Parameters
iPreVerifythe pre-verification status as determined by openssl internally
pStoreCTXthe X509_STORE_CTX containing the certificate
Returns
1 to continue, 0 to abort

This may get called multiple times, for example with a chain certificate which is fairly typical with certificates from godaddy, freessl, etc. Additionally, openssl does not do any host verification, they leave that up to the you. One easy way to deal with this is to wait for SSLHandShakeFinished() and examine the peer certificate
