Hallo,<br>
<br>
laut RFC haben wir es bei OpenPGP ja eigentlich mit einem hybriden
System zu tun, ich dachte <br>
GPG ist eine rein asymmetrisches Verfahren. Den symmetrischen Teil
hatte ich nur als Option für die Datenverschlüsselung betrachtet.
Wird das in GnuPG auch so wie im RFC beschrieben, umgesetzt?<br>
<br>
<p>RFC 4880 natürlich: Sektion 2, insbesondere <a
href="https://tools.ietf.org/html/rfc4880#section-2.1"
rel="nofollow" class="external">Sektion 2.1</a>:</p>
<blockquote>
<p>OpenPGP combines symmetric-key encryption and public-key
encryption
to provide confidentiality. When made confidential, first the
object
is encrypted using a symmetric encryption algorithm. Each
symmetric
key is used only once, for a single object. A new "session key"
is
generated as a random number for each object (sometimes referred
to
as a session). Since it is used only once, the session key is
bound
to the message and transmitted with it. To protect the key, it
is
encrypted with the receiver's public key.<br>
</p>
