22 The following functions have been deprecated since OpenSSL 3.0, and can
24 be hidden entirely by defining OPENSSL_API_COMPAT with a suitable
25 version value, see openssl_user_macros(7):

31 OSSL_HTTP_adapt_proxy() takes an optional proxy hostname proxy and
32 returns it transformed according to the optional no_proxy parameter,
33 server, use_ssl, and the applicable environment variable, as follows.
34 If proxy is NULL, take any default value from the "http_proxy"
35 environment variable, or from "https_proxy" if use_ssl is nonzero. If
36 this still does not yield a proxy hostname, take any further default
37 value from the "HTTP_PROXY" environment variable, or from "HTTPS_PROXY"
38 if use_ssl is nonzero. If no_proxy is NULL, take any default exclusion
39 value from the "no_proxy" environment variable, or else from
40 "NO_PROXY". Return the determined proxy hostname unless the exclusion
41 contains server. Otherwise return NULL.
42 OSSL_parse_url() parses its input string url as a URL of the form
44 "[scheme://][userinfo@]host[:port][/path][?query][#fragment]" and
45 splits it up into scheme, userinfo, host, port, path, query, and
46 fragment components. The host (or server) component may be a DNS name
47 or an IP address where IPv6 addresses should be enclosed in square
48 brackets "[" and "]". The port component is optional and defaults to
49 0. If given, it must be in decimal form. If the pport_num argument is
50 not NULL the integer value of the port number is assigned to *pport_num
51 on success. The path component is also optional and defaults to "/".
52 Each non-NULL result pointer argument pscheme, puser, phost, pport,
53 ppath, pquery, and pfrag, is assigned the respective url component. On
54 success, they are guaranteed to contain non-NULL string pointers, else
55 NULL. It is the reponsibility of the caller to free them using
56 OPENSSL_free(3). If pquery is NULL, any given query component is
57 handled as part of the path. A string returned via *ppath is
58 guaranteed to begin with a "/" character. For absent scheme, userinfo,
59 port, query, and fragment components an empty string is provided.
60 OSSL_HTTP_parse_url() is a special form of OSSL_parse_url() where the
62 scheme, if given, must be "http" or "https". If pssl is not NULL,
63 *pssl is assigned 1 in case parsing was successful and the scheme is
64 "https", else 0. The port component is optional and defaults to 443 if
65 the scheme is "https", else 80. Note that relative paths must be given
66 with a leading "/", otherwise the first path element is interpreted as
67 the hostname.
68 Calling the deprecated function OCSP_parse_url(url, host, port, path,
70 ssl) is equivalent to OSSL_HTTP_parse_url(url, ssl, NULL, host, port,
71 NULL, path, NULL, NULL).
72
74 OSSL_HTTP_adapt_proxy() returns NULL if no proxy is to be used,
75 otherwise a constant proxy hostname string, which is either the proxy
76 name handed in or an environment variable value.
77 OSSL_parse_url(), OSSL_HTTP_parse_url(), and OCSP_parse_url() return 1
79 on success, 0 on error.

83
85 OSSL_HTTP_adapt_proxy(), OSSL_parse_url() and OSSL_HTTP_parse_url()
86 were added in OpenSSL 3.0. OCSP_parse_url() was deprecated in OpenSSL
87 3.0.
