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).
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.
11 Φεβ 2010 · Are you trying to do something like a Caesar cipher? (i.e. take every letter and shift it a certain number of letters to the left or right?) If so, you will want to work with individual characters on your string. There's a datatype char that allows this, and you can do arithmetic operations.
The encryption of Caesar cipher can be represented using modular arithmetic by first transforming the letters into numbers, according to the scheme, A = 0, B = 1,..., Z = 25. Encryption of a letter x by a shift n can be described mathematically as, Decryption is performed similarly, Example:
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”.
26 Μαρ 2024 · AES (Advanced Encryption Standard) is a symmetric block cipher algorithm that encrypts fixed-length blocks of data (128 bits). AES uses the same key to encrypt and decrypt data.
15 Σεπ 2022 · The Caesar cipher is a substitution cipher that shifts letter positions. It is similar to ROT13. The shift value can be kept secret to make the cipher harder to break.
