Sometimes univention support requests sentitive information during incident processing.
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 "[http://download.univention.de/download/univention-support.asc](http://download.univention.de/download/univention-support.asc)" -O - | gpg --import
# To encrypt a file:
gpg --encrypt --trust-model always -a -r "email@example.com"
# To encrypt a string string:
echo "Secret string" | gpg --encrypt --trust-model always -a -r "firstname.lastname@example.org"
