@@ -35,8 +45,22 @@ structure is freed.
 EVP_SIGNATURE_up_ref() increments the reference count for an B<EVP_SIGNATURE>
 structure.
 
+EVP_SIGNATURE_is_a() returns 1 if I<signature> is an implementation of an
+algorithm that's identifiable with I<name>, otherwise 0.
+
 EVP_SIGNATURE_provider() returns the provider that I<signature> was fetched from.
 
+EVP_SIGNATURE_do_all_provided() traverses all SIGNATURE implemented by all
+activated roviders in the given library context I<libctx>, and for each of the
+implementations, calls the given function I<fn> with the implementation method
+and the given I<arg> as argument.
+
+EVP_SIGNATURE_number() returns the internal dynamic number assigned to
+I<signature>.
+
+EVP_SIGNATURE_names_do_all() traverses all names for I<signature>, and calls
+I<fn> with each name and I<data>.
+
 =head1 RETURN VALUES
 
 EVP_SIGNATURE_fetch() returns a pointer to an B<EVP_SIGNATURE> for success
