I’ll expand on Eugenio. If the point of this software is security with e-mail, then having an encryption program that would be easy to open if someone gets the e-mail, then the program is useless. Unless there is something that an average reader doesn’t know about intercepting e-mails that would make it impossible to intercept the file in it’s encrypted and extractable
form, then maybe the software is usable. As it appears at this point, it isn’t worth anything at all
