FAQ

Why use hashes?

Same input always produces the same hash, which is used to verify file integrity and compare checksums — useful when checking whether a downloaded file matches the original.

Is MD5 safe?

MD5 is no longer recommended for cryptographic use (collisions exist), but is still widely used for non-cryptographic checksums and identifiers — included for compatibility.

Can I hash large files?

Yes, though the file is loaded fully into memory. We recommend ≤100MB on mobile devices.

Are files uploaded to a server?

No. All hashing happens in your browser via the Web Crypto API and a small client-side MD5 library.

Should I use SHA-256 or SHA-512?

SHA-256 is sufficient for most cases. SHA-512 produces a longer (128-char) hash and is used when stronger security or longer output is needed.
