该代码有些问题，出现句柄泄露和内存泄露！令外缺少结构和函数声明的头文件！在ＶＣ６．０下需要自定义这些函数和结构!

令外
if ( NULL != hCatInfo )
{
CryptCATAdminReleaseContext( hCatInfo, 0 );
}
CryptCATAdminReleaseCatalogContext( hCatAdmin, hCatInfo, 0 );
这句写的有问题
应该在这样的

CryptCATAdminReleaseCatalogContext( hCatAdmin, hCatInfo, 0 );
if ( NULL != hCatAdmin)
{
CryptCATAdminReleaseContext( hCatAdmin, 0 );
}
