The main window of Conceal maintains two panels for Encryption and Decryption, respectively.
You can drag and drop the appropriate file on one of the panel in order to initiate the corresponding process.
File can also be added by Double-clicking on the panels.
Conceal would analyze the file type and upon acceptance it prompts you to choose your destination path- where the encrypted file will be saved and to enter your password to encrypt the file.
Here you'll be given some additional options like- wether, after encryption, you want to keep your original file or not.
Then you have a set of options under Options Button, where you can select the particular encryption algorithm you wish to use, depending on personal or organizational needs. If none selected Conceal uses default algorithm to encrypt.
Click Save and Close label and your file is encrypting.. !!
