Digital Certificate Parsing Library in C++?

I used Crypto++ for my applicat开发者_运维百科ion. However it lacks a digital certificate parser. I know that openSSL has one, but I have to learn the whole library again.

Is there some parsing library existing for C++? All I want is to read the certificate and extract some fields, including the public key.

I don't know of any really common ASN.1 libraries, but the format as used by certificate files is actually dead easy to parse.
