About this tool
A cryptographic hash function turns any input — a word, a file, a document — into a fixed-length string of hex digits called a digest. The same input always produces the same digest, but changing even one character produces a completely different one.
SHA-256 and SHA-512 are widely used for data integrity checks, password storage (with a salt) and digital signatures. SHA-1 is now considered weak for security purposes but is still used in version-control systems like Git.
How to use it
- Type or paste the text you want to hash.
- All four digests — SHA-1, SHA-256, SHA-384, SHA-512 — are computed instantly.
- Copy the digest you need.
Examples
Common problems
- Two runs on the same text give different results.
- Check for trailing spaces or newlines in the input. Even a single invisible character changes the hash completely.
