Primary LanguageC

Babassl Rust bindings

openssl-sys/tongsuo 锁定在 https://github.com/Tongsuo-Project/Tongsuo/commit/d36d0669a206e1c07e1793496124ab38435f9bac

兼容openssl 1.1.1

Pre installation

git submodule update --init --remote --recursive
apt install clang pkg-config -y

Building

cargo build

使用

openssl = { version = "0.10.42", path = "../deps/rust-openssl/openssl/", features = ["tokio", "tongsuo"]}

features

  • tokio: 支持async
  • tongsuo：开启rust-openssl bindgen feature。支持gm

注意 在Babassl逻辑中，如果SSL_CTX开启ntls，请求到来后会从socket里MSG_PEEK，判断是NTLS则走到ntls的逻辑分支。

这要求stream必须具有as_raw_fd的能力。rust-openssl使用非socket形式的bio，本身不支持MSG_PEEK。如果请求混合存在标准tls，ntls请求，就会导致请求hangup。 本库提供了额外两个接口

SSL#set_ssl_method

ssl.set_ssl_method(SslMethod::ntls());

SSL#disable_ntls

ssl.disable_ntls()

所以上面问题的解决办法是 初始化SSL_CTX时开启ntls

请求到来后，手写TLS Sniffer，从client hello获取SNI，判断是否开启ntls

开启则ssl.ssl.set_ssl_method(SslMethod::ntls());，否则 ssl.disable_ntls。
