This repository contains an encryption and decryption algorithm designed to shift characters in a string by a specified key. The encryption process handles words and spaces differently, incrementing ...

The python script encrypts or decrypts a file using a password. It uses the password-key derivation function to derive a 32-byte key from a password passed as an arguement and a random 16 byte salt.

Cryptography is the art of keeping information secret and safe by transforming it into form that unintended recipients cannot understand. It makes secure data transmission over the internet possible.

This paper presents an implementation of three encryption algorithms and a comparison between them based on CPU execution time. The CPU execution time is broken down to kernel and user time. The ...

Cryptography is a discipline that requires a background in mathematics. All encryption, decryption, and signature algorithms are based on notions and theorems known in number theory, modular ...

Symmetric algorithms like AES can encrypt and decrypt data quickly, making them ideal for applications requiring real-time or bulk data processing. 2. Strength Against Brute Force Attacks ...

For example, the cryptographic algorithms in the GSM (Global System for Mobile communications) mobile-phone system rely on the use of LFSRs. An LFSR comprises a register containing a sequence of bits ...
