Frequently Asked Questions

What is a hash?▾

A hash is a fixed-size fingerprint of a message. The same input always produces the same digest, and changing even one byte produces a completely different digest.

Is MD5 or SHA-1 still secure?▾

No. MD5 and SHA-1 have known collision attacks and should not be used for security-critical purposes. Prefer SHA-256 or a modern password-hashing function.
