Hi Douglas,
Is this right way to get the peer certificate in a data buffer ?
STACK_OF(X509) *sk;
int ii = 0, noOfCerts = 0 , res = -1;
X509 *certs[15];
unsigned char *intFmtOfCerts[15];
unsigned int len[15];
sk = SSL_get_peer_cert_chain(connssl->handle);
noOfCerts = sk_X509_num(sk) ;
for(ii = 0 ; ii < noOfCerts ; ii++)
{
certs[ii] = sk_X509_value (sk, ii);
len[ii] = i2d_X509( certs[ii] , NULL);
intFmtOfCerts[ii] = (unsigned char *) malloc( len[ii] );
len[ii] = i2d_X509( certs[ii] ,
&intFmtOfCerts[ii] );
}
Thanks,
Aravind.
