DES解密：java.security.InvalidKeyException: Parameters missing

DES加密时正常，解密时出错了：

java.security.InvalidKeyException: Parameters missingat com.sun.crypto.provider.CipherCore.init(CipherCore.java:469)at com.sun.crypto.provider.DESCipher.engineInit(DESCipher.java:186)at javax.crypto.Cipher.implInit(Cipher.java:805)at javax.crypto.Cipher.chooseProvider(Cipher.java:867)at javax.crypto.Cipher.init(Cipher.java:1252)at javax.crypto.Cipher.init(Cipher.java:1189)

代码如下：

public static void decrypt()
{Cipher cipher = decryptCipher = Cipher.getInstance(CIPHER_ALGORITHM);Key key = CipherDES.generateKey(CdkeyGenerator.PASSWORD);cipher.init(Cipher.DECRYPT_MODE, key);byte[] decryptedBytes = cipher.doFinal(validateBytes);
}

解决办法：

错误的参数：String CIPHER_ALGORITHM = "DES/CBC/PKCS5Padding";
正确的参数：String CIPHER_ALGORITHM = "DES/ECB/PKCS5Padding";
