Re: encryption question

a public/private key is secure as long as the private key is not shared to
any one eg you share the public which is used to encrypt the information
but this encrypted information can only be decrypted by a private key
knowen only to you, in any other case a simple key based encryption would
do just the same.
To answer your question I have invested some thought to this and I have
come to the conclusion that you need two pairs of private/public key


Thanks for reply.

I see from the replies that there were some things left out from my
question.

Your answer wont help me since my case is simply a desktop application,
where I want to secure the "data storage" file, and user must me able to
transfer this file to any computer he desires.
