问题描述

(C#转JAVA)DES加密解密问题 。带入整8B加密数据， JAVA写的总是比C#写的多出来8B 1C

C#

private byte[] CSharpEncryptByte(byte[] InputByte byte[] sKey)

{

   DESCryptoServiceProvider DES = new DESCryptoServiceProvider();   DES.Padding = PaddingMode.Zeros;   DES.Key = sKey;   DES.IV = new byte[] { 0 0 0 0 0 0 0 0 };   ICryptoTransform desencrypt = DES.CreateEncryptor();   byte[] result = desencrypt.TransformFinalBlock(InputByte 0 InputByte.Length);   return result;

}

JAVA

public static byte[] JavaEncryptByte(byte[] InputByte byte[] bKey)
throws Exception
{
byte[] ivdata = new byte[]{0 0 0 0 0 0 0 0};
IvParameterSpec spec = new IvParameterSpec(ivdata);
SecretKeySpec keySpec = new SecretKeySpec(bKeyDES"");
Cipher cipherex = Cipher.getInstance(""DES/CBC/ZeroBytePadding"");
cipherex.init(Cipher.ENCRYPT_MODE keySpec spec);
byte[] encdata = cipherex.doFinal(InputByte 0 InputByte.length);
return encdata;
}

解决方案

试试看ECB模式，DES/ECB/ZeroBytePadding
