Hash generator
Hash text in the browser. SHA algorithms use Web Crypto; MD5 is computed locally (not for passwords).
About Hash generator
Generate MD5, SHA-1, SHA-256, SHA-384, and SHA-512 hashes from any text with this free online hash generator. Paste a string and get the hex digest instantly, which helps when verifying file-like checksums, comparing integrity values, creating cache keys, and testing hashing logic in your code. SHA algorithms use the Web Crypto API; MD5 is computed locally and is not suitable for storing passwords.
Developers hash cache keys and idempotency strings. Ops people compare a published MD5 or SHA-256 checksum against a value they computed. Students learn how a tiny input change produces a different digest. SHA-256 is a solid default for integrity checks. Prefer SHA-256 or SHA-512 over MD5 and SHA-1 when collision resistance matters. Never use this page as a password hasher for production accounts.
Results update when you run the hash so iteration is fast. Copy the hex digest into a test, a database column, or a ticket. This tool hashes text you paste, not files from disk; for file checksums in other apps, compare against the same algorithm. Pair it with the UUID or password generators when you need random input rather than a digest of known text.
Hashes are computed locally in your browser, so the input text never leaves your device. Secrets you hash for debugging stay private. Use this free MD5 and SHA hash generator whenever you need a hex digest without a terminal.
