25: .SH NAME
26: CURLOPT_PROXY_TLS13_CIPHERS \- ciphers suites for proxy TLS 1.3
27: .SH SYNOPSIS
28: #include <curl/curl.h>
29:
30: CURLcode curl_easy_setopt(CURL *handle, CURLOPT_PROXY_TLS13_CIPHERS, char *list);
31: .SH DESCRIPTION
32: Pass a char *, pointing to a zero terminated string holding the list of cipher
33: suites to use for the TLS 1.3 connection to a proxy. The list must be
34: syntactically correct, it consists of one or more cipher suite strings
35: separated by colons.
36:
37: You'll find more details about cipher lists on this URL:
38:
39: https://curl.haxx.se/docs/ssl-ciphers.html
40:
41: This option is currently used only when curl is built to use OpenSSL 1.1.1 or
42: later. If you are using a different SSL backend you can try setting TLS 1.3
43: cipher suites by using the CURLOPT_PROXY_SSL_CIPHER_LIST option.
44:
45: The application does not have to keep the string around after setting this
46: option.
47: .SH DEFAULT
48: NULL, use internal default
49: .SH PROTOCOLS
50: All TLS based protocols: HTTPS, FTPS, IMAPS, POP3S, SMTPS etc.
51: .SH EXAMPLE
52: .nf
53: CURL *curl = curl_easy_init();
54: if(curl) {
55: curl_easy_setopt(curl, CURLOPT_URL, "https://example.com/");
56: curl_easy_setopt(curl, CURLOPT_PROXY_TLS13_CIPHERS,
57: "TLS13-CHACHA20-POLY1305-SHA256");
58: ret = curl_easy_perform(curl);
59: curl_easy_cleanup(curl);
60: }
61: .fi
62: .SH AVAILABILITY
63: Added in 7.61.0.
64: Available when built with OpenSSL >= 1.1.1.
65: .SH RETURN VALUE
66: Returns CURLE_OK if supported, CURLE_NOT_BUILT_IN otherwise.
