java的aes加解密，js？

Question

目前有java有加密和解密代码，因为不了解AES，js这块代码不知道如何写，试了好多都匹配不上java的加密和解密的值，有大亻老的看看吗？

// 加密
public static String encrypt(String key, String cleartext) {
        try {
            byte[] raw = InsecureSHA1PRNGKeyDerivator.deriveInsecureKey(key.getBytes(), 32);
            SecretKeySpec skeySpec = new SecretKeySpec(raw, AES);
            Cipher cipher = Cipher.getInstance("AES");
            cipher.init(Cipher.ENCRYPT_MODE, skeySpec);
            byte[] encrypted = cipher.doFinal(cleartext.getBytes());
            return parseByte2HexStr(encrypted);
        } catch (Exception e) {
            e.printStackTrace();
        }
        return "";
}

public static String parseByte2HexStr(byte buf[]) {
        StringBuilder sb = new StringBuilder();
        for (int i = 0; i < buf.length; i++) {
            String hex = Integer.toHexString(buf[i] & 0xFF);
            if (hex.length() == 1) {
                hex = '0' + hex;
            }
            sb.append(hex.toUpperCase());
        }
        return sb.toString();
}

// 解密
    public static String decrypt1(String key, String encrypted) {
        try {
            byte[] enc = parseHexStr2Byte(encrypted);
            byte[] raw = InsecureSHA1PRNGKeyDerivator.deriveInsecureKey(key.getBytes(), 32);
            SecretKeySpec skeySpec = new SecretKeySpec(raw, AES);
            Cipher cipher = Cipher.getInstance(AES);
            cipher.init(Cipher.DECRYPT_MODE, skeySpec);
            byte[] decrypted = cipher.doFinal(enc);
            return new String(decrypted);
        } catch (Exception e) {
            e.printStackTrace();
        }
        return null;
    }

public static byte[] parseHexStr2Byte(String hexStr) {
        if (hexStr.length() < 1) {
            return null;
        }
        byte[] result = new byte[hexStr.length() / 2];
        for (int i = 0; i < hexStr.length() / 2; i++) {
            int high = Integer.parseInt(hexStr.substring(i * 2, i * 2 + 1), 16);
            int low = Integer.parseInt(hexStr.substring(i * 2 + 1, i * 2 + 2),16);
            result[i] = (byte) (high * 16 + low);
        }
        return result;
}

可以使用 CryptoJS 库实现 AES 加密/解密在 JavaScript 中。下面是一段实现 AES 加密/解密的 JavaScript 代码：

// AES 加密
function encryptAES(data, key) {
    var ciphertext = CryptoJS.AES.encrypt(data, key);
    return ciphertext.toString();
}

// AES 解密
function decryptAES(ciphertext, key) {
    var data = CryptoJS.AES.decrypt(ciphertext, key);
    return data.toString(CryptoJS.enc.Utf8);
}

// 测试加密/解密
var data = "Hello World";
var key = "1234567890123456";
var ciphertext = encryptAES(data, key);
var decryptedData = decryptAES(ciphertext, key);

console.log("加密前的数据：" + data);
console.log("加密后的数据：" + ciphertext);
console.log("解密后的数据：" + decryptedData);
