推荐答案

public class AESCrypt
{
    private static final String ALGORITHM = "AES";
    private static final String KEY = "1Hbfh667adfDEJ78";

    public static String encrypt(String value) throws Exception
    {
        Key key = generateKey();
        Cipher cipher = Cipher.getInstance(AESCrypt.ALGORITHM);
        cipher.init(Cipher.ENCRYPT_MODE, key);
        byte [] encryptedByteValue = cipher.doFinal(value.getBytes("utf-8"));
        String encryptedValue64 = Base64.encodeToString(encryptedByteValue, Base64.DEFAULT);
        return encryptedValue64;

    }

    public static String decrypt(String value) throws Exception
    {
        Key key = generateKey();
        Cipher cipher = Cipher.getInstance(AESCrypt.ALGORITHM);
        cipher.init(Cipher.DECRYPT_MODE, key);
        byte[] decryptedValue64 = Base64.decode(value, Base64.DEFAULT);
        byte [] decryptedByteValue = cipher.doFinal(decryptedValue64);
        String decryptedValue = new String(decryptedByteValue,"utf-8");
        return decryptedValue;

    }

    private static Key generateKey() throws Exception
    {
        Key key = new SecretKeySpec(AESCrypt.KEY.getBytes(),AESCrypt.ALGORITHM);
        return key;
    }
}
