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).
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. Key sizes can...
11 Μαρ 2022 · Introduction to cryptography. Public networks such as the Internet do not provide a means of secure communication between entities. Communication over such networks is susceptible to being read or even modified by unauthorized third parties.
13 Φεβ 2024 · The .NET cryptography system implements an extensible pattern of derived class inheritance. The hierarchy is as follows: Algorithm type class, such as SymmetricAlgorithm, AsymmetricAlgorithm, or HashAlgorithm. This level is abstract.
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.
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).
