15.5 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 64 ASCII characters 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 ZyWALL 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.
