Hi All,
I'm new to openssl and I apologize for my ignorance.
I'd like to process X.509 digital certificates -
1. retrieve fields like public key, serial number, subject, issuer, dates,
signature, extended key usage extension
2. verify the signature

and also like to process PKCS#7 message -
1. retrieve certificates
2. retrieve signer info fields (authenticated attributes (content type,
digest, signing time), issuer, signature.
3. verify signer signature.

It seems like the "x509" , "pkcs7" , and "verify" utilities have all
required capabilities.
Where can I find the code to these utilities so I can call the relevant
functions from my application?

I'd appreciate any help,
thanks,
Yael
