GREYMIND · ACSS · FILE INTEGRITY
SHA-256 file integrity.
Generate a SHA-256 digest for a file, or verify a file against an expected digest. Both run entirely in this browser.
Runs locally
Your selected file is processed in this browser and is not uploaded to GreyMind.
Generate SHA-256
Select a file to compute its SHA-256 digest locally. Copy the full 64-character digest or download a .sha256 sidecar.
Verify a SHA-256 digest
Compare a selected file against an expected SHA-256. Uppercase, whitespace and SHA256SUMS-style lines are accepted and normalised before comparison.
