base64, encryption and decryption, fusion encryption, docking

String data0 = new String(Base64.encode(bo.getPaymentResult().getBytes(("GBK"))));
String data1 = new String(Base64.decode(data0.toCharArray()),"GBK");

/ / Pay attention to the encoding format, pay attention to the encryption, the decryption is the class in the same jar,
//Encryption in the fusion, decryption 1, the public and private keys of both parties are the same, 2, the point used for encryption cannot be different
