Hello Some crypto drivers cannot process empty data message and so rely on precalculated hash. This patch series add precalculated hash in headers and make the drivers use them. Using those precalculated hash make some additionnal constify patch necessary. Changes since v1 - Moved arrays from headers to c file and made them EXPORT.
