i'm new to file encryption. I tried it earlier, and i'm a bit confused. this is what i did:
I encrypted an excel file, and send it along with my outlook email. The recipient was able to open it just fine on a different computer. i didn't provide him with public key. why is this happening? isn't the recipient NOT supposed to be able to open the attachment because i didn't sent him any public key??
I then access my computer running win7(comp1) from a different computer running xp(comp2) using UNC path(shared folder). I copy the encrypted excel file from comp1 to comp2, and I could opened it just fine in comp2. isn't this supposed NOT to happen?
