21Same as --tls13-ciphers but used in HTTPS proxy context.
22
23Specify which cipher suites to use in the connection to your HTTPS proxy when
24it negotiates TLS 1.3. The list of ciphers suites must specify valid ciphers.

29This option is used when curl is built to use OpenSSL 1.1.1 or later,
30Schannel, wolfSSL, or mbedTLS 3.6.0 or later.
31
32Before curl 8.10.0 with mbedTLS or wolfSSL, TLS 1.3 cipher suites were set
33by using the --proxy-ciphers option.
