TLS (Transport Layer Security) is a security protocol that is used to establish a secure communication channel between two systems, typically a web server and a web client (such as a web browser). Here is a high-level overview of how the TLS Handshake works:

C++ – Strategy Design Pattern – Behavioral Design Pattern
The Strategy design pattern is a behavioral design pattern that defines a family of algorithms, encapsulates each one, and makes them interchangeable. It lets the algorithm vary independently from clients that use it. Here’s an example of how the Strategy pattern might be implemented in C++: In this example, the Strategy class is an interface… Continue reading
TLS 1.2 support with C# windows
Recently I ran into an issue where my client failed to connect to our windows software after they upgraded to TLS 1.2. Reason being our application was supporting tls version < 1.2 because of .Net 4.5 . Since TLS standards keep developing and improving. At the moment TLS 1.2 is a latest encryption standard powering… Continue reading
Calculate size of drive in C# – How to find directory drive?
In this post, we will be discussing how to find the directory drive and the size of drive in C#. This can be useful where application might want to check for drive size or remaining size of drive before getting started. Below is the snippet of implementation: To get the drive information in C#, one… Continue reading
Difference between new and malloc
malloc() returns a void pointer it is necessary to explicitly typecast it into an appropriate type of pointer. This gets completely avoided when using new operator. E.g int *ptr1 = (int *)malloc(sizeof(int)); float *ptr2 = (float *)malloc(sizeof(float)); ExampleClass *ptr3 = (ExampleClass*)malloc(sizeof(sample)); Here ExampleClass is a user defined class. int *ptr1 = new int; int *ptr2… Continue reading
Bind and placeholders in C++
Bind() introduced in c++11 allows you to bind parameters of a callable in a flexible way. Youcan bind parameters to fixed values, and you can even rearrange parameters in a different order. bind(function pointer, bound arguments) For example, let add3 be a function that takes 3 integer arguments and returns an int that is the… Continue reading
Program to find best possible denomination of input money
In this program, we will be finding possible denomination of money input from user. In this case we are assuming denomination as 1,5,10,25. For example if input money is 65 then denomination will be 25*2,10*1,5*1. Since we are trying to get best possible denomination such that we have least coins, so will store the denomination… Continue reading
