Basic Zip password Encryption (Zip 2.0 encryption method )

Create a Zip in C# using basic Zip password protection (Zip 2.0 encryption method).

// Create a Zip with 
// Basic Zip password Encryption (Zip 2.0 encryption method )
Chilkat.Zip zip = new Chilkat.Zip();

zip.UnlockComponent("Anything for 30-day trial");

// Calling NewZip initializes the zip object in memory.
// it does not create a file on disk.
zip.NewZip("BasicEncrypted.zip");

// Set properties to indicate that the Zip should use
// the Zip 2.0 encryption method

zip.Encryption = 0;
zip.PasswordProtect = true;

// Set the password needed to unzip.
zip.SetPassword("myPassword");

// Append a directory tree.  The AppendFiles does
// not read the file contents or append them to the zip
// object in memory.  It simply appends references
// to the files so that when WriteZip (or WriteZipAndClose,
// or WriteExe, etc.) is called, the files are compressed
// and encrypted.
bool recurse = true;
zip.AppendFiles("c:/temp/a/*", recurse);

// Write "BasicEncrypted.zip"
bool success = zip.WriteZipAndClose();
if (!success)
{
    zip.SaveLastError("zipErrors.txt");
}

MessageBox.Show("Done!");
