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