At the moment we have OpenSSL v1.1.0 support listed, should we drop it? Fine by me, can you update README.md. So we can drop some more checks:

./src/md5/wrap.c:28:#if OPENSSL_VERSION_NUMBER >= 0x10100000L
./src/tls/openssl/tls.h:17:#if OPENSSL_VERSION_NUMBER >= 0x10100000L && \
./src/tls/openssl/tls.h:24:#if OPENSSL_VERSION_NUMBER >= 0x10100000L
./src/tls/openssl/tls.c:144:#if OPENSSL_VERSION_NUMBER >= 0x10100000L && \
./src/tls/openssl/tls.c:438:#if OPENSSL_VERSION_NUMBER >= 0x10100000L
./src/tls/openssl/tls.c:503:#if OPENSSL_VERSION_NUMBER >= 0x10100000L
./src/tls/openssl/tls.c:570:#if OPENSSL_VERSION_NUMBER >= 0x10100000L
./src/tls/openssl/tls.c:1277:#if OPENSSL_VERSION_NUMBER >= 0x10100000L && \
./src/tls/openssl/tls.c:1480:#if (OPENSSL_VERSION_NUMBER >= 0x10100000L)
./src/tls/openssl/tls.c:1504:#if (OPENSSL_VERSION_NUMBER >= 0x10100000L)
./src/tls/openssl/tls_tcp.c:333:#if OPENSSL_VERSION_NUMBER >= 0x10100000L && \

Sorry I did not mean to remove support for 1.1.0

I think we should support these versions:

• OpenSSL 1.1.0
• OpenSSL 1.1.1
• OpenSSL 3.0.0

Over time we can consider to drop the oldest version, if it is a big maintenance burdon.

Can you please check again the VERSION check:

According to https://www.openssl.org/policies/releasestrat.html "Versions 1.1.0, 1.0.1, 1.0.0 and 0.9.8 are no longer supported", thus support for at least OpenSSL 1.1.1 (for CentOS/RHEL/Rocky 7 and 8) would be appreciated.
