When we call a function, the local variables and parameters of the function are stored in a stack. In x86 64-bit architecture or x64, the RBP register contains the base address of the stack. And, the RSP register contains the address of the top of the stack. When we...
In this article, we will discuss registers for x86 32-bit and 64-bit architecture. Firstly, we will discuss the registers for x86 32-bit processors. After that, we will discuss the registers for x86 64-bit processors. General Purpose Registers For x86 32-bit...
Substitution-Permutation Networks (SPN) are often used to construct an iterative block cipher. In an iterative block cipher, an input plaintext block goes through several rounds. In each round, separate round keys are used. In a Substitution-Permutation Network (SPN),...
RC4 is a stream cipher. It was designed by Ron Rivest in 1987. The algorithm is well-known for its simplicity and speed in software. In our previous article, we discussed how the RC4 algorithm works. In this article, we would discuss how to implement the RC4 algorithm...
RC4 is a stream cipher that was designed by Ron Rivest in 1987. This cipher is well-known for its simplicity and speed in software. RC4 is used in many protocols like WEP, WPA, Microsoft Point-to-Point encryption, etc. It was once used in protocols like TLS also. But,...
