Car Registration #API now on #Bower


Bower is a cool front-end component manager for Javascript, CSS, and the like. We’ve just published our Car Registration API to Bower, as a component. – It’s not the recommended way to connect to our API, but just to help people out, here’s a sample.

A bower package as a simple wrapper for the Reg Check API, to use this library, run

bower install CarRegistrationAPI

Then include the scripts;

bower_components/Car Registration API/api.js

Finally call the API as follows

  lookup("Check","**your username**","**UK License Plate**",function(data){

You will need a username from Car Registration API to get started.

Asymetric Encryption in C# and #Javascript

encrypt and decrypt

Here is a scenario, where you generate RSA asymetric encryption keys in C#, use the public key to encrypt a message, then decrypt it using Javascript.

First, generate a pair of keys in C#

RSACryptoServiceProvider rsa = new RSACryptoServiceProvider(2048);
tbPublicKey.Text = rsa.ToXmlString(false); // false to get the public key
tbPrivateKey.Text = rsa.ToXmlString(true); // true to get the private key

I’ve selected a key length of 2014 bits, this gives an output cypher text of 255 bytes,  or 344 bytes when base64 encoded.

You then use code such as the following to encrypt:

static string EncryptText(string publicKey, string text)
// Convert the text to an array of bytes
UTF8Encoding byteConverter = new UTF8Encoding();
byte[] dataToEncrypt = byteConverter.GetBytes(text);

// Create a byte array to store the encrypted data in it
byte[] encryptedData;
using (RSACryptoServiceProvider rsa = new RSACryptoServiceProvider())
// Set the rsa pulic key

// Encrypt the data and store it in the encyptedData Array
// MAX 245 bytes
encryptedData = rsa.Encrypt(dataToEncrypt, false);
// Base 64 encode enctrypted data
return Convert.ToBase64String(encryptedData);

Then the following code to decrypt

static string DecryptText(string privateKey, string cyphertext)
// read the encrypted bytes from the file
byte[] dataToDecrypt = Convert.FromBase64String(cyphertext);

// Create an array to store the decrypted data in it
byte[] decryptedData;
using (RSACryptoServiceProvider rsa = new RSACryptoServiceProvider())
// Set the private key of the algorithm
decryptedData = rsa.Decrypt(dataToDecrypt, false);

// Get the string value from the decryptedData byte array
UTF8Encoding byteConverter = new UTF8Encoding();
return byteConverter.GetString(decryptedData);

Now, you may note the comment “// MAX 245 bytes”, This is important, since if you try to encrypt text over 245 bytes, the code will break. Note, I’m using UTF8 here, if you wanted to support chinese text, you’d need Unicode, which sets the max to 122

You can however, break the text into 245 byte chunks as follows; (Using a pipe char as a seperator)

static string EncryptLongText(string publicKey, string text)
var strOutput = “”;
var stringParts = Split(text, 245);
foreach(var stringPart in stringParts)
strOutput += EncryptText(publicKey, stringPart) + “|”;
return strOutput;

public static IEnumerable<string> Split(string str, int chunkSize)
if (string.IsNullOrEmpty(str) || chunkSize < 1)
throw new ArgumentException(“String can not be null or empty and chunk size should be greater than zero.”);
var chunkCount = str.Length / chunkSize + (str.Length % chunkSize != 0 ? 1 : 0);
for (var i = 0; i < chunkCount; i++)
var startIndex = i * chunkSize;
if (startIndex + chunkSize >= str.Length)
yield return str.Substring(startIndex);
yield return str.Substring(startIndex, chunkSize);

Then reverse the process with a Regex;

static string DecryptLongText(string privateKey, string text)
var strOutput = “”;
var stringParts = Regex.Split(text, @”\|”);
foreach (var stringPart in stringParts)
if (stringPart != “”) strOutput += DecryptText(privateKey, stringPart);
return strOutput;

That’s all there is to it in C#, now to turn to Javascript, you will need to look at the format of the keys;


The parts of the keys (elided with …) are in base64 format, you will need this in Hex format for Javascript, and a tool such as can do this online for you.

