Hash Text/File

Paste text or choose a file to compute MD5, SHA-1, SHA-256, and SHA-512. Runs entirely in your browser — nothing is ever uploaded.

Where this actually gets used: verifying a download (compare the hash here against the SHA256SUMS/.sha256 the publisher lists, to confirm an ISO, installer, or archive wasn't corrupted or tampered with in transit); deduplication (two files with the same hash are byte-for-byte identical, so hashing is a fast way to spot duplicates without a full comparison — this is how the image gallery tool on this site detects re-uploaded images, for example); detecting whether something changed (hash a config file or build output before and after a step, and a differing hash means something moved); and Git internals (every commit and blob in a Git repo is identified by a SHA hash of its contents). One important thing this tool is not for: hashing passwords. A plain hash like these is fast by design, which is exactly wrong for passwords — a leaked password database hashed with plain SHA-256 can be brute-forced at billions of guesses per second; real password storage needs a slow, salted algorithm like bcrypt, scrypt, or Argon2 instead.
