on iOS .. unless any new security api points were added in the last release or two, it's not very easy. iOS is pretty weak here and my bugreport asking for more security API points remains open.
You can call SecCertificateCopyData which gives you a DER encoded X.509 cert which you then stick through an ASN1 parser and extract the bits you want. Or if you are feeling lucky you can scan the raw data for the patterns which match the information in the ASN1 data and pick out just the bits you need. I wrote a parser as it's a handy thing to have in the toolbox. There's a SecCertificateCopySubjectSummary function which returns a CFString, I have no idea what's in it, if it has any information you'd find useful, rather doubt it has all the stuff you want, however you could try displaying that to the user.
