Frequently Asked Questions
What is a hash function?+
A hash function converts any input into a fixed-length string. The same input always produces the same hash, but the original data cannot be recovered from the hash.
Is MD5 still safe to use?+
No. MD5 is cryptographically broken. Use SHA-256 or SHA-512 for any security-sensitive hashing.
