While stereotyped repetitions are frowned upon in literature, they serve a useful purpose in manual pages, because it is easier for the user to find certain information if it is always presented in the same way. For that reason, this commit harmonizes the varying formulations in the HISTORY section about which functions, flags, etc. were added in which OpenSSL version. It also attempts to make the pod files more grep friendly by avoiding to insert line breaks between the symbol names and the corresponding version number in which they were introduced (wherever possible). Some punctuation and typographical errors were fixed on the way. Reviewed-by: Tim Hudson <tjh@openssl.org> (Merged from https://github.com/openssl/openssl/pull/7854)

=head1 DESCRIPTION
|
|
|
|
These functions are primarily useful for applications to retrieve
|
|
supported objects from B<OSSL_STORE_INFO> objects and for scheme specific
|
|
loaders to create B<OSSL_STORE_INFO> holders.
|
|
|
|
=head2 Types
|
|
|
|
B<OSSL_STORE_INFO> is an opaque type that's just an intermediary holder for
|
|
the objects that have been retrieved by OSSL_STORE_load() and similar
|
|
functions.
|
|
Supported OpenSSL type object can be extracted using one of
|
|
STORE_INFO_get0_TYPE().
|
|
The life time of this extracted object is as long as the life time of
|
|
the B<OSSL_STORE_INFO> it was extracted from, so care should be taken not
|
|
to free the latter too early.
|
|
As an alternative, STORE_INFO_get1_TYPE() extracts a duplicate (or the
|
|
same object with its reference count increased), which can be used
|
|
after the containing B<OSSL_STORE_INFO> has been freed.
|
|
The object returned by STORE_INFO_get1_TYPE() must be freed separately
|
|
by the caller.
|
|
See L</SUPPORTED OBJECTS> for more information on the types that are
|
|
supported.
|
|
|
|
=head2 Functions
|
|
|
|
OSSL_STORE_INFO_get_type() takes a B<OSSL_STORE_INFO> and returns the STORE
|
|
type number for the object inside.
|
|
STORE_INFO_get_type_string() takes a STORE type number and returns a
|
|
short string describing it.
|
|
|
|
OSSL_STORE_INFO_get0_NAME(), OSSL_STORE_INFO_get0_NAME_description(),
|
|
OSSL_STORE_INFO_get0_PARAMS(), OSSL_STORE_INFO_get0_PKEY(),
|
|
OSSL_STORE_INFO_get0_CERT() and OSSL_STORE_INFO_get0_CRL() all take a
|
|
B<OSSL_STORE_INFO> and return the held object of the appropriate OpenSSL
|
|
type provided that's what's held.
|
|
|
|
OSSL_STORE_INFO_get1_NAME(), OSSL_STORE_INFO_get1_NAME_description(),
|
|
OSSL_STORE_INFO_get1_PARAMS(), OSSL_STORE_INFO_get1_PKEY(),
|
|
OSSL_STORE_INFO_get1_CERT() and OSSL_STORE_INFO_get1_CRL() all take a
|
|
B<OSSL_STORE_INFO> and return a duplicate of the held object of the
|
|
appropriate OpenSSL type provided that's what's held.
|
|
|
|
OSSL_STORE_INFO_free() frees a B<OSSL_STORE_INFO> and its contained type.
|
|
|
|
OSSL_STORE_INFO_new_NAME() , OSSL_STORE_INFO_new_PARAMS(),
|
|
OSSL_STORE_INFO_new_PKEY(), OSSL_STORE_INFO_new_CERT() and
|
|
OSSL_STORE_INFO_new_CRL() create a B<OSSL_STORE_INFO>
|
|
object to hold the given input object.
|
|
Additionally, for B<OSSL_STORE_INFO_NAME>` objects,
|
|
OSSL_STORE_INFO_set0_NAME_description() can be used to add an extra
|
|
description.
|
|
This description is meant to be human readable and should be used for
|
|
information printout.
|
|
|
|
=head1 SUPPORTED OBJECTS
|
|
|
|
Currently supported object types are:
|
|
|
|
=over 4
|
|
|
|
=item OSSL_STORE_INFO_NAME
|
|
|
|
A name is exactly that, a name.
|
|
It's like a name in a directory, but formatted as a complete URI.
|
|
For example, the path in URI C<file:/foo/bar/> could include a file
|
|
named C<cookie.pem>, and in that case, the returned B<OSSL_STORE_INFO_NAME>
|
|
object would have the URI C<file:/foo/bar/cookie.pem>, which can be
|
|
used by the application to get the objects in that file.
|
|
This can be applied to all schemes that can somehow support a listing
|
|
of object URIs.
|
|
|
|
For C<file:> URIs that are used without the explicit scheme, the
|
|
returned name will be the path of each object, so if C</foo/bar> was
|
|
given and that path has the file C<cookie.pem>, the name
|
|
C</foo/bar/cookie.pem> will be returned.
|
|
|
|
The returned URI is considered canonical and must be unique and permanent
|
|
for the storage where the object (or collection of objects) resides.
|
|
Each loader is responsible for ensuring that it only returns canonical
|
|
URIs.
|
|
However, it's possible that certain schemes allow an object (or collection
|
|
thereof) to be reached with alternative URIs; just because one URI is
|
|
canonical doesn't mean that other variants can't be used.
|
|
|
|
At the discretion of the loader that was used to get these names, an
|
|
extra description may be attached as well.
|
|
|
|
=item OSSL_STORE_INFO_PARAMS
|
|
|
|
Key parameters.
|
|
|
|
=item OSSL_STORE_INFO_PKEY
|
|
|
|
A private/public key of some sort.
|
|
|
|
=item OSSL_STORE_INFO_CERT
|
|
|
|
An X.509 certificate.
|
|
|
|
=item OSSL_STORE_INFO_CRL
|
|
|
|
A X.509 certificate revocation list.

=head1 RETURN VALUES
|
|

|
|
|
OSSL_STORE_INFO_get0_NAME(), OSSL_STORE_INFO_get0_NAME_description(),
|
|

|
|
OSSL_STORE_INFO_get0_CERT() and OSSL_STORE_INFO_get0_CRL() all return
|
|

|
OSSL_STORE_INFO_get0_NAME(), OSSL_STORE_INFO_get0_NAME_description(),
|
|

|
|
