Please note the following two announcements about the exercise points:

For team solutions: Please check if you have received the same points as your teammates, usually as the team member who uploaded the exercise solution. Due to a bug in the CMS, the CMS does not always automatically assign the points to all team members. If you notice that this bug affects you, please send us a message to correct this issue for your team.
We reduced the points for exam admission to 80 points. Corrections for Ex05 and Ex06 are forthcoming; hence, your admission status should be clearer soon.

Exercise 02: Small correction for Task 1.(d).i

Written on 21.11.22 by Sven Bugiel

Please note a correction for Task 1.(d).i in Ex02: The reference should be to slide 68 of lecture 06. For task 1.(d).i, do not assume that CT is checked by the client, but just the bare certificate validation as depicted on slide 68 "Client Responsibility: Certificate verification."

Mental Health

Being a student during a pandemic is challenging and might be very overwhelming. If you need support during times of struggle, reach out to friends, family, or faculty you trust. The student union at UdS also offers a counseling service that you may contact. You do not have to go through this alone! If for whatever reason (e.g. a personal emergency) you cannot attend the lectures or deliver your work in time, please let us know and we will make appropriate arrangements.
