Java免密码调用Windows远程桌面RDP

1、计算用户密码密文的两种算法

(1)引入所需的依赖

    net.java.dev.jna
    jna-platform
    4.1.0



    cn.hutool
    hutool-all
    5.7.18

(2)加密与解密算法实现

public static String cryptRdpPassword0(String password) {
    WinCrypt.DATA_BLOB pDataIn = new WinCrypt.DATA_BLOB(password.getBytes(StandardCharsets.UTF_16LE));
    WinCrypt.DATA_BLOB pDataEncrypted = new WinCrypt.DATA_BLOB();
    Crypt32.INSTANCE.CryptProtectData(pDataIn, "psw", null, null, null, 1, pDataEncrypted);
    StringBuffer epwsb = new StringBuffer();
    byte[] pwdBytes = new byte[pDataEncrypted.cbData];
    pwdBytes = pDataEncrypted.getData();
    Formatter formatter = new Formatter(epwsb);
    for (final byte b : pwdBytes) {
        formatter.format("%02X", b);
    }
    return epwsb.toString();
}
public static String cryptRdpPassword(String password) {
    return toHexString(Crypt32Util.cryptProtectData(password.getBytes(StandardCharsets.UTF_16LE)));
}
public static String toHexString(byte[] bytes) {
    StringBuilder sb = new StringBuilder();
    Formatter formatter = new Formatter(sb);
    for (byte b : bytes) {
        formatter.format("%02X", b);
    }
    formatter.close();
    return sb.toString();
}
public static String decodeRdpPassword(String password) {
    try {
        return new String(Crypt32Util.cryptUnprotectData(toBytes(password)), "UTF-16LE");
    } catch (Exception e1) {
        e1.printStackTrace();
        return "ERROR";
    }
}
public static byte[] toBytes(String str) {// 去掉0x以后,转整数再转型成字节
    if (str == null || str.trim().equals("")) {
        return new byte[0];
    }
    byte[] bytes = new byte[str.length() / 2];
    for (int i = 0; i < str.length() / 2; i++) {
        String subStr = str.substring(i * 2, i * 2 + 2);
        bytes[i] = (byte) Integer.parseInt(subStr, 16);
    }
    return bytes;
}

2、java调用cmd命令

public static boolean cmd(String command) {
    boolean flag = false;
    try {
        Runtime.getRuntime().exec("cmd.exe /c " + command);
        flag = true;
    } catch (Exception e) {
        e.printStackTrace();
    }
    return flag;
}

3、动态生成rdp文件供调用

public static boolean getMstsc(String ip, int port, String username, String password) {
    File tempFile = new File("temp.rdp");
    ArrayList list = new ArrayList<>();
    list.add("full address:s:" + ip + ":" + port);
    list.add("username:s:" + username);
    list.add("password 51:b:" + cryptRdpPassword(password));
    list.add("drivestoredirect:s:*");
    list.add("screen mode id:i:1");
    list.add("use multimon:i:0");
    list.add("desktopwidth:i:1920");
    list.add("desktopheight:i:1080");
    list.add("session bpp:i:32");
    list.add("winposstr:s:0,1,0,30,1680,1032");
    list.add("compression:i:1");
    list.add("keyboardhook:i:2");
    list.add("audiocapturemode:i:0");
    list.add("videoplaybackmode:i:1");
    list.add("connection type:i:7");
    list.add("networkautodetect:i:1");
    list.add("bandwidthautodetect:i:1");
    list.add("displayconnectionbar:i:1");
    list.add("enableworkspacereconnect:i:0");
    list.add("disable wallpaper:i:0");
    list.add("allow font smoothing:i:0");
    list.add("allow desktop composition:i:0");
    list.add("disable full window drag:i:1");
    list.add("disable menu anims:i:1");
    list.add("disable themes:i:0");
    list.add("disable cursor setting:i:0");
    list.add("bitmapcachepersistenable:i:1");
    list.add("audiomode:i:0");
    list.add("redirectprinters:i:1");
    list.add("redirectcomports:i:0");
    list.add("redirectsmartcards:i:1");
    list.add("redirectclipboard:i:1");
    list.add("redirectposdevices:i:0");
    list.add("autoreconnection enabled:i:1");
    list.add("authentication level:i:2");
    list.add("prompt for credentials:i:0");
    list.add("negotiate security layer:i:1");
    list.add("remoteapplicationmode:i:0");
    list.add("alternate shell:s:");
    list.add("shell working directory:s:");
    list.add("gatewayhostname:s:");
    list.add("gatewayusagemethod:i:4");
    list.add("gatewaycredentialssource:i:4");
    list.add("gatewayprofileusagemethod:i:0");
    list.add("promptcredentialonce:i:0");
    list.add("gatewaybrokeringtype:i:0");
    list.add("use redirection server name:i:0");
    list.add("rdgiskdcproxy:i:0");
    list.add("kdcproxyname:s:");
    list.add("redirectlocation:i:0");
    FileUtil.writeLines(list, tempFile, CharsetUtil.UTF_8);
    return cmd("mstsc temp.rdp");
}
