Can users provide me some steps in how to encrypt part of a binary file?
Here I have this code snippet below:
private void Encrypt_Region_Button_Click(object sender, EventArgs e)
{
try
{
string FileName = @"C:\Users\...\Documents\Binary Image 001.img";
MessageBox.Show("Encrypting " + FileName);
// Encrypt the file.
AddEncryption(FileName);
MessageBox.Show("Done");
}
catch (Exception)
{
MessageBox.Show("Unable to encrypt file.");
}
}
What I want to do now, but I don't know how to perform this is to encrypt part of a binary file.
Can users provide me step by step?
