Encryption Program is an easy-to-use and small encryption application.
It can be used to encrypt and decrypt any files. It can be distributed and used
freely.
Encryption Program uses bitwise exclusive OR encryption.
Thus, running a file through it once with a given password changes the contents
with a filter specific to the password, and running the new file through with the same password creates a file with the same content as the original.
The operation for encrypting and decrypting is the same; the encryption
process is functional, producing an unique answer each time.
You can encrypt a file by adding it to the list box on the left side of the Encryption Program window. Press the "Add a file..." button and select the file you want or drag a file or files from another window and drop them in the Encryption Program window.
You will see the file name(s) appear in the list box. If you decide you dont want to encrypt a file, you can remove it from the list by selecting it and pressing the "Delete File" button.
When youve put all the files you want to convert in the file list, type your password into the password and confirmation boxes.
Your password must be six characters in length or greater, and must be identical in both boxes.
When these conditions are met, and there are files in the file list, the "Run" button will become available.
Press it, and the files in the list will be encrypted/decrypted and will disappear from the list.
If the encryption fails for some reason, a message box telling you this will appear and the name will remain on the list.
By default, Encryption Program checks to see if the files you have given it have the extension "cpt". If they do, the newly converted file will have the same name with the "cpt" removed. If they dont, the "cpt"extension will be added.
Thus, when you first encrypt a file it will be designated by the "cpt" extension, and when you decrypt a "cpt" file the original filename will be restored.
