Whether for users, groups or servers - it is always important that data and information is exchanged securely between users and web applications or via email.
Digital certificates are a tried and tested way of doing this. They ensure secure authentication of communication partners and thus prevent the impersonation of a false identity. Encryption mechanisms in particular form an essential part of this. The following options are available:
-
Personal certificates (e.g. for signing e-mails)
A personal certificate can be used to sign emails or encrypt documents (e.g. a PDF). The digital signature of an e-mail or document ensures that the document or message actually originates from the sender and not from a completely unrelated third party.

-
Group certificates (e-mails for functional purposes)
A group certificate is used if an e-mail address is used by several people or if it is an e-mail for functional purposes (e.g. dekanat_fak@uni-jena.de).

-
Server certificates (for secure data exchange with web services)
Administrators use a server certificate to secure access to the services tendered by servers. Web services with "https://" in the address line of the browser indicate that data exchanged via this website is transmitted in encrypted form and that no third party can read it.
