RJCrypt - Library

AES implementation of symmetric key encryption Rijndael using

Using

Declaring the main class

RJCrypt rj = new RJCrypt();

Encrypt a string using Rijndael AES 256-bit

string password = "eUCX6V54eTr?C8M";  // The password to encrypt the data with
string plaintext = "Text"; // The string to encrypt

// Encrypt the string
string ciphertext = rj.Encrypt(plaintext, password, RJCrypt.Common.KeySize.Aes256);

// Decrypt the string
plaintext = rj.Decrypt(ciphertext, password, RJCrypt.Common.KeySize.Aes256);

Encrypt a string using Authenticated Encryption (AE)

string password = "eUCX6V54eTr?C8M";  // The password to encrypt the data with
string plaintext = "Text"; // The string to encrypt

// Encrypt the string
string aeCiphertext = rj.Encrypt(plaintext, password, RJCrypt.Common.KeySize.Aes256);

// Decrypt the string
plaintext = rj.Decrypt(aeCiphertext, password, RJCrypt.Common.KeySize.Aes256);

Encrypt a file using Rijndael AES 256-bit

string password = "eUCX6V54eTr?C8M";            // The password to encrypt the file with
string plaintextFile = @"D:\Photo.png";         // The file to encrypt
string ciphertextFile = @"D:\ProtectedFiles";   // The encrypted file (extension unnecessary)

// Encrypt the file
rj.Encrypt(plaintextFile, ciphertextFile, password, RJCrypt.Common.KeySize.Aes256);

// Decrypt the file
rj.Decrypt(ciphertextFile, plaintextFile, password, RJCrypt.Common.KeySize.Aes256);

Settings

The Settings class is a set of default values that are changed in the library. Changing these settings by default is not required, but is available for developers who want more precise control of the Rijndael256 encryption system.

// The HashIterations setting is used in several places throughout the lib,
// with Rijndael.Encrypt being just one of them. After making this change,
// any future calls to Rijndael.Encrypt will make use of this new value
Settings.HashIterations = 25000;

// To reset all the settings to their default values
Settings.Reset();
