4.5 python加密

备注：如果使用python3.* 在Windows进行开发，不要用windows系统安装M2Crypto，基本不会安装成功。可以使用vmware workstation或者virtualbox安装liunx或者Mac OS系统进行开发。

Python 2.*版本

import base64
import M2Crypto
class RsaUtil:
    @staticmethod
    def encrypt(digest, private_key):
        digest=base64.b64encode(digest)
        result = ""
        while (len(digest) > 117):
            some = digest[0:117]
            digest = digest[117:]
            result += private_key.private_encrypt(some, M2Crypto.RSA.pkcs1_padding).encode("hex")
        result += private_key.private_encrypt(digest, M2Crypto.RSA.pkcs1_padding).encode("hex")
        return result
if __name__ == "__main__":
    private_key = M2Crypto.RSA.load_key('8000013189_pri.pem')
    result= RsaUtil.encrypt("123456",private_key)
    print result

Python 3.*版本

import base64
import M2Crypto
class RsaUtil:
    private_key = M2Crypto.RSA.load_key('8000013189_test.pem')
    @staticmethod
    def encrypt(digest, private_key):
        digest=base64.b64encode(digest.encode('utf-8'))
        result = ""
        while (len(digest) > 117):
            some = digest[0:117]
            digest = digest[117:]
            result += private_key.private_encrypt(some, M2Crypto.RSA.pkcs1_padding).hex()
        result += private_key.private_encrypt(digest, M2Crypto.RSA.pkcs1_padding).hex()
        return result
if __name__ == "__main__":
    rsaUtil=RsaUtil()
    result=rsaUtil.encrypt("123456",RsaUtil.private_key)
    print(result)
