The EVP signature routines are a high level interface to digital
signatures.
-EVP_SignInit_ex() sets up signing context B<ctx> to use digest
-B<type> from ENGINE B<impl>. B<ctx> must be created with
+EVP_SignInit_ex() sets up signing context I<ctx> to use digest
+I<type> from B<ENGINE> I<impl>. I<ctx> must be created with
EVP_MD_CTX_new() before calling this function.
-EVP_SignUpdate() hashes B<cnt> bytes of data at B<d> into the
-signature context B<ctx>. This function can be called several times on the
-same B<ctx> to include additional data.

-EVP_SignFinal() signs the data in B<ctx> using the private key B<pkey> and
-places the signature in B<sig>. B<sig> must be at least C<EVP_PKEY_size(pkey)>
-bytes in size. B<s> is an OUT parameter, and not used as an IN parameter.
