perl and ssl certificate info
Hey;
I have over 100 systems from which I need to get ssl certificate information. The manual method is to hit each web site, view the certificate information, then record the following:
issued to
issued by
valid dates
This just screams for automation - that, or an intern; however, I'll try the automation first.
Does anyone know which modules might contain this information? I'm thinking something in LWP and will be checking shortly - just hoping that someone here knows off the top of their head and save me some research time.
Thanks.

Re: perl and ssl certificate info
Hey;
Turns out the right answer isn't perl - it's the openssl command.
echo | \
openssl s_client -connect ${url}:${port} \
sed -ne '/-BEGIN CERT/,/-END CERT/p' > /tmp/cert.pem
to obtain the cert from the remote site, then:
openssl x509 -noout -in /tmp/cert.pem -issuer -subject -dates
To get the required information from the downloaded cert.
A little perl script to wrap that and format the dates and I'm all done.
