How it works
- Drop files, or switch to Text.
- Choose the algorithms.
- Copy the hashes, or paste a checksum to verify.
Why use it
- SHA-256 and more.
- Streams big files.
- Verify against a checksum.
- Private.
Questions and answers
What is SHA-256 used for?
Verifying file integrity, signatures and blockchains.
Can SHA-256 be reversed?
No, it is a one way function.

How long does it take to crack a password?
Password strength is about how many passwords could have been chosen, not how complicated one looks. We worked out how long common kinds of passwords hold out against a modern graphics card, and why the ones people invent fall first.
MD5 vs SHA-256: which hash should you use?
MD5 and SHA-256 both turn a file into a short fingerprint, but only one of them can still be trusted when someone might be trying to fool you. We timed seven hash functions and looked at what "broken" really means.
