Hash generator
SHA-1, SHA-256, SHA-512
SHA-1
SHA-256
SHA-384
SHA-512
This hash generator computes the cryptographic digest of a text in SHA-1, SHA-256 or SHA-512. Handy for checking the integrity of a string, comparing two contents or producing a reference fingerprint to keep.
The calculation relies on the browser's Web Crypto API and stays 100% local: your text is never uploaded, no tracking and no ads.
FAQ
Why is MD5 not offered?
The browser's Web Crypto API does not support MD5, so only the SHA algorithms are available.
Can a hash be reversed to recover the text?
No, a hash function is one-way and does not let you recover the input.
Which algorithm should I choose?
SHA-256 is a good default, SHA-512 gives a longer digest, SHA-1 is old and discouraged.
Is my text sent anywhere?
No, hashing happens entirely in your browser.
