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