javax.crypto.BadPaddingException:解密错误

我尝试在同一个容器中的代理程序的代码,但它工作正常,但如果它们不在不同的容器上。
这是我如何加密消息:
String msg1 =Messag e从bob 1; // message
MSGBOB = cipher.doFinal(msg1.getBytes(ISO-8859-1)); // encryption
msg.setContent(new String(MSGBOB,ISO-8859-1)); //转换为字符串
这是我如何解密它:
mm = msg.getContent()。getBytes(ISO-8859-1); //收到的消息
m = new String(cipher.doFinal毫米), ISO-8859-1); //解密
使用base64编码输出加密,不要使用 new String()
,因为某些字节值将不会被正确地表示为字符串。所以当反转到字节再次不会是正确的加密值
这是我的意思:
String msg1 =来自bob 1的消息; // message
MSGBOB = cipher.doFinal(msg1.getBytes(ISO-8859-1)); // encryption
msg.setContent(Base64.encode(MSGBOB)); //转换为字符串
这是我如何解密它:
mm = Base64.decode(msg.getContent()); //收到的消息
m = new String .doFinal(毫米), ISO-8859-1); //解密
I am trying to send encrypted messages between two agents .I have a string that contains information that I convert to bytes encrypt it and then to string again to send the message. Messages are received however, at the receiving agent I get the following exception

I tried the code for agents in the same container and it works fine however, if they are on different container it doesn't.
This is how I encrypt the message:
String msg1="Message from bob 1"; // message
MSGBOB = cipher.doFinal(msg1.getBytes("ISO-8859-1")); // encryption
msg.setContent(new String (MSGBOB,"ISO-8859-1")); // conversion to string
This is how I decrypt it :
mm = msg.getContent().getBytes("ISO-8859-1");// received message
m = new String(cipher.doFinal(mm),"ISO-8859-1"); // decryption
use base64 encoding for the output of the encryption, don't use new String()
as some byte-values will not be represented correctly as string. so when reversed to bytes again it will not be the correct ciphered value
here is what i mean:
String msg1="Message from bob 1"; // message
MSGBOB = cipher.doFinal(msg1.getBytes("ISO-8859-1")); // encryption
msg.setContent(Base64.encode(MSGBOB)); // conversion to string
This is how I decrypt it :
mm = Base64.decode(msg.getContent());// received message
m = new String(cipher.doFinal(mm),"ISO-8859-1"); // decryption
