21Specifies which cipher suites to use in the connection to your HTTPS proxy
22when it negotiates TLS 1.3. The list of ciphers suites must specify valid
23ciphers. Read up on TLS 1.3 cipher suite details on this URL:

27This option is currently used only when curl is built to use OpenSSL 1.1.1 or
28later. If you are using a different SSL backend you can try setting TLS 1.3
29cipher suites by using the --proxy-ciphers option.
