Frequently Asked Questions

Clear answers to common cryptographic and implementation questions.

What is the difference between a checksum and a cryptographic hash?

Checksums (like CRC32) are designed to detect accidental errors (e.g. transmission noise) quickly. Cryptographic hashes (like SHA-256) are designed to resist deliberate tampering and collisions.
