Ein Session Key ist ein einmal verwendeter, zufällig generierter Schlüssel. Er wird zum Beispiel in der hybriden Verschlüsselung verwendet, um die Nutzdaten symmetrisch zu verschlüsseln. Der Session Key selbst wird zufällig erzeugt, danach werden die Nutzdaten damit verschlüsselt und der Session Key asymmetrisch verschlüsselt. Beides wird dann übertragen.
