Tool for Viewing X.509 Certificates?

Does anyone know of any good tools to view the store name, store location, or values of an X.509 Certificate?

Are x509 certificates public?

509 is an International Telecommunication Union (ITU) standard defining the format of public key certificates. X. 509 certificates are used in many Internet protocols, including TLS/SSL, which is the basis for HTTPS, the secure protocol for browsing the web.

Where are x509 certificates stored?

As previously mentioned, each must be signed by an issuer CA as part of the X. 509 verification process. The CA is named and stored in the root of the certificate. Additional intermediate certificates can be included in the trust chain and must be validated.

Portecle is cross-platform (written in Java), requires no installation and can not only read certificates and keystores but also create, modify, import/export etc.

i'm supposing that you are using Windows. So here it is http://msdn.microsoft.com/en-us/library/aa529278.aspx. It's a good tool, but to do it thru API is not hard and it's a good exercise to learn the API.
