Hash Generator computes a fixed-length fingerprint of any text using common algorithms like MD5, SHA-1, and SHA-256. The same input always yields the same hash, while the smallest change yields a completely different one, which is what makes hashes ideal for verifying integrity.
Hashing is one-way: you cannot reverse a hash to recover the original input. 'Reverse hash' lookups merely match against precomputed tables of common values; they don't invert the maths. That irreversibility is a feature, letting you confirm two pieces of data are identical without storing the data itself.
Algorithm choice matters. SHA-256 is a good modern default for integrity. MD5 and SHA-1 remain useful for fast, non-security checksums and deduplication, but they're cryptographically broken and must never be used for passwords or security verification. And passwords specifically should use a salted password-hashing function like bcrypt or argon2, not a plain hash.
All hashing runs in your browser, so your input never leaves your device. Pair Hash Generator with the other ToolsMonk developer tools for encoding, tokens, and formatting in one place.

Use SHA-256 by default; reserve MD5/SHA-1 for non-security checksums where speed matters
Never hash passwords with a plain hash function, use bcrypt or argon2 with a salt instead
A hash is a fingerprint, not encryption, you can verify a value against it, but never recover the original from it
Common questions about this tool, its workflow, and what to expect before you use it.
NIST
Specifies SHA-1 and the SHA-2 family (SHA-256, SHA-384, SHA-512).
IETF
Specifies MD5, which is fine as a checksum and unsafe for passwords or signatures.
