dear all
i have made a client server code the client sends a X509 request and the
server reply the X509 certificate but i have 2 questions
1- did i fill all the attributes of the X509 certificate in this code or not
2- when i compile this code using eclipse i got allot of errors but all are
the same
/home/amirale32/workspace/certificate/Debug/../src/client.cc:34: undefined
reference to `RSA_generate_key'
./src/client.o: In function `Client::SetPublicKey()':
i have attached the code
thx allot for help

Warmest regards and best wishes for a good health,*urs sincerely *
