EasyEncryption

NuGet version (SoftCircuits.EasyEncryption)

Install-Package SoftCircuits.EasyEncryption

The .NET Framework provides a number of encryption routines. However, these routines generally require a bit of work to set up correctly. Use EasyEncryption to make these encryption routines more easily accessible.

Encrypting a String

The Encrypt() method can be used to encrypt a string. Use DecryptString() to decrypt the string back to the original.

Encryption encrypt = new Encryption("Password123", EncryptionAlgorithm.TripleDes);

string original = "This is my message";
string cipher = encrypt.Encrypt(original);
string result = encrypt.DecryptString(cipher);

Debug.Assert(result == message);

Encrypting other Types

The Encrypt() method is overloaded to encrypt many different data types. When decrypting, you must use the decryption method specific to the data type you are decrypting. This example encrypts an int and double value.

Encryption encrypt = new Encryption("Password123", EncryptionAlgorithm.TripleDes);

int originalInt = 55;
double originalDouble = 123.45;
string cipherInt = encrypt.Encrypt(originalInt);
string cipherDouble = encrypt.Encrypt(originalDouble);
int resultInt = encrypt.DecryptInt32(cipherInt);
double resultDouble = encrypt.DecryptDouble(cipherDouble);

Debug.Assert(resultInt == originalInt);
Debug.Assert(resultDouble == originalDouble);

Streams

EasyEncryption also provides the streaming classes EncryptionWriter and EncryptionReader. These classes work well when encrypting to (or decrypting from) files.

The following example uses the CreateStreamWriter() to encrypt a number of integer values to a file.

Encryption encrypt = new Encryption("Password123", EncryptionAlgorithm.TripleDes);
int[] intValues = { 123, 88, 902, 27, 16, 4, 478, 54 };

using (EncryptionWriter writer = encrypt.CreateStreamWriter(path))
{
    for (int i = 0; i < intValues.Length; i++)
        writer.Write(intValues[i]);
}

Use the CreateStreamReader() method to decrypt those integer values from the file.

Encryption encrypt = new Encryption("Password123", EncryptionAlgorithm.TripleDes);
int[] intValues = new int[8];

using (EncryptionReader reader = encrypt.CreateStreamReader(path))
{
    for (int i = 0; i < intValues.Length; i++)
        intValues[i] = reader.ReadInt32();
}

Also, the CreateStreamWriter() and CreateStreamReader() methods are overloaded to accept a stream argument, allowing you to use custom streams. For example, you could use a MemoryStream to encrypt data to memory. This is demonstrated in the following example. It also uses the static method EncodeBytesToString() method to convert the results to a string. (Note that there is also a corresponding static DecodeBytesFromString() method.)

Encryption encrypt = new Encryption("Password123", EncryptionAlgorithm.TripleDes);

using (MemoryStream stream = new MemoryStream())
using (EncryptionWriter writer = encrypt.CreateStreamWriter(stream))
{
    writer.Write("ABC");
    writer.Write(123);
    writer.Write(123.45);
    string s = Encryption.EncodeBytesToString(stream.ToArray());
}

Note that the streaming classes are actually the most efficient way to encrypt and decrypt data. In fact the Encrypt() and decryption methods create an instance of EncryptionWriter internally (using a MemoryStream), even when only encrypting or decrypting a single byte.

In addition, it should be pointed out that the encrypted results produced by these routines include embedded meta data, making the encrypted data slightly larger than it would otherwise be. However, when encrypting to a stream, this data would only be stored once regardless of the number of values added to the stream. The takeaway is that you can use the Encrypt() method for a simple encryption, but should use the streaming classes for anything more complex.

SoftCircuits.WinSettings

.NET class library that makes it easy to save your application settings in Windows. Just create your settings class and have it derive from RegistrySettings (saves settings to the system registry), XmlSettings (saves settings to an XML file) or IniSettings (saves settings to an INI file). Just call the Save() method to save the class properties. Use the Load() method to load them. Use the [EncryptedSetting] attribute to specify a property should be stored. Use the [ExcludeSetting] to specify that a property does not represent an application setting and should not be saved.
