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;
}
下面是我自己修改的,也是网上找的工具类,比较复杂…
