tool generates the HMAC-SHA-1 hash of a given message and secret key. HMAC-SHA-1 is a cryptographic hash function which takes an input text and secret key and generates a 160-bit hash value which is 40 characters in length.

Generated HMAC-SHA-1 Hash

Description

  • This tool generates the HMAC-SHA-1 hash of a given message and secret key.

Facts

  • HMAC-SHA-1 is a keyed hash-based message authentication code (HMAC) that uses the Secure Hash Algorithm 1 (SHA-1).
  • HMAC-SHA-1 is a cryptographic hash function which takes an input text and secret key and generates a 160-bit hash value which is 40 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-1 is often used in creating digital signatures to allow a receiver to verify the integrity of a message.
  • The HMAC-SHA-1 hash value of an empty string or empty file is fbdb1d1b18aa6c08324b7d64b71fb76370690e1d.
