GUIDE & CONTEXT

About this tool

A hash maps input bytes to a fixed-size digest; HMAC adds a shared secret to authenticate a message; PBKDF2 repeatedly derives bytes from a password and salt. These operations serve different purposes. MD5 and SHA-1 are included for legacy compatibility and must not be used where collision resistance is required.

How to use it

  1. Choose hash, HMAC or PBKDF2 and the available digest algorithm.
  2. Enter the UTF-8 text and, when needed, a key or salt, iteration count and output length.
  3. Choose hexadecimal or Base64 output, calculate and compare the result byte-for-byte with your expected value.
Example

SHA-256 of abc is ba7816bf8f01cfea414140de5dae2223b00361a396177a9cb410ff61f20015ad.
