Frequently asked questions
Are my files uploaded?
No. Hashes are calculated in your browser.
Should I use MD5 for passwords?
No. MD5 and SHA-1 are fine for checksums but are not safe for passwords or signatures.
Which hash should I use?
Use SHA-256 or stronger for integrity checks; MD5 and SHA-1 are outdated for security.
Can a hash be reversed?
No. Hashes are one-way, though weak inputs can be guessed with brute force.
