JAVA ASE 默认随机 sha1 key加密-526互联

使用原始的方法

public static String EncryptEncode(String content, String... key) throws Exception {
        String encryptKey = "audaque2018";
        KeyGenerator keyGenerator = KeyGenerator.getInstance("AES");
        SecureRandom random = SecureRandom.getInstance("SHA1PRNG");
        random.setSeed(encryptKey.getBytes());
        keyGenerator.init(128, random);
        SecretKey originalKey = keyGenerator.generateKey();
        byte[] rawByte = originalKey.getEncoded();
        SecretKey secretKey = new SecretKeySpec(rawByte, "AES");
        Cipher cipher = Cipher.getInstance("AES"); // AES/ECB/PKCS5Padding
        cipher.init(1, secretKey);
        byte[] byteEncode = content.getBytes("utf-8");
        byte[] bytesAes = cipher.doFinal(byteEncode);
        return new String((new BASE64Encoder()).encode(bytesAes));
    }

    public static String DecryptDecode(String content, String... key) throws Exception {
        String encryptKey = "audaque2018";
        KeyGenerator keyGenerator = KeyGenerator.getInstance("AES");
        SecureRandom random = SecureRandom.getInstance("SHA1PRNG");
        random.setSeed(encryptKey.getBytes());
        keyGenerator.init(128, random);
        SecretKey originalKey = keyGenerator.generateKey();
        byte[] byteArray = originalKey.getEncoded();
        SecretKey secretKey = new SecretKeySpec(byteArray, "AES");
        Cipher cipher = Cipher.getInstance("AES");
        cipher.init(2, secretKey);
        byte[] byteContent = (new BASE64Decoder()).decodeBuffer(content);
        byte[] byteEncode = cipher.doFinal(byteContent);
        return new String(byteEncode, "utf-8");
    }

使用 hutools

 public static String invokeEncryptEncode(String content, String... key) throws NoSuchAlgorithmException {
        String encryptKey = "audaque2018";
        SecureRandom random = SecureRandom.getInstance("SHA1PRNG");
        random.setSeed(encryptKey.getBytes());
        byte[] keyBytes = new byte[16];
        random.nextBytes(keyBytes);
        AES aes = SecureUtil.aes(keyBytes);
        byte[] encryptedBytes = aes.encrypt(content.getBytes());
        String resultEncode = Base64Encoder.encode(encryptedBytes);

        return resultEncode;
    }

    public static String invokeDecryptDecode(String encryptedContent, String... key) throws NoSuchAlgorithmException {
        String encryptKey = "audaque2018";
        SecureRandom random = SecureRandom.getInstance("SHA1PRNG");
        random.setSeed(encryptKey.getBytes());
        byte[] keyBytes = new byte[16];
        random.nextBytes(keyBytes);
        AES aes = SecureUtil.aes(keyBytes);
        byte[] encryptedBytes = Base64Decoder.decode(encryptedContent);
        byte[] decryptedBytes = aes.decrypt(encryptedBytes);
        return new String(decryptedBytes);
    }
