Frequently Asked Questions

What is the difference between SHA-1 and SHA-256?

SHA-256 is more secure than SHA-1. SHA-1 produces 160-bit hashes, while SHA-256 produces 256-bit hashes. SHA-1 is no longer considered cryptographically secure.

Are my inputs sent to a server?

No, all hashing is done locally in your browser using the Web Crypto API. Your data never leaves your device.

Which hash algorithm should I use?

For security purposes, use SHA-256 or SHA-512. SHA-1 is considered weak and should only be used for legacy compatibility.
