Hash Calculator: MD5 SHA

Compute MD5, SHA-1, SHA-256 and SHA-512 hashes of any text.

Compute MD5, SHA-1, SHA-256, SHA-512 and CRC32 the instant you type. This app is the fast, private hash and checksum toolkit built for developers, security engineers and power users.

WHY THIS APP • Every algorithm at once — MD5, SHA-1, SHA-256, SHA-384, SHA-512 and CRC32 side by side • Verify downloads and backups — paste an expected checksum and see match or mismatch instantly • HMAC message authentication — add a secret key to sign with HMAC-SHA256 and the full SHA family • Hash any file — stream large files through the hasher and confirm integrity in seconds • Copy, compare and reuse — one tap to copy a digest, plus a saved history of past results • 100% on-device — no accounts, no servers, no tracking; your data never leaves your iPhone

HOW IT WORKS

1. Type or paste your text, or pick a file
2. Read every hash live, side by side
3. Copy a digest or paste a checksum to verify

Full access to the app unlocks with a weekly or yearly plan, or a one-time lifetime purchase.
