Self-Extracting Encrypted Archive
To create a self-extracting encrypted archive, click on the "Convert to SFX" button in the Encryption section under Tools, in the main menu. A self-extracting encrypted archive is an encrypted archive that doesn't require TUGZip to decrypt them. They simply decrypt themselves if the correct password is supplied.
 
Encrypted file
  In this field you specify which encrypted file that you want to convert to a self-extracting encrypted file. Note that the source file will not be deleted when converting.
 
Stub type
  A stub contains the executable code that will be added to the encrypted file. It contains decryption algorithms so it can decrypt itself. There are currently two types of stubs available, a DOS version and a Windows version.
