Frequently Asked Questions

A hash function is a mathematical algorithm that converts input data into a fixed-size string of characters. It's deterministic (same input = same output) and one-way (you can't reverse the hash to get the original data).

For security purposes, use SHA-256 or SHA-512. MD5 and SHA-1 are considered weak for cryptographic purposes but are still useful for checksums and non-security applications. SHA-256 offers a good balance of security and performance.