Then following the code example on – the values match up as follows;

Modulus: Modulus (hex): [n]

Exponent : Public exponent (hex, F4=0x10001): [e]

P: P (hex): [p]

Q: Q (hex): [q]

DP: D mod (P-1) (hex): [dmp1]

DQ: D mod (Q-1) (hex): [dmq1]

InverseQ : 1/Q mod P (hex): [coeff]

D : Private exponent (hex): [d]

The specified plex is a the current system or boot plex. #SoftRaid #Raid


If you want to break a mirrored volume in Disk Management, because you want to resize the partition where your If you want to break a mirrored volume in Disk Management, because you want to resize the partition where your operating system is installed, then you may get the following error:

The specified plex is a the current system or boot plex. [sic]

As per KB 969749, the solution is detailed as follows, I’ve just added the commands required.
From an elevated Command Prompt, type diskpart to start DiskPart.

Microsoft DiskPart version 10.0.14393.0
Copyright (C) 1999-2013 Microsoft Corporation.
On computer: xxxxxx

Use the list volume command in DiskPart to list the volumes present on the system.

DISKPART> list volume
Volume ###  Ltr  Label        Fs     Type        Size     Status     Info
———-  —  ———–  —–  ———-  ——-  ———  ——–
Volume 0     X   xxxx     NTFS   Spanned     xxxx MB  Healthy
Volume 1     X   xxxxx        NTFS   Mirror       xxx GB  Healthy    Boot
Volume 2         EFI          FAT32  Partition    xxx MB  Healthy    System
Volume 3         EFI          FAT32  Partition    xxx MB  Healthy    Hidden

Type the command select volume x to select the mirror volume, where x is the alphanumeric identifier of the mirror volume.

DISKPART> select volume 1
Volume 1 is the selected volume.

Determine the numeric identifier of the disk containing the plex you are currently booted into (“Boot Disk”) using the list disk, select disk, and detail disk commands.

DISKPART> list disk
Disk ###  Status         Size     Free     Dyn  Gpt
——–  ————-  ——-  ——-  —  —
Disk 0    Online          xxx GB  1024 KB   *    *
Disk 1    Online          xxx GB  1024 KB   *    *

DISKPART> select disk 0

Disk 0 is now the selected disk.

DISKPART> detail disk
INTEL xxxxx
Disk ID: {xxxx}
Type   : xxxx
Status : OnlinePath   : 0
Target : 0LUN ID : 0
Location Path : …..
Current Read-only State : No
Read-only  : No
Boot Disk  : Yes
DISKPART> select disk 1
Disk 1 is now the selected disk.
DISKPART> detail disk
INTEL xxxxx
Disk ID: {xxxxx}
Type   : xxxx
Status : Online
Path   : 0
Target : 0
LUN ID : 0
Location Path : …
Current Read-only State : No
Read-only  : No
Boot Disk  : No
Pagefile Disk  : Yes
Hibernation File Disk  : No
Crashdump Disk  : Yes
Clustered Disk  : No

If you try to break the disk without selecting the volume, then you get the following error:

DISKPART> break disk 1
There is no volume selected to break.Please select a dynamic mirror to break.

Use the command break disk n  to break the mirror, where n is the numeric identifier of the disk containing the mirror plex you are not currently booted from.The mirror will be broken, and both plexes will be converted to Simple volumes.

DISKPART> select volume 1
Volume 1 is the selected volume.
DISKPART> break disk 1
DiskPart successfully broke the mirror volume.

After this is done, you will have two simple volumes, rather than one mirrored volume which will be very similar in content. You can then use Disk Management to resize, the volumes, dealocate one of them, then select the boot volume and press Add Mirror to restore the Raid.

Enhance your #MSSQL Security with two keywords in C#

3d database with padlock security concept

If your database server is on a different machine to your webserver, and the SQL queries travel through the network, then they are liable to be sniffed by third parties sharing the same network.

However, if you add the words:

Encrypt=True; TrustServerCertificate=True

To your connection string then the TDS data sent from client to server will be encrypted, and impossible to sniff from the network.

You can verify the connection is secure by running the following query;

SELECT session_id, net_transport, client_net_address, local_net_address,
local_tcp_port, auth_scheme, encrypt_option
FROM sys.dm_exec_connections

According to performance tests, I found no difference between the performance of secure vs plain text secure. over a batch of 200 queries.

