+.SH DESCRIPTION
+.IX Header "DESCRIPTION"
+\&\fBEVP_SKEYMGMT\fR is a method object that represents symmetric key management
+implementations for different cryptographic algorithms. This method object
+provides functionality to allow providers to import key material from the
+outside, as well as export key material to the outside.
+.PP
+Most of the functionality can only be used internally and has no public
+interface, this opaque object is simply passed into other functions when
+needed.
+.PP
+\&\fBEVP_SKEYMGMT_fetch()\fR looks for an algorithm within a provider that
+has been loaded into the \fBOSSL_LIB_CTX\fR given by \fIctx\fR, having the
+name given by \fIalgorithm\fR and the properties given by \fIproperties\fR.
+.PP
+\&\fBEVP_SKEYMGMT_up_ref()\fR increments the reference count for the given
+\&\fBEVP_SKEYMGMT\fR \fIskeymgmt\fR.
+.PP
+\&\fBEVP_SKEYMGMT_free()\fR decrements the reference count for the given
+\&\fBEVP_SKEYMGMT\fR \fIskeymgmt\fR, and when the count reaches zero, frees it.
+If the argument is NULL, nothing is done.
+.PP
+\&\fBEVP_SKEYMGMT_get0_provider()\fR returns the provider that has this particular
+implementation.
+.PP
+\&\fBEVP_SKEYMGMT_is_a()\fR checks if \fIskeymgmt\fR is an implementation of an
+algorithm that\*(Aqs identified by \fIname\fR.
+.PP
+\&\fBEVP_SKEYMGMT_get0_name()\fR returns the algorithm name from the provided
+implementation for the given \fIskeymgmt\fR. Note that the \fIskeymgmt\fR may have
+multiple synonyms associated with it. In this case the first name from the
+algorithm definition is returned. Ownership of the returned string is
+retained by the \fIskeymgmt\fR object and should not be freed by the caller.
+.PP
+\&\fBEVP_SKEYMGMT_names_do_all()\fR traverses all names for the \fIskeymgmt\fR, and
+calls \fIfn\fR with each name and \fIdata\fR.
+.PP
+\&\fBEVP_SKEYMGMT_get0_description()\fR returns a description of the \fIskeymgmt\fR, meant
+for display and human consumption. The description is at the discretion
+of the \fIskeymgmt\fR implementation.
+.PP
+\&\fBEVP_SKEYMGMT_do_all_provided()\fR traverses all key \fIskeymgmt\fR implementations by
+all activated providers in the library context \fIlibctx\fR, and for each
+of the implementations, calls \fIfn\fR with the implementation method and
+\&\fIdata\fR as arguments.
+.PP
+\&\fBEVP_SKEYMGMT_get0_gen_settable_params()\fR and \fBEVP_SKEYMGMT_get0_imp_settable_params()\fR
+get a constant \fBOSSL_PARAM\fR\|(3) array that describes the settable parameters
+that can be used with \fBEVP_SKEY_generate()\fR and \fBEVP_SKEY_import()\fR correspondingly.
+.SH NOTES
+.IX Header "NOTES"
+\&\fBEVP_SKEYMGMT_fetch()\fR may be called implicitly by other fetching
+functions, using the same library context and properties.
+Any other API that uses symmetric keys will typically do this.
+.SH "RETURN VALUES"
+.IX Header "RETURN VALUES"
+\&\fBEVP_SKEYMGMT_fetch()\fR returns a pointer to the key management
+implementation represented by an EVP_SKEYMGMT object, or NULL on
+error.
+.PP
+\&\fBEVP_SKEYMGMT_up_ref()\fR returns 1 on success, or 0 on error.
+.PP
+\&\fBEVP_SKEYMGMT_names_do_all()\fR returns 1 if the callback was called for all
+names. A return value of 0 means that the callback was not called for any names.
+.PP
+\&\fBEVP_SKEYMGMT_free()\fR doesn\*(Aqt return any value.
+.PP
+\&\fBEVP_SKEYMGMT_get0_provider()\fR returns a pointer to a provider object, or NULL
+on error.
+.PP
+\&\fBEVP_SKEYMGMT_is_a()\fR returns 1 if \fIskeymgmt\fR was identifiable, otherwise 0.
+.PP
+\&\fBEVP_SKEYMGMT_get0_name()\fR returns the algorithm name, or NULL on error.
+.PP
+\&\fBEVP_SKEYMGMT_get0_description()\fR returns a pointer to a description, or NULL if
+there isn\*(Aqt one.
