Functions
|  | hotp(key, counter, nrDigits=6, hmacHash='SHA1') HOTP - An HMAC-Based One-Time Password Algorithm. key: The HOTP key. Either raw bytes or a base32 encoded string. counter: The HOTP counter integer. nrDigits: The number of digits to return. Can be 1 to 8. hmacHash: The name string of the hashing algorithm. Returns the calculated HOTP token string. totp(key, nrDigits=6, hmacHash='SHA1', t=None) TOTP - Time-Based One-Time Password Algorithm. nrDigits: The number of digits to return. Can be 1 to 8. hmacHash: The name string of the hashing algorithm. t: Optional; the time in seconds. Uses time.time(), if not given. Returns the calculated TOTP token string.
