As the key pairs will be stored in the same place, we are looking for a way to ensure that one user is able to use only its own key pair, and not the key pair of another user.<o:p></o:p></span></p><p class=MsoNormal><span lang=EN-US><o:p> </o:p></span></p><p class=MsoNormal><span lang=EN-US> In this way, I’m thinking on a passphrase to protect the private key, so when the user needs to use its key pair for signing or encrypting, he must provide the passphrase. As he knows its passphrase and not the passphrase of the other key pairs, he is able to use only its own key pair.<o:p></o:p></span></p><p class=MsoNormal><span lang=EN-US><o:p> </o:p></span></p><p class=MsoNormal><span lang=EN-US><o:p> </o:p></span></p><p class=MsoNormal><span lang=EN-US> Until now, the theory.
