12.1.2 What You Need to Know About Certificates

Certification Authority
A Certification Authority (CA) issues certificates and guarantees the identity of each
certificate owner. There are commercial certification authorities like CyberTrust or VeriSign
and government certification authorities. You can use the ZyXEL Device to generate
certification requests that contain identifying information and public keys and then send the
certification requests to a certification authority.
Certificate File Formats
The certification authority certificate that you want to import has to be in one of these file
formats:
• Binary X.509: This is an ITU-T recommendation that defines the formats for X.509
certificates.
• PEM (Base-64) encoded X.509: This Privacy Enhanced Mail format uses lowercase
letters, uppercase letters and numerals to convert a binary X.509 certificate into a printable
form.
• Binary PKCS#7: This is a standard that defines the general syntax for data (including
digital signatures) that may be encrypted. The ZyXEL Device currently allows the
importation of a PKS#7 file that contains a single certificate.
• PEM (Base-64) encoded PKCS#7: This Privacy Enhanced Mail (PEM) format uses 64
ASCII characters to convert a binary PKCS#7 certificate into a printable form.
