PlainCrypto

Simple implementation of common cryptographic algorithms for .NET.

Currently AES(128, 192, 256-Bits), TripleDES(two or three 64-Bits keys), DES and RC2(40 to 128-Bits). More to come soon!!!

Installation

You can install the latest package directly to your project in Visual Studio via NuGet Package Manager Console using the command:

PM> Install-Package PlainCrypto

or searching via the NuGet extension for the package "PlainCrypto".

You can always download or fork this repository and include it in your own solution.

Utilization

• Create a new instance of the crypto you want to use (CryptoAES, Crypto3DES*, CryptoDES or Crypto RC2) and pass the key(s) in the constructor.

ICrypto crypto = new CryptoAES(key);

• Set an initialization vector.**

crypto.SetIV(iv)

• Proceed to encrypt or decrypt your string.

encryptedMessage = crypto.Encrypt(originalMessage);

or

decryptedMessage = crypto.Decrypt(encryptedMessage)

*Crypto3DES supports two or three key operation with the option to bundle all the keys in a single buffer.

**Setting an IV is optional for all the cryptos. By default the IV will be generated automatically at instantiation and is always regenerated after each encryption.

Technical Notes

• The mode of operation is CBC(Cipher-Block Chainnig).
• The padding mode is PKCS7.
• The IV is written/read at/from the beginning of the result.

Dependencies
