Problems found, the server directly to decrypt the key operation, the. Net must first be converted to Base64, in decoding, otherwise the decoding error, lead to IV vector byte array into 24, result in abnormal or encryption failure,
For the have good way to solve this problem:

The key value in the Java in the picture is the content to. Net and Java different little elder brother encryption results
