The following public functions is added: - OSSL_SERIALIZER_CTX_new_by_EVP_PKEY() - OSSL_SERIALIZER_CTX_set_cipher() - OSSL_SERIALIZER_CTX_set_passphrase() - OSSL_SERIALIZER_CTX_set_passphrase_cb() - OSSL_SERIALIZER_CTX_set_passphrase_ui() OSSL_SERIALIZER_CTX_new_by_EVP_PKEY() selects a suitable serializer for the given EVP_PKEY, and sets up the OSSL_SERIALIZER_CTX to function together with OSSL_SERIALIZER_to_bio() and OSSL_SERIALIZER_to_fp(). OSSL_SERIALIZER_CTX_set_cipher() indicates what cipher should be used to produce an encrypted serialization of the EVP_PKEY. This is passed directly to the provider using OSSL_SERIALIZER_CTX_set_params(). OSSL_SERIALIZER_CTX_set_passphrase() can be used to set a pass phrase to be used for the encryption. This is passed directly to the provider using OSSL_SERIALIZER_CTX_set_params(). OSSL_SERIALIZER_CTX_set_passphrase_cb() and OSSL_SERIALIZER_CTX_set_passphrase_ui() sets up a callback to be used to prompt for a passphrase. This is stored in the context, and is called via an internal intermediary at the time of serialization.

=head1 DESCRIPTION
|
|
|
|
=for comment Future development should also talk about deserialization
|
|
|
|
B<OSSL_SERIALIZER> is a method for serializers, which know how to
|
|
serialize an object of some kind to a serialized form, such as PEM,
|
|
DER, or even human readable text.
|
|
|
|
OSSL_SERIALIZER_fetch() looks for an algorithm within the provider that
|
|
has been loaded into the B<OPENSSL_CTX> given by I<ctx>, having the
|
|
name given by I<name> and the properties given by I<properties>.
|
|
The I<name> determines what type of object the fetched serializer
|
|
method is expected to be able to serialize, and the properties are
|
|
used to determine the expected output type.
|
|
For known properties and the values they may have, please have a look
|
|
in L<provider-serializer(7)/Names and properties>.
|
|
|
|
OSSL_SERIALIZER_up_ref() increments the reference count for the given
|
|
I<serializer>.
|
|
|
|
OSSL_SERIALIZER_free() decrements the reference count for the given
|
|
I<serializer>, and when the count reaches zero, frees it.
|
|
|
|
OSSL_SERIALIZER_provider() returns the provider of the given
|
|
I<serializer>.
|
|
|
|
OSSL_SERIALIZER_provider() returns the property definition associated
|
|
with the given I<serializer>.
|
|
|
|
OSSL_SERIALIZER_is_a() checks if I<serializer> is an implementation of an
|
|
algorithm that's identifiable with I<name>.
|
|
|
|
OSSL_SERIALIZER_number() returns the internal dynamic number assigned to
|
|
the given I<serializer>.
|
|
|
|
OSSL_SERIALIZER_names_do_all() traverses all names for the given
|
|
I<serializer>, and calls I<fn> with each name and I<data>.
|
|
|
|
OSSL_SERIALIZER_do_all_provided() traverses all serializer
|
|
implementations by all activated providers in the library context
|
|
I<libctx>, and for each of the implementations, calls I<fn> with the
|
|
implementation method and I<data> as arguments.
|
|
|
|
=head1 NOTES
|
|
|
|
OSSL_SERIALIZER_fetch() may be called implicitly by other fetching
|
|
functions, using the same library context and properties.
|
|
Any other API that uses keys will typically do this.
|
|
|
|
=head1 RETURN VALUES
|
|
|
|
OSSL_SERIALIZER_fetch() returns a pointer to the key management
|
|
implementation represented by an OSSL_SERIALIZER object, or NULL on
|
|
error.
|
|
|
|
OSSL_SERIALIZER_up_ref() returns 1 on success, or 0 on error.
|
|
|
|
OSSL_SERIALIZER_free() doesn't return any value.
|
|
|
|
OSSL_SERIALIZER_provider() returns a pointer to a provider object, or
|
|
NULL on error.
|
|
|
|
OSSL_SERIALIZER_properties() returns a pointer to a property
|
|
definition string, or NULL on error.
|
|
|
|
OSSL_SERIALIZER_is_a() returns 1 of I<serializer> was identifiable,
|
|
otherwise 0.
|
|
|
|
OSSL_SERIALIZER_number() returns an integer.
