libssl_compat.h revision 316069 
1/*
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.
