Password Generator

Generate passwords with browser cryptographic randomness. Choose length and character sets, then copy the generated passwords.

Input and result notes

Length and the character pool both affect the password space. Avoid password reuse, store generated passwords securely, and consider exposure through shared clipboards.

Security
  • Token Entropy

    Estimate a token's character pool, theoretical entropy, and repetition.

  • PBKDF2 Key Derivation

    Derive key bytes from a password, salt, iteration count, and selected hash algorithm using PBKDF2.

  • HKDF Key Derivation

    Expand input key material using a salt and context information with the HKDF key derivation function.

  • AES-GCM Text Encryption

    Encrypt or decrypt text with a passphrase using AES-GCM, a random salt, and locally derived key material.
