Frequently Asked Questions

What is a hash?
A hash function converts input data of any size into a fixed-size string. The same input always produces the same hash, but it is practically impossible to reverse the hash back to the original data.
Which hash algorithm should I use?
SHA-256 is recommended for most purposes. MD5 and SHA-1 are considered insecure for cryptographic use but are still used for checksums and non-security purposes.
