Parameters

encryptionType: The encryption algorithm to use
key: The encryption password
input: The bytes to decrypt

C#

Encryption encryption = new Encryption(); //Trial Mode
//Encryption encryption = new Encryption("place user name here", "place license key here"); //License Mode
 
byte[] input = new byte[255];
 
for (int i = 0; i < 255; i++)
    input[i] = (byte)i;
 
byte[] encryptedBytes = encryption.EncryptBytes(EncryptionProvider.Rijndael, "My password", input);
byte[] decryptedBytes = encryption.DecryptBytes(EncryptionProvider.Rijndael, "My password", encryptedBytes);
 
bool decryptedSucessfully = true;
for (int i = 0; i < input.Length; i++)
{
    if (input[i] != decryptedBytes[i])
    {
        decryptedSucessfully = false;
        break;
    }
}
 
Console.WriteLine("Decrypted successfully: {0}", decryptedSucessfully);

VB.NET

Dim encryption As New Encryption() 'Trial Mode
'Dim encryption As New Encryption("place user name here", "place license key here") 'License Mode
 
Dim input(254) As Byte
 
For i As Integer = 0 To 254
    input(i) = CByte(i)
Next i
 
Dim encryptedBytes() As Byte = encryption.EncryptBytes(EncryptionProvider.Rijndael, "My password", input)

Dim decryptedSucessfully As Boolean = True
For i As Integer = 0 To input.Length - 1
    If input(i) <> decryptedBytes(i) Then
        decryptedSucessfully = False
        Exit For
    End If
Next i
 
Console.WriteLine("Decrypted successfully: {0}", decryptedSucessfully)
