如何使用Openssl加载证书撤销列表

下面给出一种使用Openssl加载证书撤销列表的方法，该方法只能加载Pem格式的证书撤销列表

#include <openssl/bio.h>

#include <openssl/x509.h>

#include <openssl/pem.h>

#include <iostream>

using namespace std;

void main()

{

X509_CRL *m_crl = NULL;

BIO *bio = NULL;

bio=BIO_new_file("crlTestPem.crl", "r");

if (bio == NULL)

{

cout<<"bio null"<<endl;

}

m_crl=PEM_read_bio_X509_CRL(bio,NULL,NULL,NULL);

if (m_crl == NULL)

{

cout<<"null"<<endl;

}

else

{

cout<<"success"<<endl;

}

}
