Turn text into a SHA checksum.
Generate SHA-256, SHA-384 or SHA-512 hashes locally for quick integrity checks, comparisons and technical workflows.
The text you enter stays in your browser and is processed with the Web Crypto API.
SHA-256 checksum
Your checksum will appear here.A hash is a fingerprint for data, not encryption. You cannot turn a SHA hash back into the original text.
The annoying bit
Someone said 'compare the SHA-256.' Cool. Where do you do that?
You don't necessarily need a cryptography lesson. Sometimes you have a value, someone gave you a checksum, and you just need to turn yours into the same kind of fingerprint so you can compare them.
Worth knowing
A hash is a fingerprint, not encryption.
If you are comparing two values, use the same algorithm and compare the full hash rather than just the beginning or end.
For file or release verification, compare against a checksum published by a source you already trust. Raw SHA hashes are not suitable on their own for storing user passwords.
In plain English
Matching fingerprints, basically.
The same input with the same SHA algorithm produces the same hash. Your input is processed locally with the Web Crypto API and is not uploaded by this tool.
Use the result where you need it, then move on.
