Title: RE: processing of X.509 certificates and PKCS#7 messages

Thx Alex,

My question is - where can I find the function main() of these utilities so I can copy parts of it that do the specific capabilities I'm looking for?

 

thanks for your help,

Yael

What do you mean, where can I find the code? Just build the OpenSSL source, and call the functions, which are declared in pkcs7.h and x509.h.

Should work, although you must realize that parts of the PKCS#7 stuff is not completely finished (especially the signed and enveloped part).

Regards,
Alex
