Can a hash be reversed to get the original text?

No. Hash functions are one-way. The only practical way to confirm a hash is to hash a known value and compare, which is what the Hash Verifier tool does.

Which algorithm should I use?

Use SHA-256 or SHA-512 for integrity and security purposes. MD5 and SHA-1 are fine for non-security checksums but are considered broken for protection against tampering.

Why are hashes different lengths?

Each algorithm has a fixed output size: MD5 is 32 hex characters, SHA-1 is 40, SHA-256 is 64, SHA-384 is 96 and SHA-512 is 128.

Is Hash Generator free to use?

Yes — Hash Generator is completely free, with no registration, no usage limits and no watermarks.

Does this tool upload my files to a server?

No. All processing happens entirely in your browser — nothing is uploaded, stored or shared.

Hash Generator

Generate MD5, SHA-1, SHA-256, SHA-384 and SHA-512 hashes of any text.

A hash function turns any input into a fixed-length fingerprint.

About Hash Generator

Type or paste text and instantly see its MD5, SHA-1, SHA-256, SHA-384 and SHA-512 hashes side by side, ready to copy. Hashes are one-way fingerprints used to verify file integrity, compare passwords stored by other systems, and check that data hasn't changed. Everything is computed in your browser, so your text is never uploaded.

A hash function turns any input into a fixed-length fingerprint. Change one character and the hash changes completely, which makes hashes ideal for checking file integrity, detecting duplicates and comparing values without storing the originals. This hash generator computes MD5, SHA-1, SHA-256, SHA-384 and SHA-512 side by side, all in your browser.
