RSA解密过程中遇到的报错 报错：javax.crypto.BadPaddingException: Blocktype mismatch

报错：org.bouncycastle.crypto.DataLengthException: input too large for RSA cipher.

问题所在：没留意被解密的报文是“content=XXX”，应该是“XXX”的

解决办法：把接收的报文过滤掉“content=”就行；

报错：javax.crypto.BadPaddingException: Blocktype mismatch

问题所在：接口双方加解密使用的secrutity provider不一样不兼容，报错中的padding是关键提示；

解决办法：把代码中Cipher cipher = Cipher.getInstance("RSA");

改成Cipher cipher = Cipher.getInstance("RSA/None/PKCS1Padding");
