This can then be encoded in a QR Code and used to provision the Google Authenticator app. For module-internal use. See also: https://github.com/google/google-authenticator/wiki/Key-Uri-Format :param secret: the hotp/totp secret used to generate the URI :param name: name of the account :param initial_count: starting counter value, defaults to None. If none, the OTP type will be assumed as TOTP. :param issuer: the name of the OTP issuer; this will be the organization title of the OTP entry in Authenticator :param algorithm: the algorithm used in the OTP generation. :param digits: the length of the OTP generated code. :param period: the number of seconds the OTP generator is set to expire every code. :param image: optional logo image url :returns: provisioning uri N�sha1� � �hotp�totpzotpauth://{0}/{1}?{2}r �:r �counterr r r �httpsz{} is not a valid urlr �+z%20) r �upperr �scheme�netloc�path� ValueError�formatr �replace)r r r r r r r r �is_initial_count_present�is_algorithm_set� is_digits_set� is_period_set�otp_type�base_uri�url_args�label� image_uri�uri� r, �>/usr/local/CyberCP/lib/python3.10/site-packages/pyotp/utils.py� build_uri s4 # r. �s1�s2c C s. t �d| �} t �d|�}t| �d�|�d��S )a Timing-attack resistant string comparison. Normal comparison using == will short-circuit on the first mismatching character. This avoids that by scanning the whole string, though we still reveal to a timing attack whether the strings are the same length. �NFKCzutf-8)� unicodedata� normalizer �encode)r/ r0 r, r, r- � strings_equalM s r5 )NNNNNN)r2 �hmacr �typingr r r � urllib.parser r r �str�intr. �boolr5 r, r, r, r- �<module> s< ��������� �F
