javax.crypto.BadPaddingException: Given final block not properly padded. Suc

本文主要是介绍javax.crypto.BadPaddingException: Given final block not properly padded. Suc，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

在在进行token加密解密的时候报错:

javax.crypto.BadPaddingException: Given final block not properly padded. Suc

然后百度一下:
对着这哥们的修改一波:

主要就是修改加密部分:
在这里插入图片描述
在linux上面错误部分:

private Key initKeyForAES(String key) throws NoSuchAlgorithmException {if (null == key || key.length() == 0) {throw new NullPointerException("key not is null");}SecretKeySpec key2 = null;try {KeyGenerator kgen = KeyGenerator.getInstance("AES");kgen.init(128, new SecureRandom(key.getBytes()));SecretKey secretKey = kgen.generateKey();byte[] enCodeFormat = secretKey.getEncoded();key2 = new SecretKeySpec(enCodeFormat, "AES");} catch (NoSuchAlgorithmException ex) {throw new NoSuchAlgorithmException();}return key2;}

修改后部分:

private Key initKeyForAES(String key) throws NoSuchAlgorithmException {if (null == key || key.length() == 0) {throw new NullPointerException("key not is null");}SecretKeySpec key2 = null;SecureRandom random = SecureRandom.getInstance("SHA1PRNG");random.setSeed(key.getBytes());try {KeyGenerator kgen = KeyGenerator.getInstance("AES");kgen.init(128, random);SecretKey secretKey = kgen.generateKey();byte[] enCodeFormat = secretKey.getEncoded();key2 = new SecretKeySpec(enCodeFormat, "AES");} catch (NoSuchAlgorithmException ex) {throw new NoSuchAlgorithmException();}return key2;}
