-The EVP_PKEY_verify_init() function initializes a public key algorithm
-context using key B<pkey> for a signature verification operation.
+EVP_PKEY_verify_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.
