I'm looking for a way to find the expiration of a certificate file (either .pfx or .cer) without installing it.

I have access to read the file but can not install it.

Uh... double-click the *.cer file. Feast your eyes on the part that says "Valid from x/x/x to x/x/x"

This does not require installing the cert.

What am I missing here?

Welp, sometimes I over think the solution. Thanks! Needless to say, this is exactly what I am looking. – Josh R Nov 15 '13 at 1:20
