Is the hash generator (md5, sha-1, sha-256, sha-512) free?

Yes — 100% free, no signup, no usage limits.

Does it save my data?

No. Inputs are processed in your browser and never uploaded to a server.

Yes. The interface is fully responsive and works on iOS and Android.

No — both have known collision attacks. Use SHA-256 or SHA-512 for anything security-sensitive.

Hashes are one-way functions. The only way to 'reverse' one is to brute-force inputs until one produces the same hash.

Compute MD5, SHA-1, SHA-256, and SHA-512 hashes from text. All four update live as you type.

Cryptographic hash functions take any input and produce a fixed-length fingerprint.
