Run or deploy Go (Golang) project code in IIS as web server

 Hi folks,

Today we are going to see, how we can run or deploy the Go (Golang) project in IIS.

Development

1. Create your Golang project with web APIs
2. Build the Go project
3. Go build
4. Result will be an .exe file
5. Create a web.config file
6. Update the following content

<?xml version="1.0" encoding="utf-8"?>

<configuration>

    <system.webServer>

        <handlers>

            <add name="aspNetCore" path="*" verb="*" modules="AspNetCoreModule" resourceType="Unspecified" />

        </handlers>

        <aspNetCore processPath=".\<<GoProject>>.exe" />

    </system.webServer>

</configuration>

Deployment 

1. Place the <<GoProject.exe>> and web.config in IIS server accessible folder.
2. Open IIS
3. Create a new website
4. Enter the web app details with port different from the project internal port
5. Create or choose pool with .NET CLR version as "No managed code"
6. The configured website looks like below
7. 
8. After starting the website, user should be able to access the APIs

Hope, this information helps you to deploy the GOlang project in IIS.

Generate or Create ECDSA - Elliptic Curve Digital Signature Algorithm Keys using OpenSSL in Windows

 Hi folks,

Today we will see how we can create ECDSA (Elliptic Curve Digital Signature Algorithm) Keys

Pre-requisites

OpenSSL

Add openssl bin directory to the environment PATH variable 

Generate Keys

Open Powershell and execute the following commands

1. Get the ECC curves list

openssl ecparam -list_curves

2. Generate a private key using your chosen curve

openssl ecparam -name prime256v1 -genkey -noout -out private-key.pem

3. Generate public key from the private key

openssl ec -in private-key.pem -pubout -out public-key.pem

4. Create a self-signed certificate with 1 year validity

openssl req -new -x509 -config "<opensslDirPath>/share/openssl.cnf" -key private-key.pem -out cert.pem -days 360

5. Convert pem to pfx

get-content private-key.pem, cert.pem | out-file cert-with-private-key

openssl pkcs12 -export -inkey private-key.pem -in cert-with-private-key -out cert.pfx

 Note: Enter the password when prompted (Optional)

Now, you can install the PFX file and check the certificate properties and make use of it.

Download Chrome Extension for offline Installation

 Hi folks,

I tried to use my extension for offline usage for a VM based PC browser which doesn't have internet to download the extension.

So, I have come up with this approach where you can download the chrome extension (.crx) file.

Find the extension ID

Sample browser extension URL in chrome web store is below

https://chrome.google.com/webstore/detail/previous-next-page/fmichikmgflpgibapdhepmodjdjemmda

Last word is the extension ID (fmichikmgflpgibapdhepmodjdjemmda)

Download the extension file

Browser: Use Mozilla Firefox or other browser but not chrome

Syntax

https://clients2.google.com/service/update2/crx?response=redirect&prodversion=<<browser_version>>&acceptformat=crx2,crx3&x=id%3D<<extensionID>>%26uc

Example

https://clients2.google.com/service/update2/crx?response=redirect&prodversion=85.0.4183.121&acceptformat=crx2,crx3&x=id%3Dfmichikmgflpgibapdhepmodjdjemmda%26uc

Install the extension

1. Copy the .crx file to your offline computer
2. Open Chrome browser
3. Navigate to chrome://extensions
4. Enable developer mode
5. Drag and drop the .crx file

Hope you will be able to use the offline extensions in chrome.

Convert JSON file to CSV with Python

 Hi folks,

Today I will explain the code to implement the Json2CSV conversion.

Make sure you have valid JSON file with an array of objects.

Sample:

"Users":[

{"id": 1, "Name": "Suresh Raju", "Age": 35},

{"id":2, "Name": "PSR", "Age": 34}

]

I have chosen Python language to convert because of inbuilt library support for json and csv and command line execution with Notepad++ as editor.
