About Hash Generator
The Hash Generator computes cryptographic digests of your text — MD5, SHA-1, SHA-256, SHA-384 and SHA-512.
SHA hashes are produced with the browser's native Web Crypto implementation; MD5 is computed in JavaScript since browsers don't expose it.
Hashes are deterministic fingerprints: the same input always yields the same output, but you cannot reverse the output back to the input.
Use them to verify file or text integrity, compare values without storing the original, generate cache keys, or check a checksum someone published. (MD5 and SHA-1 are fine for non-security checksums but should not be used for new security-critical work.) All hashing runs locally — your input is never uploaded.
FAQ
Can a hash be reversed?
No. Hashes are one-way. Identical input gives identical output, but the original cannot be recovered from the hash.
Should I use MD5 for passwords?
No. MD5 and SHA-1 are unsuitable for password storage or signatures. Use them only for non-security checksums.
