Pretty Print Certificate

The Pretty Print Certificate utility, PrettyPrintCert, prints the contents of a certificate stored as
ASCII base-64 encoded data to a readable format.

8.1. Syntax

The PrettyPrintCert command has the following syntax:
PrettyPrintCert [-simpleinfo] input_file [output_file]
Option
simpleinfo
input_file
output_file

8.2. Usage

The following example converts the ASCII base-64 encoded certificate in the ascii_cert.in file
and writes the certificate in the pretty-print form to the output file ascii_cert.out.
PrettyPrintCert /usr/home/smith/test/ascii_cert.in /usr/home/smith/test/ascii_cert.out
The base-64 encoded certificate data in the ascii_cert.in looks like the following:
-----BEGIN CERTIFICATE-----

-----END CERTIFICATE-----
The certificate in pretty-print format in the ascii_cert.out file looks like the following:
