11 Certificate Management
What are
Certificates?
Certificates can be used in TCP/IP-based networks to encrypt data
and to authenticate communication partners. Certificates are elec-
tronic messages containing a key (public key) and a signature.
Benefits and
Purpose
The use of certificates allows for various security mechanisms. Use
certificates in your print server to
• encrypt print data; see: 9.
• check the identity of the print server in the network; see:
107.
• authenticate the print server if the connection to the Printserver
Homepage is encrypted via SSL/TLS (HTTPS).
• administer the print server via an FTPS connection; see: 17.
• allow for a certificate-based authentication of the remote server
in the case of IPsec; see: 11 7.
• to encrypt ThinPrint data; see: 139.
If you want to use certificates, it is advisable to protect the print
server by a password so that the certificate cannot be deleted by
unauthorized persons, see 88.
Which Certificates
are available?
Both self-signed certificates and CA certificates can be used in the
print server. The following certificates can be distinguished:
• Upon delivery, a self-signed certificate (the so-called default
certificate) is stored in the print server. It is recommended that
you replace the default certificate by a self-signed certificate or
requested certificate as soon as possible.
• Self-signed certificates have a digital signature that has been
created by the print server.
The print server has its own certificate management.
This chapter explains how certificates are used and
when the use of certificates is recommended.
