使用Rust语言实现openGauss数据库驱动 基于SHA256进行权限认证 能够执行增删改查SQL语句 ## 方案介绍 - 思路 ✗ 参考 JDBC 标准，使用 rust 语言实现一个简单的只包含核心部分的版本 ✓ 基于开源的 rust-postgres 驱动开发，实现基于 sha256 的鉴权方式连接 openGuass 数据库 ✗ 使用-rust语言已有的-sha256方式 ✗ 使用-rust语言已有的RFC5802三方包 使用-rust语言已有的RFC5802三方包 ✓ 参考已有的基于 JAVA 语言实现的 openGauss sha256 鉴权代码，使用 rust 语言重新实现 ## 方案介绍 - 认证流程 startup 会首先建立连接，同时会发送认证协议的版本； 服务器会响应具体的认证方式以及该认证方式所需的信息； 客户端根据要求的认证方式通过认证后，就可以向服务器端发送各种数据库命令  ## 方案介绍 - SHA256认证 SHA256 认证是 openGuass 在 postgres 支持的认证方法之上，额外提供的一种更安全的认证方式。其认证流程遵循 RFC5802 标准 ![Image](/uploads/do
