DESCRIPTION
These functions are primarily useful for applications to retrieve
supported objects from OSSL_STORE_INFO objects and for scheme specific
loaders to create OSSL_STORE_INFO holders.
Types
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>() where <TYPE> can be NAME, PARAMS,
PKEY, CERT, or CRL. The life time of this extracted object is as long
as the life time of the 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
OSSL_STORE_INFO has been freed. The object returned by
STORE_INFO_get1_<TYPE>() must be freed separately by the caller. See
"SUPPORTED OBJECTS" for more information on the types that are
supported.
Functions
OSSL_STORE_INFO_get_type() takes a 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_PUBKEY(),
OSSL_STORE_INFO_get0_PKEY(), OSSL_STORE_INFO_get0_CERT(),
OSSL_STORE_INFO_get0_CRL() all take a OSSL_STORE_INFO and return the
object it holds if the OSSL_STORE_INFO type (as returned by
OSSL_STORE_INFO_get_type()) matches the function, otherwise NULL.
OSSL_STORE_INFO_get1_NAME(), OSSL_STORE_INFO_get1_NAME_description(),
OSSL_STORE_INFO_get1_PARAMS(), OSSL_STORE_INFO_get1_PUBKEY(),
OSSL_STORE_INFO_get1_PKEY(), OSSL_STORE_INFO_get1_CERT() and
OSSL_STORE_INFO_get1_CRL() all take a OSSL_STORE_INFO and return a
duplicate the object it holds if the OSSL_STORE_INFO type (as returned
by OSSL_STORE_INFO_get_type()) matches the function, otherwise NULL.
OSSL_STORE_INFO_free() frees a OSSL_STORE_INFO and its contained type.
OSSL_STORE_INFO_new_NAME() , OSSL_STORE_INFO_new_PARAMS(), ,
OSSL_STORE_INFO_new_PUBKEY(), OSSL_STORE_INFO_new_PKEY(),
OSSL_STORE_INFO_new_CERT() and OSSL_STORE_INFO_new_CRL() create a
OSSL_STORE_INFO object to hold the given input object. On success the
input object is consumed.
Additionally, for 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.
OSSL_STORE_INFO_new() creates a OSSL_STORE_INFO with an arbitrary type
number and data structure. It's the responsibility of the caller to
define type numbers other than the ones defined by <openssl/store.h>,
and to handle freeing the associated data structure on their own.
Using type numbers that are defined by <openssl/store.h> may cause
undefined behaviours, including crashes.
OSSL_STORE_INFO_get0_data() returns the data pointer that was passed to
OSSL_STORE_INFO_new() if type matches the type number in info.
OSSL_STORE_INFO_new() and OSSL_STORE_INFO_get0_data() may be useful for
applications that define their own STORE data, but must be used with
care.
SUPPORTED OBJECTS
Currently supported object types are:
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
"file:/foo/bar/" could include a file named "cookie.pem", and in
that case, the returned OSSL_STORE_INFO_NAME object would have the
URI "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 "file:" URIs that are used without the explicit scheme, the
returned name will be the path of each object, so if "/foo/bar" was
given and that path has the file "cookie.pem", the name
"/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.
OSSL_STORE_INFO_PARAMS
Key parameters.
OSSL_STORE_INFO_PKEY
A keypair or just a private key (possibly with key parameters).
OSSL_STORE_INFO_PUBKEY
A public key (possibly with key parameters).
OSSL_STORE_INFO_CERT
An X.509 certificate.
OSSL_STORE_INFO_CRL
A X.509 certificate revocation list.
RETURN VALUES
OSSL_STORE_INFO_get_type() returns the STORE type number of the given
OSSL_STORE_INFO. There is no error value.
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 return a
pointer to the OpenSSL object on success, NULL otherwise.
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 return a
pointer to a duplicate of the OpenSSL object on success, NULL
otherwise.
OSSL_STORE_INFO_type_string() returns a string on success, or NULL on
failure.
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() return a OSSL_STORE_INFO pointer on success,
or NULL on failure.
OSSL_STORE_INFO_set0_NAME_description() returns 1 on success, or 0 on
failure.
