CryptoService

CryptoService provides one-way hash and two-way encryption and decryption services.

Package Status

• Aliencube.CryptoService

Getting Started – Console Application

In order to run CryptoService console app, a configuration file – Aliencube.CryptoService.ConsoleApp.exe.config – must be setup beforehand.

Usage

AlienCryptoService.exe (/e|/d) /m:"TEXT" [/f:FILENAME] [/o:FILENAME]

Parameters

/e             Encrypt the text or text file.
/d             Decrypt the text or text file.
/t:"[TEXT]"    Text to encrypt or decrypt. It must be enclosed by double quotes.
/f:[FILENAME]  Filename containing text to encrypt or decrypt.
/o:[FILENAME]  Filename to store text encrypted or decrypted.

NOTE: /e and /d cannot be used at the same time.

Getting Started – CryptoService Library

In order to use CryptoService in your applications, simply copy Aliencube.CryptoService.dll to the application's /bin directory or reference Aliencube.CryptoService.dll to your application project.

Alternatively, you can download the library from NuGet. Its package URL is

Hash Service

.NET framework provides five different hash algorithms, MD5, SHA1, SHA256, SHA384 and SHA512. CryptoService supports all those hash algorithms.

var provider = HashProvider.SHA256           // Sets the hash algorithm to SHA256
var hashService = new HashService(provider); // Creates a new HashService instance

var input = "Hello World";                   // Sets the input text to "Hello World"
var output = hashService.Hash(input);        // Gets the hashed value to output

Console.WriteLine("Input: {0}", input);
Console.WriteLine("Output: {0}", output);

// Input: Hello World
// Output: pZGm1Av0IEBKARczz7exkNYsZb8LzaMrV7J32a2fFG4=

Please note that CryptoService does not put salt for hashing. So it is your own responsibility to add any salt before hashing.

Symmetric Service

.NET framework provides five different symmetric algorithms, Aes, DES, RC2, Rijndael and TripleDES. CryptoService supports all those symmetric algorithms.

var provider = SymmetricProvider.Aes                   // Sets the symmetric algorithm to Aes
var symmetricService = new SymmetricService(provider); // Creates a new SymmetricService instance
symmetricService.Key = "KEY_VALUE";                    // Sets the key value.
symmetricService.Vector = "VECTOR_VALUE";              // Sets the vector value.

var input = "Hello World";                             // Sets the input text to "Hello World"
var encrypted = symmetricService.Encrypt(input);       // Gets the encrypted value to encrypted
var decrypted = symmetricService.Decrypt(encrypted);   // Gets the decrypted value to decrypted

Console.WriteLine("Input: {0}", input);
Console.WriteLine("Encrypted: {0}", encrypted);
Console.WriteLine("Decrypted: {0}", decrypted);

// Input: Hello World
// Encrypted: bdwO/5C8a+pliIoIXtuzfA==
// Decrypted: Hello World

Depending on the symmetric algorithm chosen, the length of key and vector are different.

• Aes: 32/16
• DES: 8/8
• RC2: 16/8
• Rijndael: 32/16
• TripleDES: 24/8

Please note that CryptoService does not put salt for encryption. So it is your own responsibility to add any salt before encryption.
