Struct curl::easy::SslOpt

pub struct SslOpt { /* private fields */ }

Structure which stores possible ssl options to pass to ssl_options.

Implementations

impl SslOpt

pub fn new() -> SslOpt

Creates a new set of SSL options.

pub fn auto_client_cert(&mut self, on: bool) -> &mut SslOpt

Tell libcurl to automatically locate and use a client certificate for authentication, when requested by the server.

This option is only supported for Schannel (the native Windows SSL library). Prior to 7.77.0 this was the default behavior in libcurl with Schannel.

Since the server can request any certificate that supports client authentication in the OS certificate store it could be a privacy violation and unexpected. (Added in 7.77.0)

pub fn native_ca(&mut self, on: bool) -> &mut SslOpt

Tell libcurl to use the operating system’s native CA store for certificate verification.

Works only on Windows when built to use OpenSSL.

This option is experimental and behavior is subject to change. (Added in 7.71.0)

pub fn revoke_best_effort(&mut self, on: bool) -> &mut SslOpt

Tells libcurl to ignore certificate revocation checks in case of missing or offline distribution points for those SSL backends where such behavior is present.

This option is only supported for Schannel (the native Windows SSL library).

If combined with CURLSSLOPT_NO_REVOKE, the latter takes precedence. (Added in 7.70.0)

pub fn no_partial_chain(&mut self, on: bool) -> &mut SslOpt

Tells libcurl to not accept “partial” certificate chains, which it otherwise does by default.

This option is only supported for OpenSSL and will fail the certificate verification if the chain ends with an intermediate certificate and not with a root cert. (Added in 7.68.0)

pub fn no_revoke(&mut self, on: bool) -> &mut SslOpt

Tells libcurl to disable certificate revocation checks for those SSL backends where such behavior is present.

Currently this option is only supported for WinSSL (the native Windows SSL library), with an exception in the case of Windows’ Untrusted Publishers blacklist which it seems can’t be bypassed. This option may have broader support to accommodate other SSL backends in the future. https://curl.haxx.se/docs/ssl-compared.html

pub fn allow_beast(&mut self, on: bool) -> &mut SslOpt

Tells libcurl to not attempt to use any workarounds for a security flaw in the SSL3 and TLS1.0 protocols.

If this option isn’t used or this bit is set to 0, the SSL layer libcurl uses may use a work-around for this flaw although it might cause interoperability problems with some (older) SSL implementations.

WARNING: avoiding this work-around lessens the security, and by setting this option to 1 you ask for exactly that. This option is only supported for DarwinSSL, NSS and OpenSSL.
