Frequently Asked Questions

What is a hash function?

A hash function converts input data of any size into a fixed-size string of characters, which appears random. The same input always produces the same hash.

Which algorithm should I use?

SHA-256 is recommended for most use cases. MD5 and SHA-1 are considered weak for security but are still used for checksums.

Can a hash be reversed?

Cryptographic hash functions are designed to be one-way. You cannot reverse a hash to get the original input.
