15 Δεκ 2012 · I made a simple class that handles lowercase, uppercase and numbers. It uses the StringBuilder class to make the output. To decode a string, you would use the opposite shift (if you encrypt with shift = 2, decrypt with shift = -2).
6 Ιουν 2024 · In the following sections we will discuss how to perform specific symmetric encryption algorithms, but let’s discuss what options Bouncy Castle offers. Symmetric encryption always begins by creating a cipher object. We use the CipherUtilities.GetCipher("AlgorithmName/OperationMode/PaddingStyle") method to make this cipher object. This method ...
This repository houses a powerful package designed for anyone interested in learning and implementing cryptographic algorithms in c#. With a focus on clarity, robustness, and educational value, our library provides implementations for a variety of cryptographic algorithms.
Caesar Cipher Programming Algorithm in C#. In cryptography, a Caesar cipher, also known as shift cipher, Caesar's cipher, Caesar's code or Caesar shift, is one of the simplest and most widely known encryption techniques.
5 Νοε 2016 · The Caesar Cipher involves replacing each letter of the alphabet with the letter – standing places down or up according to the key given. Suppose “M” is the plaintext and the key is given as 4, then you get the Ciphertext as the letter “Q”. In a similar way “A” is the plaintext then Ciphertext will be – “E”.
22 Οκτ 2019 · AES is a new cryptographic algorithm that can be used to protect electronic data. Specifically, AES is an iterative, symmetric-key block cipher that can use keys of 128, 192, and 256 bits, and encrypts and decrypts data in blocks of 128 bits (16 bytes).
Simple of cipher on C#, that provide encription and decription in defferent algorithms. Currently cipher provide realization of: Caesar algorithme; Trithemius algorithme; XOR Encription algorithme; Book cipher algorithme; The Knapsack cipher algorithme (based on The Knapsack Problem); .NET native algorithm implementation. DES; TripleDES; AES; RSA.
