• PEM (Base-64) encoded PKCS#7: This Privacy Enhanced Mail (PEM) format uses lowercase
letters, uppercase letters and numerals to convert a binary PKCS#7 certificate into a printable
form.
• Binary PKCS#12: This is a format for transferring public key and private key certificates.The
private key in a PKCS #12 file is within a password-encrypted envelope. The file’s password is not
connected to your certificate’s public or private passwords. Exporting a PKCS #12 file creates this
and you must provide it to decrypt the contents when you import the file into the ZyWALL.
Note: Be careful not to convert a binary file to text during the transfer process. It is easy
for this to occur since many programs use text files by default.

overwrite existing log messages, starting with the oldest existing log message first.
The commands in my configuration file or shell script are not working properly.
• In a configuration file or shell script, use “#” or “!” as the first character of a command line to
have the ZyWALL treat the line as a comment.
