Security tools and generators
A password generated by a website that then transmits it is not a secure password, whatever the site says about its logging. These tools use the Web Crypto API in your browser — crypto.getRandomValues() for randomness and SubtleCrypto for hashing — so the output exists only in your tab.
That distinction matters more than it sounds. Cryptographically secure randomness is what makes a generated password unpredictable, and it is not what Math.random() provides, despite how many generators rely on it.

- Live real-time hash generation
Frequently Asked Questions
Are generated passwords ever transmitted?
No. Generation uses the Web Crypto API in your browser, and the result exists only in your tab's memory and clipboard. Nothing is sent, logged, or stored.
Can a hash be reversed?
No. Hashing is one-way by design and discards information. Services advertising 'hash decryption' are looking the digest up in a table of common inputs, which works for weak passwords and not for arbitrary data.
Should I hash passwords with SHA-256?
No. Fast hashes are the wrong tool for password storage precisely because they are fast. Use a deliberately slow, salted algorithm such as bcrypt, scrypt, or Argon2.
