Hi All,
I am using the following code to load a DER encoded certificate. In case of
PEM the certificate gets loaded fine but the d2i_X509_fp function always
return me NULL
FILE * fPointer;
X509 *x509Cert = NULL;
fPointer = fopen(szPath,"rb");
if(fPointer == NULL)
{
cout<<"No certifcate found at"<<szPath<<endl;
return 0;
}
//If path is valid then we check if there is
//a certificate on the path that can be loaded
x509Cert = PEM_read_X509(fPointer, NULL, NULL, NULL);
//PEM_read_X509(fPointer, &x509Cert, NULL, NULL);
if(!x509Cert)
{
//cout<<"certificate was not loaded by OpenSSL error method
has to be captured later \n\n one more thing it only supports PEM
format"<<szPath<<endl;
cout<<"not PEM format"<<szPath<<endl;
//////////might be the certificate sent is in DER fortmat so
try converting it to PEM
//d2i_X509();
if(!x509Cert)
{
d2i_X509_fp(fPointer,NULL);
if(!x509Cert)
{
cout<<"The input is not a valid certificate
file"<<endl;
fclose(fPointer);
return 0;
}
}
}
any comments on what I am doing wrong ?
regards
Muhammad Aftab Alam
