Extract expiration date from a PFX file digital certificate Can't Post
Usng Perl, I need to be able to extract the expiration date from a PFX file digital certificate.

I have limited options when it comes to installing new modules on our AIX server, so if ghere is a way using Crypt::SSLeay, then I would be very appreciative if someone could help me.

Thanks

mattman,

A quick Google indicates that the trick is decoding the certificate, not parsing the result. Here's one writeup at: http://www.planetlarg.net/closed-source/websec-certificate-decode.htm. Once you've got the certificate in plain text, it will be trivial to extract the expiration date.

update: For more on PFX and related standards, try the X.509 wiki at: http://en.wikipedia.org/wiki/X.509

Good luck,

Larry
