-The EVP_PKEY_verify_recover_init_ex() function initializes a public key
-algorithm context for performing signature signed data recovery using the
-signature algorithm B<signature>.
-The signature algorithm B<signature> should be fetched using a call to
-L<EVP_SIGNATURE_fetch(3)>.
-The EVP_PKEY object associated with B<ctx> must be compatible with that
-algorithm.
-B<signature> may be NULL in which case the EVP_SIGNATURE algorithm is fetched
-implicitly based on the type of EVP_PKEY associated with B<ctx>.
-See L<provider(7)/Implicit fetch> for more information about implict fetches.
-
-The EVP_PKEY_verify_recover_init() function is the same as
-EVP_PKEY_verify_recover_init_ex() except that the EVP_SIGNATURE algorithm is
-always implicitly fetched.
+EVP_PKEY_verify_recover_init() initializes a public key algorithm context
+I<ctx> for signing using the algorithm given when the context was created
+using L<EVP_PKEY_CTX_new(3)> or variants thereof. The algorithm is used to
+fetch a B<EVP_SIGNATURE> method implicitly, see L<provider(7)/Implicit fetch>
+for more information about implict fetches.
