Need a hash calculator that just works? HashCalc computes MD5, SHA-1, SHA-256, SHA-384, SHA-512 and CRC32 the instant you type or paste — no upload, no wait, no guessing. Most "hash" tools send your text to a website or bury the digest you need under ads. HashCalc runs every algorithm locally on your device and shows the results side by side, so you can copy the exact digest you want and move on. WHAT YOU GET - Live digests for MD5, SHA-1, SHA-256, SHA-384, SHA-512 and CRC32 as you type - Verify a download in one step: paste the expected checksum and see match or mismatch instantly - Compare two hashes side by side to confirm two files or strings are identical - Sign messages with HMAC using your secret key across the full SHA family - Checksum any file — HashCalc streams it through the hasher so even large files hash cleanly - A saved history of recent hashes plus a plain-language reference on MD5, SHA, CRC32 and HMAC PERFECT FOR - Developers signing API requests and webhooks with HMAC - Anyone verifying a downloaded ISO, installer or backup against its posted checksum - Security-minded users checking file integrity without touching the cloud - Students and learners who want to see how hashing actually works WHY NOT JUST USE A WEBSITE? Web hashers make you paste sensitive text into a server you don't control, and they break the moment you lose signal. HashCalc computes everything on-device, works fully offline, and never sends your input anywhere. PRIVACY Every digest is computed on your device. No accounts, no servers, no tracking — your text and files never leave your phone. FULL ACCESS The free app covers core hashing. A HashCalc membership unlocks everything: all six algorithms, verify and compare, HMAC signing, file hashing and saved history. Choose a weekly or yearly plan, or a one-time lifetime purchase — subscriptions renew until cancelled and can be cancelled anytime. Type your first string and watch the digests appear.
