Frequently asked questions
Is my file uploaded?
No. The hash is computed entirely in your browser using the Web Crypto API. Your file never leaves your device.
Which hash algorithm should I use?
SHA-256 is the most widely used for integrity verification. MD5 and SHA-1 are included for compatibility but are not recommended for security purposes.
