15 Δεκ 2012 · To decode a string, you would use the opposite shift (if you encrypt with shift = 2, decrypt with shift = -2). I'm also kind of new to C# and come from a C++ background, but I hope this approach works for you or makes it clear how to approach it.
Add the package to your C# project as a dependency. Explore the provided implementations, comments, and test cases to gain a deeper understanding of cryptography and cryptanalysis. Utilize the library in your projects for secure encryption, decryption, and analysis tasks.
The Confederate Cipher Disk is made of brass. The outer disk has a diameter of approx. 2 1/4 inch, whilst the inner disk measures approx 1 1/2 inch. On each of the disks, the alphabet is written out clockwise in the usual order (A-Z).
6 Νοε 2015 · I'm brand new to C# and I've started to make a cipher decryption program. The code works and runs fine, apart from the odd exception. I'm just looking for ways to improve my code and make more efficient. static void Main(string[] args)
15 Απρ 2021 · Confederate generals used Vigenère regularly during the civil war, and their messages were routinely cryptanalzed by Union officers. Figure 21.3: Confederate Cipher Disk for implementing the Vigenère cipher.
24 Αυγ 2018 · This chapter looks at the cipher systems used by both the Union and Confederate sides during the American Civil War. It also presents a description of the biggest cryptanalytic breakthrough of the nineteenth century, the breaking of the unbreakable cipher, the Vigenère.
