python3 实现 google authenticator 认证/校验

生成验证码

# -*- encoding: utf-8 -*-"
# @Module  : google auth
import hmac, base64, struct, hashlib, time


def get_hotp_token(secret, intervals_no):
    key = base64.b32decode(secret, True)
    msg = struct.pack(">Q", intervals_no)
    h = hmac.new(key, msg, hashlib.sha1).digest()
    o = ord(chr(h[19])) & 15
    h = (struct.unpack(">I", h[o:o+4])[0] & 0x7fffffff) % 1000000
    return h

def get_totp_token(secret):
    return get_hotp_token(secret, intervals_no=int(time.time())//30)

value = get_totp_token("UNRNQAU5EIFMSMJY")
print(f"{str(value).zfill(0)}")

校验验证码

# -*- encoding: utf-8 -*-"
# @Module  : google auth
import pyotp

def Google_Verify_Result(secret_key, verifycode):
    t = pyotp.TOTP(secret_key)

    result = t.verify(verifycode)  # 对输入验证码进行校验，正确返回True
    msg = result if result is True else False
    return msg


msg = Google_Verify_Result("UNRNQAU5EIFMSMJY", "888888")
print(msg)
