The SHA hash generator converts text into a deterministic SHA-256, SHA-384 or SHA-512 digest using the browser’s Web Crypto API. The same input and algorithm always produce the same digest, which is useful for integrity checks and technical demonstrations.

A hash is one-way and is not encryption, so it cannot be decoded back into the original text. Do not use a single unsalted SHA hash to store passwords; production authentication systems need a dedicated password-hashing function such as Argon2, scrypt or bcrypt.
