Python 调用 Java 生成的 RSA 私钥加密结果不一样

Java 代码

public static String encrypt(String paramString)throws Exception

各位老爷给看看，是哪里姿势不对

[zeiyso]

这是特性…… random padding
https://en.wikipedia.org/wiki/Padding_(cryptography)

[rogerchen]

为什么 java 里边不对 privatekey 的 b64 表示解码， python 不都先 decode 了么

[iamxiaoq]

@rogerchen encryptByPrivateKey 这个方法里面会对 primarykey 进行 base64 解码

[iamxiaoq]

@zeiyso 英文实在太弱了，老哥能再提示多一点吗？

[zeiyso]

看这个不错 http://blog.csdn.net/defonds/article/details/42775183

[iamxiaoq]

@zeiyso 老哥稳，读了后面那篇已经明白为什么了，下一步就看怎么解决了，灰常感谢！！

不需要关注是否一致，只需要关注能否互操作

[iamxiaoq]

@julyclyde 服务器只接受 Java 加密出来的密文， python 加密的密文不接受。

[julyclyde]

@iamxiaoq 好奇怪……

您好 遇到同样的问题 .. 请问怎么解决的呢？
