Python implementation of the three main OATH specifications: HOTP, TOTP and OCRA

Python OATH

python-oath is a package implementing the three main OATH specifications:

• HOTP, an event based one-time password standard – OTP – using HMAC signatures,

• TOTP, a time based OTP,

The main APIs are:

• hotp, to generate a password.

• accept_hotp, to check a received password,

• totp and accept_totp, the same for the TOTP standard.

• GoogleAuthenticator to parse Google Authenticator URI

• from_b32key to create a a GoogleAuthenticator object from a simple base32 key
