Text uses UTF-8; files are read in local chunks and never leave the browser.

Usage and safety notes

Local streaming

Files are read in chunks for integrity checks and are never uploaded.

Choose SHA-256 or SHA-512

Prefer SHA-256 or SHA-512 for integrity checks in new systems.

Hashes are not password storage

Do not use MD5, SHA-1, SHA-256, or SHA-512 directly to store passwords.
