Hash Generator: SHA MD5 HMAC

Hash Generator creates and compares cryptographic hashes and checksums for text and files, directly on your phone. Whether you are a developer verifying a build, a security professional checking a signature, or someone confirming that a download arrived intact, it does the job in a couple of taps. 12 HASHING ALGORITHMS SHA-1, SHA-224, SHA-256, SHA-384, SHA-512, SHA-512/224, SHA-512/256, MD5, CRC32, plus keyed HMAC-SHA256, HMAC-SHA512 and HMAC-MD5. HASH ANY FILE, INCLUDING VERY LARGE ONES Pick a file and get its checksum. Files are read as a stream, so multi-gigabyte videos, ISO images and APKs hash without running out of memory. A progress bar shows the percentage as it works. HASH TEXT Type or paste any text and generate its hash instantly. Useful for quick checks, test vectors and debugging. KEYED HMAC Enter your own secret key to generate HMAC-SHA256, HMAC-SHA512 or HMAC-MD5. Handy for verifying API request signatures, webhook payloads and message authentication codes. COMPARE HASHES Paste an expected checksum and compare it against the one you generated. The comparison is case-insensitive, so a value copied from a download page, from certutil on Windows or from sha256sum on Linux will match whether it is upper or lower case. HISTORY Every hash you generate is saved with its algorithm, input and timestamp. Tap an entry to copy it, swipe to delete a single item, or clear the whole list at once. COPY AND SHARE Copy any hash to the clipboard with one tap, or share it straight into another app. SEPARATE RESULTS FOR TEXT AND FILES The Text and File tabs keep their own results, so generating one never overwrites the other. SIX LANGUAGES English, French, German, Arabic, Urdu and Hindi. VERIFY YOUR DOWNLOADS Publishers often list an SHA-256 or MD5 checksum next to a download link. Hash the file you actually received, paste in the published value, and confirm the two match before you install or trust it. A single changed byte produces a completely different hash, which makes this a reliable integrity check. A NOTE ON ALGORITHM CHOICE SHA-256 is the sensible default for integrity checks. MD5 and SHA-1 remain useful for matching legacy checksums, but both are considered broken against deliberate tampering and should not be relied on for security. CRC32 detects accidental corruption, not malicious modification. PRIVACY All hashing is performed on your device. The files you select and the text you enter are never uploaded to a server and are not sent anywhere for processing. Found a bug or have a feature request? Email on support and we will take a look.
