+.Ft X509_INFO *
+.Fn X509_INFO_new void
+.Ft void
+.Fn X509_INFO_free "X509_INFO *info"
+.Sh DESCRIPTION
+.Vt X509_INFO
+is a reference-counted wrapper object storing a pointer to an X.509
+certificate together with pointers to the associated private key
+and to an associated certificate revocation list.
+It is for example used internally by
+.Xr X509_load_cert_crl_file 3 .
+.Pp
+.Fn X509_INFO_new
+allocates and initializes an empty
+.Vt X509_INFO
+object and sets its reference count to 1.
+.Pp
+.Fn X509_INFO_free
+decrements the reference count of
+.Fa info
+by 1.
+If the reference count reaches 0, it frees all referenced objects
+as well as the storage needed for
+.Fa info
+itself.
+If
+.Fa info
+is a
+.Dv NULL
+pointer, no action occurs.
+.Sh RETURN VALUES
+.Fn X509_INFO_new
+returns the newly allocated
+.Vt X509_INFO
+object or
+.Dv NULL
+if an error occurs.
