SHA-256 hashing in Web Crypto
This page uses the browser Web Crypto API for SHA-256 output, which is useful for checksums and deterministic text fingerprints.
Can SHA-256 be reversed?
No. SHA-256 is a one-way hash. It is not an encryption or password storage system by itself.
Why not MD5?
Modern browser crypto APIs focus on stronger algorithms. This page uses SHA-256 for safer default checksums.
