示例：

import base64import rsadef strkey(strk):    b_str = base64.b64decode(strk)    if len(b_str) < 162:        return False    hex_str = ‘‘    # 按位转换成16进制    for x in b_str:        h = hex(ord(x))[2:]        h = h.rjust(2, ‘0‘)        hex_str += h    # 找到模数和指数的开头结束位置    m_start = 29 * 2    e_start = 159 * 2    m_len = 128 * 2    e_len = 3 * 2    modulus = hex_str[m_start:m_start + m_len]    exponent = hex_str[e_start:e_start + e_len]    return modulus, exponentif __name__ == ‘__main__‘:    pub_str = "MIGfMA0GCSqGSIb3DQEBAQUAA4GNADCBiQKBgQDPg0O4rPQJL1O+jqJ4rBjFVNRAuDmBSoii9pYfPQBaescCVY0irkWWoLyfTT65TjvnPpOx+IfNzBTlB13qCEFm7algREoeUHjFgFNHiXJ2LK/R0+VWgXe5+EDFfbrFCPnmLKG3OcKDGQszP0VOf6VVTM1t56CpgaRMm1/+Tzd2TQIDAQAB"    modulus, exponent = strkey(pub_str)    modulus = int(modulus, 16)    exponent = int(exponent, 16)    pub_key = rsa.PublicKey(modulus, exponent)    print pub_key
