SHA-224 Hash Generator
Compute a SHA-224 digest — the SHA-256 compression function with a different initial value, truncated to 224 bits.
Input
SHA-224
Enter something above to see the result.
How to read a hash
A hash is a fixed-length fingerprint of its input. The same input always gives the same output, and changing a single bit changes roughly half the output bits — which is what makes a hash useful for spotting corruption.
Hashing is one-way: you cannot recover the input from the digest. That is not the same as secrecy, though. If the set of possible inputs is small, an attacker simply hashes all of them and looks yours up.
Text and files
The text tab hashes exactly the characters you type, encoded as UTF-8. The file tab reads the file locally and hashes its raw bytes. Neither sends anything to a server, so the digest of a private key or a customer export is safe to compute here.
Frequently asked questions
Why does adding a newline change the whole hash?
By design. A hash is meant to be sensitive to every bit of its input, so an invisible trailing newline produces a completely unrelated digest.
Does the text encoding matter?
Yes. This tool encodes text as UTF-8. Hashing the same characters as UTF-16 or EUC-KR produces a different digest, which is a common cause of mismatches between tools.
