Hash "Hello, world!"
text = Hello, world!
Result: Enter text and click Hash to see the SHA-224 digest.
SHA-224 Hash Generator
Convert text to its SHA-224 hash (digest) using the Web Crypto API. The output is a hexadecimal string representing the hash value. SHA-224 is a widely-used cryptographic hash function for integrity verification and digital signatures. Everything runs in your browser.

Frequently asked questions
What is SHA-224?
SHA-224 is a cryptographic hash function that produces a fixed-size digest from arbitrary input. It is widely used for integrity verification and digital signatures.
Is hashing the same as encryption?
No. Hashing is a one-way operation - you cannot recover the original input from the hash. Encryption is reversible with the correct key. Hashing is used for integrity checks and password storage, while encryption is used for confidentiality.
Can two different inputs produce the same hash?
Technically yes (a "collision"), but for modern algorithms like SHA-256, finding collisions is computationally infeasible.
Is my text sent to a server?
No. Hashing happens entirely in your browser using the Web Crypto API. Nothing you type is transmitted anywhere.
