Input length must be multiple of 8 when decrypting with padded cipher

Des密码加密报错：Input length must be multiple of 8 when decrypting with padded cipher

错误原因：

判断加密代码上一句执行的是否是解密
我的是先执行解密，然后加密，报的这个错误，原本是直接加密就好的
针对文件加密多写了一个字符

附上加密解密代码：
解密：直接调用DesUtil的decrypt方法即可

// DES解密key,限定24位
String DES_KEY = "WfJTKO9S4eLkrPz2JKrAnzdb";
// DES解密iv,限定8位
String DES_IV = "D076D35C";
String pwd = DesUtil.decrypt(userDto.getPsw(), ContentSecurityConstants.DES_KEY,ContentSecurityConstants.DES_IV);

加密：

生成盐值

 public static final Integer SALT_SIZE = 8;/*** 生成随机的Byte[]作为salt.* * @param numBytes*            byte数组的大小*/public static byte[] generateSalt(int numBytes) {Validate.isTrue(numBytes > 0, "numBytes argument must be a positive integer (1 or larger)", numBytes);byte[] bytes = new byte[numBytes];random.nextBytes(bytes);return bytes;}public static byte[] generateSaltFix() {return generateSalt(SALT_SIZE);}// 盐值byte[] salt = generateSaltFix();

PasswdService接口类

 /*** 密码* @param saltBytes 混淆码数组* @param rawPass 明文密码* @return 密码*/public String entryptPassword(byte[] saltBytes,String rawPass);

PasswdServiceImpl接口实现类

 @Overridepublic String entryptPassword(byte[] saltBytes, String rawPass) {String encPass = CredentialsDigest.digest(rawPass, saltBytes);return encPass;}

CredentialsDigest证书加密接口

 public interface CredentialsDigest {/*** 散列生成摘要* @Title: digest  * @param plainCredentials 密码明文* @param salt 混淆码数组* @return: String*/public String digest(String plainCredentials, byte[] salt);}

CredentialsDigest证书加密抽象实现类

 /*** Hash证书加密**/public abstract class AbstractHashCredentialsDigest implements CredentialsDigest {public static final int HASH_INTERATIONS = 1024;@Overridepublic String digest(String plainCredentials, byte[] salt) {if (StringUtils.isBlank(plainCredentials)) {return null;}byte[] hashPassword = digest(Cryptos.utf8encode(plainCredentials), salt);return Encodes.encodeHex(hashPassword);}/*** 需要实现加密转换* @Title: digest  * @param input 输入字节数组* @param salt 混淆字节数组* @return: byte[]*/protected abstract byte[] digest(byte[] input, byte[] salt);}

不同加密方式（当前使用的是SHA1密码加密）
（1） SHA1证书加密

 public class Sha1CredentialsDigest extends AbstractHashCredentialsDigest {@Overrideprotected byte[] digest(byte[] input, byte[] salt) {return Digests.sha1(input, salt, HASH_INTERATIONS);}}

（2） SHA256证书加密

 /*** SHA256证书加密*/public class Sha256CredentialsDigest extends AbstractHashCredentialsDigest implementsCredentialsDigest {@Overrideprotected byte[] digest(byte[] input, byte[] salt) {return Digests.sha256(input, salt, HASH_INTERATIONS);}}

（3） SHA512加密方式

 /*** SHA512证书加密*/public class Sha512CredentialsDigest extends AbstractHashCredentialsDigest implementsCredentialsDigest {@Overrideprotected byte[] digest(byte[] input, byte[] salt) {return Digests.sha512(input, salt, HASH_INTERATIONS);}}
