 =head1 DESCRIPTION
 
-The EVP_PKEY_sign_init() function initializes a public key algorithm
-context using key B<pkey> for a signing operation.
+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>.
