OpenSSL uses different APIs to specify the cipher list for
TLSv1.2 and below and to specify the ciphersuites for TLSv1.3.
When calling setCipherList, use this value to delimit them:
values before cipherListTLS13Delimiter will be specified via
SSL_CTX_set_cipher_list (for TLSv1.2 and older), and those
after cipherListTLS13Delimiter will be specified via
SSL_CTX_set_ciphersuites (for TLSv1.3).
