What is the difference between HMAC and regular hashing?

HMAC uses a secret key to hash a message, verifying both integrity and authenticity. Regular hashing only verifies integrity and cannot prevent tampering.

Which hash algorithms are supported?

It supports HMAC-MD5, HMAC-SHA1, HMAC-SHA256, HMAC-SHA512 and other common algorithms, with Hex or Base64 output encoding.
