示例1：

       #include <openssl/conf.h>

       int    main()

       {

              CONF     *conf;

              longeline,result;

              int           ret;

              char*p;

              BIO*bp;

      

              conf=NCONF_new(NULL);

       #if 0

              bp=BIO_new_file("openssl.cnf","r");

              NCONF_load_bio(conf,bp,&eline);

       #else

              ret=NCONF_load(conf,"openssl.cnf",&eline);

              if(ret!=1)

              {

                     printf("err!\n");

                     return -1;

              }

       #endif

              p=NCONF_get_string(conf,NULL,"certs");

              if(p==NULL)

                     printf("no global certs info\n");

              p=NCONF_get_string(conf,"CA_default","certs");

              printf("%s\n",p);

              p=NCONF_get_string(conf,"CA_default","default_days");

              printf("%s\n",p);

              ret=NCONF_get_number_e(conf,"CA_default","default_days",&result);

              printf("%d\n",result);

              ret=NCONF_get_number(conf,"CA_default","default_days",&result);

              printf("%d\n",result);

              NCONF_free(conf);

              return 0;

       }

       本示例用来读取配置文件信息，这些信息可以是字符串也可以是数字。

       NCONF_get_section的用法：

       #include <openssl/conf.h>

       int    main()

       {

              CONF                                 *conf;

              BIO                                    *bp;

              STACK_OF(CONF_VALUE)*v;

              CONF_VALUE                            *one;

              int                                       i,num;

              long                             eline;

             

              conf=NCONF_new(NULL);

              bp=BIO_new_file("openssl.cnf","r");

              if(bp==NULL)

              {

                     printf("err!\n");

                     return -1;

              }

              NCONF_load_bio(conf,bp,&eline);

              v=NCONF_get_section(conf,"CA_default");

              num=sk_CONF_VALUE_num(v);

              printf("section CA_default :\n");

              for(i=0;i<num;i++)

              {

                     one=sk_CONF_VALUE_value(v,i);

                     printf("%s = %s\n",one->name,one->value);

              }

              BIO_free(bp);

              printf("\n");

              return 0;

       }
