Frequently asked questions
Which algorithm should I use?
Use SHA-256 for integrity checks and anything security-related. MD5 and SHA-1 are fine for detecting accidental corruption but are no longer secure.
Can I hash large files?
Yes, as long as the file fits in your browser’s memory — typically up to 1–2 GB.
Is text encoded as UTF-8?
Yes. Text is hashed as UTF-8 bytes, matching most command-line tools.
