Java - Encoding message to String












0














I'm trying to implement my own version of authorization for HTTP requests. Now I'm facing a problem that I don't know how to resolve.



As shown in code below, I'm encrypting String message using RSA algorithm. But the problem is that as a result I'm getting object of class SealedObject. I need to have the possibility to use this encrypted string as header - for now using REST client like Postman. So, my question is: How can I parse SealedObject to String? Or what should I do to encrypt the message to String? Is this even possible?



KeyPairGenerator kpg = KeyPairGenerator.getInstance("RSA");
KeyPair keyPair = kpg.generateKeyPair();

String message = "Secret message";

Cipher cipher = Cipher.getInstance("RSA");
cipher.init(Cipher.ENCRYPT_MODE, keyPair.getPublic());

SealedObject encryptedMessage = new SealedObject(message, cipher);


Thank you in advance :)

the first thing that comes to mind is:



SealedObject is a Serializable Object which means you can convert it to bytes and then transform it to String using Base64:
something like this:



ByteArrayOutputStream bos = new ByteArrayOutputStream();
ObjectOutput out = null;
try {
out = new ObjectOutputStream(bos);
out.writeObject(sealedObject);
out.flush();
byte yourBytes = bos.toByteArray();
String base64StringHeader = Base64.encodeBase64String(yourBytes);
} finally {
try {
bos.close();
} catch (IOException ex) {
// ignore close exception
}
}


and then when you receive your request do something like this:



byte backToBytes = Base64.decodeBase64(base64StringHeader);
ByteArrayInputStream bis = new ByteArrayInputStream(backToBytes);
ObjectInput in = null;
try {
in = new ObjectInputStream(bis);
SealedObject = in.readObject();
...
} finally {
try {
if (in != null) {
in.close();
}
} catch (IOException ex) {
// ignore close exception
}


}
