Verify ModeCompare file against expected checksum
Auto-detectIdentifies algorithm by hash length automatically
SecureFiles processed server-side, never stored
Recommended Algorithms
SHA-256 Popular
Most widely used — perfect for general use
SHA-512
Higher security, ideal for sensitive files
BLAKE2b Fast
Fastest modern algorithm with high security
SHA3-256/512 Modern
Latest standard, maximum future-proofing
MD5 / SHA-1 Legacy
Integrity only — not for security use
