   2  * libssl_compat.h -- OpenSSL v1.1 compatibility shims
   3  *
   4  * ---------------------------------------------------------------------
   5  *
   6  * Written by Juergen Perlinger <perlinger@ntp.org> for the NTP project
   7  *
   8  * Based on an idea by Kurt Roeckx <kurt@roeckx.be>
   9  *
  10  * ---------------------------------------------------------------------
  11  * This is a clean room implementation of shim functions that have
  12  * counterparts in the OpenSSL v1.1 API but not in earlier versions.
  13  *
  14  * If the OpenSSL version used for compilation needs the shims (that is,
  15  * does not provide the new functions) the names of these functions are
  16  * redirected to our shims.
