rsa加密解密类库附示例-php&python版

早期造个对象，写了个php的rsa帮助类库，先看使用方法 $keys = RsaHelper::new_rsa_key;//生成完key之后应该记录下key值，这里省略$privkey = $keys'privkey';$pubkey = $keys'pubkey';/* $privkey = '-----BEGIN PRIVATE KEY-----MIICdwIBADANBgkqhkiG9w0BA

      妈蛋，win平台下的php protobuf折腾死我了，又改成py了，所以，python版的rsa加密辅助类来了

def new_keys():
    (bob_pub, bob_priv) = rsa.newkeys(1024)
    return {'pubkey':bob_pub.save_pkcs1(), 'privkey':bob_priv.save_pkcs1()}
 
class RsaHelper:
 
    def __init__(self, privkey, pubkey):
        self._privkey = privkey.decode('string-escape')
        self._pubkey = pubkey.decode('string-escape')
 
    def encode_priv(self, data):
        privkey = rsa.PrivateKey.load_pkcs1(self._privkey)
        crypto = rsa.encrypt(data, privkey)
        return crypto
 
    def decode_pub(self, data):
        pubkey = rsa.PublicKey.load_pkcs1(self._pubkey)
        msg = rsa.decrypt(data, pubkey)
        return msg
 
    def decode_priv(self, data):
        privkey = rsa.PrivateKey.load_pkcs1(self._privkey)
        msg = rsa.decrypt(data, privkey)
        return msg
 
    def encode_pub(self, data):
        pubkey = rsa.PublicKey.load_pkcs1(self._pubkey)
        crypto = rsa.encrypt(data, pubkey)
        return crypto
