About SHA hashes
A hash function turns any input into a fixed-length "fingerprint". The SHA-2 family (SHA-256, SHA-384, SHA-512) is widely used to verify file integrity, store password checks, sign data and generate IDs — the same input always produces the same hash, and even a tiny change produces a completely different one. SHA-1 is included for legacy compatibility but is no longer considered secure against collisions.
These hashes are computed with your browser's native crypto.subtle Web Crypto API over the UTF-8 bytes of your text, entirely on your device. Note that hashing is one-way — you can't turn a hash back into the original text.
