Input and result notes

TOTP must match the verifier's Base32 secret, algorithm, digits and time step. Clock drift can cause rejection; protect the shared secret as a login credential.

Security
  • Password Generator

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

  • 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.
