About the Hash Generator
The Hash Generator computes MD5, SHA-1, SHA-256 and SHA-512 digests of any text input, producing the fixed-length fingerprint used for checksums, integrity checks and data comparison. Paste your text and instantly get each algorithm's hexadecimal output side by side. The hashing is performed locally in your browser, so the text you enter is never transmitted.
How to use
- Paste or type the text you want to hash.
- Read the generated MD5, SHA-1, SHA-256 and SHA-512 digests.
- Copy the hash you need for your checksum or comparison.
- Re-hash known-good text to verify a file or value matches.
Frequently asked questions
- Which hash algorithm should I use?
- For security-sensitive uses prefer SHA-256 or SHA-512. MD5 and SHA-1 are considered broken for security purposes and should only be used for non-security checksums.
- Can I reverse a hash to get the original text?
- No. Cryptographic hashes are one-way functions. The only way to find an input is to guess and re-hash, which is why hashing is not a substitute for encryption.
- Is my input sent to a server?
- No. All hashes are computed in your browser, so the text you enter stays on your machine.