Detect #Phising links in user submitted urls in C#


If your website displays urls which are user-submitted, then you can use a free API by google called Safe Browsing (key required), to detect if these are phishing / malware urls – here is the code, with the Google API Key removed;

static bool IsMalware(string url)
var strRequestJson = File.ReadAllText(“requestjson.json”);
strRequestJson = strRequestJson.Replace(“*PLACEHOLDER*”, url);
WebClient wc = new WebClient();
var strurl = “;;
wc.Headers[HttpRequestHeader.ContentType] = “application/json”;
var strResult = wc.UploadString(strurl, strRequestJson);
if (strResult.Trim() == “{}”) return false;
return true;

You will also need the file requestjson.json set to copy always in the build options, with the following content;

“client”: {
“clientId”: “yourcompanyname”,
“clientVersion”: “1.5.2”
“threatInfo”: {
“platformTypes”: [ “WINDOWS” ],
“threatEntryTypes”: [ “URL” ],
“threatEntries”: [
{ “url”: “*PLACEHOLDER*” }

Get automated notifications on #WindowsUpdate using C# and #WUApiLib


If you wanted to be notified as soon as a windows update is available on your server, but you don’t want it to be installed automatically, here is a script in C# that allows you to know when an update is ready.

It requires a COM library called WUApiLib which you can add via project > References

var updateSession = new UpdateSession();
var updateSearcher = updateSession.CreateUpdateSearcher();
updateSearcher.Online = false; //set to true if you want to search online
var searchResult = updateSearcher.Search(“IsInstalled=0 And IsHidden=0 And BrowseOnly=0”);
if (searchResult.Updates.Count > 0)
Console.WriteLine(“There are updates available for installation”);
foreach (IUpdate update in searchResult.Updates)
foreach (string kbaid in update.KBArticleIDs)

Cloud Answering Machine services now available in 33 new countries

71TFmNzL5UL is a service that allows you to have a virtual answering machine attached to a real phone number practically anywhere in the world. This means that if you want to have a number that you can publish freely, without being bombarded with spam callers.

Having a virtual answering machine allows you to separate your high-priority calls from your low-priority calls, so that someone who is not in urgent need of reply, can leave a message, and you can get back to them – where your friends , family and important business partners can still contact you on your main phone line.

You can also receive text messages on your answering machine, so it can be used to activate services without disclosing your real phone number.

Up to now, we’ve had a simple pricing structure of  $15 (USD), £ 15 (GBP) or € 12 (EUR) per month, but we’ve known that certain countries have higher setup costs to provision phone lines, so we haven’t been able to offer them.

So, we’ve decided, that although most countries will still remain on the simple $15 pricing, we’ve now opened up the possibility of 33 new countries – albeit at a higher monthly cost. These premium numbers are only bookable through the website at present, but this may change in future.

Here’s the pricing table;

Country iso monthly price (USD)
United Arab Emirates AE 50
Bosnia and Herzegovina BA 84
Barbados BB 54
Benin BJ 54
Bolivia BO 50
Botswana BW 100
Belarus BY 50
Colombia CO 50
Algeria DZ 66
Ecuador EC 68
Grenada GD 54
Georgia GE 28
Ghana GH 54
Guinea GN 54
Guatemala GT 62
Jamaica JM 54
Kenya KE 32
Cayman Islands KY 58
Mali ML 76
Macau MO 140
Mauritius MU 86
Namibia NA 66
Philippines PH 50
Serbia RS 210
Singapore SG 150
Thailand TH 50
Tunisia TN 70
Trinidad and Tobago TT 54

Download complete #Twilio Pricing table in C#


Twilio offer a great service in providing international phone numbers, – and it’s the provider behind but the price varies greatly like from a $1 number in the US to a $110/month Toll free number in Bulgaria.

So, here is some code that queries the Twilio API to download all countries, and stores the pricing information in a database :

var strUrl = “;;
var wc = new WebClient();
wc.Headers[“Content-Type”] = “application/x-www-form-urlencoded”;
var credentials = Convert.ToBase64String(Encoding.ASCII.GetBytes(username + “:” + password));
wc.Headers[HttpRequestHeader.Authorization] = string.Format(
“Basic {0}”, credentials);
var strCountries = wc.DownloadString(strUrl);
var jCountries = JObject.Parse(strCountries);
foreach(var jCountry in jCountries[“countries”])
Console.WriteLine(“Downloading ” + jCountry[“country”].ToString());
var strCountryUrl = jCountry[“url”].ToString();
var strCountryJson = wc.DownloadString(strCountryUrl);
var jCountryJson = JObject.Parse(strCountryJson);
if (jCountryJson[“price_unit”].ToString() != “USD”) throw new Exception(“Should be usd!”);
foreach (var jPhoneNumber in jCountryJson[“phone_number_prices”])
var strSQL = “insert into CAMPricing (country, numberType, price) values (‘{0}’,'{1}’,{2})”;
strSQL = string.Format(strSQL,
catch(Exception ex)
Console.WriteLine(“Failed to download ” + jCountry[“country”].ToString());
