Question

我有一段java代码示例，用aes + SHA1PRNG解码字符串，这里是：

public static String decodeParam(String content,String key){
    String decodeParams = "";
    byte[] decodeByte =  parseHexStr2Byte(content);
    try {
        decodeParams = deCrypt(decodeByte,key);
    } catch (Exception e) {
        e.printStackTrace();
    }
    return decodeParams;
}

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;
}

public static String deCrypt (byte[] src,String strKey) throws Exception{
    KeyGenerator keygen;
    SecretKey desKey;
    Cipher c;
    byte[] cByte;

    keygen = KeyGenerator.getInstance("AES");
    SecureRandom secureRandom = SecureRandom.getInstance("SHA1PRNG");
    secureRandom.setSeed(strKey.getBytes());
    keygen.init(128, secureRandom);

    SecretKeySpec securekey = new SecretKeySpec(strKey.getBytes(), "AES");

    desKey = keygen.generateKey();
    c = Cipher.getInstance("AES");

    c.init(Cipher.DECRYPT_MODE, desKey);


    cByte = c.doFinal(src);

    return new String(cByte,"UTF-8");
}

这是测试功能：

public static void main(String args[]){
    String hw = decodeParam("C6F8437E9D868ED99D8CAD8F6C417858","password");
    System.out.println(hw); // hello world
}

但是我想在node.js中执行此操作，我发现它们在node.js中具有完全不同的名称。如何在 C6F8437E9D868ED99D8CAD8F6C417858 中将hello world解码为Node.js？

Node.js解码aes + SHA1PRNG？
