SHA-224 password generator

This easy-to-use tool allows you to generate the SHA-224 generator version of any string. To use it, simply enter the text you want to convert below and click the “Generate” button.

People reach for SHA-224 when they want a compact, strong digest with a familiar NIST-backed pedigree. It’s one of the SHA-2 family hashes: faster than SHA-512 on some platforms and producing a 224-bit (28-byte) output. That makes it an attractive building block if you want to derive passwords deterministically or to produce a short, high-entropy token.

Before we dive into practical examples, a quick reality check: SHA-224 is a cryptographic hash, not a password-hashing function. That distinction matters depending on your goal:

  • If you want to generate a new random password for logging into a website, you should rely primarily on a cryptographically secure random generator (e.g., Python’s secrets), and you can optionally hash that output with SHA-224 to format it.
  • If you want to store user passwords or protect them server-side, don’t use bare SHA-224. Instead use a slow, memory-hard KDF like Argon2, bcrypt, scrypt, or PBKDF2 with many iterations.
  • If you want a deterministic password (site-specific passwords generated from a master passphrase), HMAC or a proper KDF (PBKDF2/HKDF/Argon2) is better — but a carefully used HMAC-SHA-224 can be acceptable for some low-risk uses.
