三重 DES 加密字符串生成“\n”
Triple DES encryption string generates "\n"
加密字符串时,在字符串末尾生成'\n'
。
这就是我进行加密的方式
public static String encrypt(String plainText) throws Exception {
byte[] tdesKeyData = Consts.getSecretKey().getBytes();
byte[] myIV = Consts.getInitializationVector().getBytes();
SecretKeySpec myKey = new SecretKeySpec(tdesKeyData, "DES");
IvParameterSpec ivspec = new IvParameterSpec(myIV);
Cipher cipher = Cipher.getInstance("DESede/CBC/PKCS7Padding");
cipher.init(Cipher.ENCRYPT_MODE, myKey, ivspec);
byte[] plainTextBytes = plainText.getBytes("UTF-8");
byte[] buf = cipher.doFinal(plainTextBytes);
byte[] base64Bytes = Base64.encode(buf, Base64.DEFAULT);
String base64EncryptedString = new String(base64Bytes);
return base64EncryptedString;
}
拜托,有人指导我,我在这里做错了什么?提前致谢。
