Problem:
Sometimes univention support requests sentitive information during incident processing.
Solution:
GPG might be used to encrypt strings (like passwords for example) or files to send them via mail to the univention support.
This can be done via GPG/PGP plugins for different mail clients or manually via the command line of an UCS system
# Import Univention support public key (this needs to be done only once)
wget -q "https://updates.software-univention.de/download/univention-support.asc" -O - | gpg --import
# To encrypt a file:
gpg --encrypt --trust-model always -a -r "support@univention.de"
# To encrypt a string string:
echo "Secret string" | gpg --encrypt --trust-model always -a -r "support@univention.de"
