 =head1 DESCRIPTION
 
-The EVP_PKEY_sign_init_ex() function initializes a public key algorithm
-context for performing signing 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_sign_init() function is the same as EVP_PKEY_sign_init_ex() except
-that the EVP_SIGNATURE algorithm is always implicitly fetched.
+EVP_PKEY_sign_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.
 
 The EVP_PKEY_sign() function performs a public key signing operation
-using B<ctx>. The data to be signed is specified using the B<tbs> and
-B<tbslen> parameters. If B<sig> is B<NULL> then the maximum size of the output
-buffer is written to the B<siglen> parameter. If B<sig> is not B<NULL> then
-before the call the B<siglen> parameter should contain the length of the
-B<sig> buffer, if the call is successful the signature is written to
-B<sig> and the amount of data written to B<siglen>.
