EVP_PKEY_sign() does not hash the data to be signed, and therefore is
normally used to sign digests. For signing arbitrary messages, see the

L<EVP_SignInit(3)|EVP_SignInit(3)> signing interfaces instead.

After the call to EVP_PKEY_sign_init() algorithm specific control

The function EVP_PKEY_sign() can be called more than once on the same
context if several operations are performed using the same parameters.
