-=head1 NAME
-
-EVP_SIGNATURE_fetch, EVP_SIGNATURE_free, EVP_SIGNATURE_up_ref,
-EVP_SIGNATURE_provider
-- Functions to manage EVP_SIGNATURE algorithm objects
-
-=head1 SYNOPSIS
-
- #include <openssl/evp.h>
-
- EVP_SIGNATURE *EVP_SIGNATURE_fetch(OPENSSL_CTX *ctx, const char *algorithm,
-                                    const char *properties);
- void EVP_SIGNATURE_free(EVP_SIGNATURE *signature);
- int EVP_SIGNATURE_up_ref(EVP_SIGNATURE *signature);
- OSSL_PROVIDER *EVP_SIGNATURE_provider(const EVP_SIGNATURE *signature);
-
-=head1 DESCRIPTION
-
-EVP_SIGNATURE_fetch() fetches the implementation for the given
-B<algorithm> from any provider offering it, within the criteria given
-by the B<properties>.
-The algorithm will be one offering functions for performing signature related
-tasks such as signing and verifying.
-See L<provider(7)/Fetching algorithms> for further information.
-
-The returned value must eventually be freed with EVP_SIGNATURE_free().
-
-EVP_SIGNATURE_free() decrements the reference count for the B<EVP_SIGNATURE>
-structure. Typically this structure will have been obtained from an earlier call
-to EVP_SIGNATURE_fetch(). If the reference count drops to 0 then the
-structure is freed.
-
-EVP_SIGNATURE_up_ref() increments the reference count for an B<EVP_SIGNATURE>
-structure.
-
-EVP_SIGNATURE_provider() returns the provider that I<signature> was fetched from.
-
-=head1 RETURN VALUES
-
-EVP_SIGNATURE_fetch() returns a pointer to an B<EVP_SIGNATURE> for success
-or B<NULL> for failure.
-
-EVP_SIGNATURE_up_ref() returns 1 for success or 0 otherwise.
