結(jié)果如下：
In [2]: sign = private_key_signature('123456', 'private.pem')
In [3]: sign
Out[3]: 'Uwa55Oa+ru/QbWBnax7jtjKKNbPHk2Nhe1m8BeS2JmDmd0zHQ0oKq6QJ4A23bG51R/kDhz9J/ipsIPpI7lCWzyM7O91SuSAlnq19XpywOB+uk/4RT/Q8AAndbhPlvP0gYxIkd6BKeWckfjvoBvN0fnM17fHpLo0LJwbYrr6zB6g='
In [6]: result = public_key_verify('123456', sign, 'public.pem')
In [7]: result
Out[7]: True
