The foll

Answer 1

You could turn it into a string with some encoding, like:

encryptedData =   encryptCipher.doFinal(strToEncrypt.getBytes());
String s = new String(encryptedData, "Base-64");

Using the same standardized encoding, both C# and Java should be able to reconstruct each others encrypted data from that string.
