FAQ

What is a hash function?

A hash function maps input data of arbitrary size to a fixed-size output (hash value). It's one-way - you cannot reverse a hash to get the original input.

What's the difference between SHA-256 and SHA-512?

SHA-256 produces a 256-bit (32-byte) hash, while SHA-512 produces a 512-bit (64-byte) hash. SHA-512 is more secure but slightly slower.
