Frequently Asked Questions

What is a cryptographic checksum and how does it detect changes?

A cryptographic hash is a one-way mathematical function that outputs a unique, fixed-length digest. Due to the avalanche effect, changing even a single byte in your input produces a completely different hash.

Are my private texts or keys uploaded during hash computation?

No. All mathematical routines are executed locally via client-side JavaScript, guaranteeing that your proprietary codes and parameters remain entirely on your device.

What are the distinct benefits of SHA-3 compared to older SHA family hash systems?

SHA-3 is based on the innovative Keccak 'sponge construction' family. It was chosen by NIST to provide a structurally different hashing model from SHA-2, ensuring protection against potential collision exploits.
