Hash algorithm comparison

Why are SHA-256 and SHA-512 hashes different lengths?

SHA-256 outputs 256 digest bits while SHA-512 outputs 512. In hexadecimal that is 64 characters versus 128 characters for the same exact text. This tool is free to use. No account or payment is required.

  • Browser-local hashing

Steps

  1. Confirm both sides use the same source text.
  2. Check whether the algorithm is SHA-256 or SHA-512.
  3. Compare digest values only after algorithm and input both match.

SHA-256 and SHA-512 are distinct algorithms

Both belong to SHA-2, but they have different digest sizes and output values. SHA-512 is not a padded or extended rendering of SHA-256.

Common questions

Frequently asked questions

Is SHA-512 just two SHA-256 hashes joined together?

No. SHA-512 is its own SHA-2 algorithm with a 512-bit digest.

How long are the hexadecimal outputs?

SHA-256 is 64 hex characters and SHA-512 is 128.
