About the Hash Generator
Generates cryptographic hashes of any text — MD5, SHA-1, SHA-256 and SHA-512 — computed entirely in your browser. Hashes are one-way fingerprints used for checksums, integrity checks and IDs.
What this tool checks
- Computes MD5, SHA-1, SHA-256 and SHA-512
- One-click copy for each hash
- Nothing is uploaded — all local
Frequently asked questions
Which hash should I use?
SHA-256 for anything security-related; MD5 and SHA-1 are fine for non-security checksums but are considered broken for cryptography.
Can I reverse a hash?
No — hashing is one-way. Identical input always gives the same hash, but you can't derive the input from the hash.
