=head1 NOTES
The function X509_up_ref() if useful if a certificate structure is being
used by several different operations each of which will free it up after
use: this avoids the need to duplicate the entire certificate structure.
+The function X509_chain_up_ref() doesn't just up the reference count of
+each certificate it also returns a copy of the stack, using sk_X509_dup(),
+but it serves a similar purpose: the returned chain persists after the
+original has been freed.
