Enable TLS 1.3 on FreeBSD System

Build TLSv1.3 System Support

OpenSSL 1.1.1 supports TLSv1.3, so we download the openssl 1.1.1 from the openssl official website and build it:

$ cd openssl-1.1.1
$ ./config --prefix=/xjail
$ make
$ doas make install

Test if it supports TLSv1.3

According to this blog, test if the openssl supports TLSv1.3:

$ /xjail/bin/openssl ciphers -s -v "ECDHE:!COMPLEMENTOFDEFAULT" | awk '/TLSv1.3/'
TLS_AES_256_GCM_SHA384  TLSv1.3 Kx=any      Au=any  Enc=AESGCM(256) Mac=AEAD
TLS_CHACHA20_POLY1305_SHA256 TLSv1.3 Kx=any      Au=any  Enc=CHACHA20/POLY1305(256) Mac=AEAD
TLS_AES_128_GCM_SHA256  TLSv1.3 Kx=any      Au=any  Enc=AESGCM(128) Mac=AEAD

New Update: FreeBSD has imported OpenSSL 1.1.1 into the base system which supports TLS v1.3 now ! =>
Using TLS 1.3 FreeBSD and Upgrade System (maybe you upgrade to freebsd 13.0)
