SHA-256

SHA-1

MD5

Not cryptographically secure — for checksums only, not passwords or security purposes.

How it works

SHA-256 and SHA-1 use the browser's native Web Crypto API; MD5 runs through a small standalone implementation since browsers no longer support it natively. All hashing happens locally - nothing is uploaded.
