Frequently Asked Questions
Is my password input secure?
Yes, 100%. The generator utilizes your browser's Web Crypto API locally. Absolutely no input text or output passwords are ever sent to a server.
What makes this password generator secure?
Unlike standard generators using Math.random(), we leverage window.crypto.getRandomValues, which supplies cryptographically secure pseudo-random numbers (CSPRNG) suitable for high-security passwords.
How does a cryptographic hash work?
A hash function takes an input string and converts it into a fixed-size sequence of hexadecimal characters (e.g. 64 characters for SHA-256). This process is unidirectional and irreversible.
What is SHA-256 used for?
SHA-256 is commonly used for data integrity checks, password hashing verifications, blockchain address generation, and cryptographic signatures.
