Hash Generator

Calculate SHA-1, SHA-256, SHA-384, SHA-512 text hashes.

Text
Hash

Hash functions transform data of arbitrary length into a fixed string of characters, used for integrity checks or password storage. Calculation is done via the Web Crypto API directly in the browser.

Why is there no MD5?

MD5 is considered cryptographically insecure and is not supported by the browser's standard Web Crypto API; for new projects, SHA-256 and higher is recommended.

Can text be recovered from a hash?

No, hashing is a one-way process; it is impossible to recover original data from a hash.

Which algorithm should I choose?

SHA-256 is the standard choice for most tasks; SHA-512 provides a longer hash for increased resistance.
