How to use

An example with a search of all types of encryption

public void Handler()
{
    /**
    * If you use DES encryption, then you need to pass the encryption key to the constructor.
    * For other types of encryption, a key is not required.
    */
    
    string sentence = "Some input sentence";
    string salt = "my-salt";

    Enum
        .GetNames(enumType: typeof(CipherType))
        .ToList()
        .ForEach(action: type =>
    {
        CipherType cipherType = (CipherType)Enum.Parse(
            enumType: typeof(CipherType),
            value: type
        );

        Cipher cipher = new Cipher(
            type: cipherType,
            key: cipherType.Equals(obj: CipherType.DES) ? salt : default
        );

        string encodedInput = cipher.Encode(input: sentence);
        string decodedInput = string.Empty;

        try
        {
            decodedInput = cipher.Decode(input: encodedInput);
        }
        catch (Exception ex)
        {
            decodedInput = ex.Message;
        }

        Console.WriteLine(string.Join(separator: "\n",
            "– – –",

            $"Encoded: {encodedInput}",
            $"Decoded: {decodedInput}"
        ));
    });

A simple example with two types of encryption

public void Handler()
{
    /**
    * If you use DES encryption, then you need to pass the encryption key to the constructor.
    * For other types of encryption, a key is not required.
    */
    
    string sentence = "Some input sentence";
    string encodedSentence = string.Empty;
    string salt = "my-salt";
    
    encodedSentence = new Cipher(CipherType.AES).Encode(sentence);
    Console.WriteLine($"AES encoded: {encodedSentence}");
    Console.WriteLine($"AES decoded: {new Cipher(CipherType.AES).Decode(encodedSentence)}");
    
    encodedSentence = new Cipher(CipherType.DES, salt).Encode(sentence);
    Console.WriteLine($"DES encoded: {encodedSentence}");
    Console.WriteLine($"DES decoded: {new Cipher(CipherType.DES, salt).Decode(encodedSentence)}");
}
