Translations:Concepts/OpenPGP Getting Started/12/en

It is perfectly OK to use OpenPGP on such insecure systems (i.e. normal computers). You and your communication partners(!) just have to be aware of the security level. The next security level are smartcards. You cannot steal a key from a smartcard (you can abuse it nonetheless if you control the system to which the smardcard is connected). The next level after smartcards are secure systems: Unconnect your harddisk, all USB sticks (and the like) and the network, boot from a secure medium like a Linux live DVD (from a trusted source, of course!). Use high security keys in such a secure environment only (and maybe even limited to safe document formats like plain text or HTML).
