Flutter 3.29.1-使用U盾完成数据的加解密（国密算法SKF接口）

参考 Python3-使用U盾完成数据的加解密（国密算法SKF接口），那么相同的功能如何使用 Flutter FFI 实现呢？

Flutter 3.29.1

ffi 2.1.4

pointycastle 3.6.0

pkcs7 1.0.5

convert 3.1.2

Gtk应用内嵌网页与原生代码交互方法

前置条件

Ubuntu 24.04.2 LTS

内容详情

在使用Gtk开发应用程序的过程中，如果需要内嵌网页，那么使用libwebkit2gtk是个非常自然和正确的选择。

那么这里就可能原生程序代码可能需要跟网页交互的问题。

Gtk程序跟网页的交互，主要有两个方面：

1 Gtk程序需要调用网页js代码 

2 网页需要调用 Gtk 程序的功能代码

1 Gtk程序需要调用网页js代码

2 网页需要调用 Gtk 程序的功能代码

需求1，使用 webkit2gtk 的内置 webkit_web_view_run_javascript 函数即可解决

需求2，使用 webkit2gtk 的内置的 web extendsion 扩展支持功能解决或 window.webkit.messageHandlers..postMessage(value)

不多说看代码吧！

应用内嵌WebKitGTK报错“Unacceptable TLS certificate”

在 ubuntu 24.04 系统开发内嵌 webkit2gtk-4.1 的应用，打开部分 HTTPS 网页报错“Unacceptable TLS certificate”，如下图：

但是相同的页面使用 FireFox/Safari/Chrome/IE/Edge 等主流浏览器打开都是正常显示的。

调试代码，发现是 WebKitWebView 的 on_load_failed_with_tls_errors 回调函数返回了错误 G_TLS_CERTIFICATE_GENERIC_ERROR（64），如下图：

于是安装 Gnome 官方的浏览器 Epiphany 进行测试，该浏览器底层也是调用 WebKit2GTK，在 ubuntu 24.04 系统，可以执行如下命令进行安装：

$ sudo apt install epiphany-browser

1	$ sudo apt install epiphany-browser

打开相同的页面，同样报错，显示服务器不可信。

由于 WebKit2GTK 底层的 TLS 通信调用库调用的是 GnuTLS 。于是尝试通过命令行对 TLS 证书认证过程进行验证，执行如下命令：

$ sudo apt install gnutls-bin

$ gnutls-cli www.xxxx.com
Processed 146 CA certificate(s).

可以看到，网站的根证书无法通过 GnuTLS 的验证，原因在于网站的证书链中的根证书使用的 RSA-SHA1 签名，该类型签名存在 “弱哈希算法签名的SSL证书(CVE-2004-2761)漏洞” 进而被 GnuTLS 拒绝。

针对此问题的更详细的描述参考 GnuTLS 文档 8.2 Disabling algorithms and protocols 。

针对此问题的解决方法：

联系网站，更新证书，重新以 RSA-SHA256 签发证书。由于是公司内部网址，因此联系网络更新即可；
应用内嵌网站证书，通过 webkit_web_context_allow_tls_certificate_for_host 要求 webkit 通过提供的证书进行网站验证。此种情况适用于 APP 内嵌自己网站页面的情况，同样适用于自签名证书的情况；

如果纯粹测试，可以在加载页面之前调用

// 网站证书存在问题，此处仅为测试场景下，临时关闭TLS证书验证
auto context = webkit_web_view_get_context(WEBKIT_WEB_VIEW(web_view_));

// 低版本 4.0
webkit_web_context_set_tls_errors_policy(context, WEBKIT_TLS_ERRORS_POLICY_IGNORE);

// 高版本 4.1
auto manager = webkit_web_context_get_website_data_manager(context);
webkit_website_data_manager_set_tls_errors_policy(manager, WEBKIT_TLS_ERRORS_POLICY_IGNORE);

// 网站证书存在问题，此处仅为测试场景下，临时关闭TLS证书验证

auto context = webkit_web_view_get_context(WEBKIT_WEB_VIEW(web_view_));

// 低版本 4.0

webkit_web_context_set_tls_errors_policy(context, WEBKIT_TLS_ERRORS_POLICY_IGNORE);

// 高版本 4.1

auto manager = webkit_web_context_get_website_data_manager(context);

webkit_website_data_manager_set_tls_errors_policy(manager, WEBKIT_TLS_ERRORS_POLICY_IGNORE);

要求 webkit 无视证书错误。此方法生产环境不可取，非常不安全，仅可用于内部测试；

此方案目前测试已经不可用：~~调用 gnutls_sign_set_secure_for_certs API 许可部分不安全的证书签名算法~~

// pkg_check_modules(GnuTLS REQUIRED IMPORTED_TARGET gnutls>=3.7.3) 
// target_link_libraries(${BINARY_NAME} PRIVATE PkgConfig::GnuTLS)

// #include <gnutls/gnutls.h>

gnutls_sign_set_secure_for_certs(GNUTLS_SIGN_RSA_SHA1, 1);

// pkg_check_modules(GnuTLS REQUIRED IMPORTED_TARGET gnutls>=3.7.3)

// target_link_libraries(${BINARY_NAME} PRIVATE PkgConfig::GnuTLS)

// #include <gnutls/gnutls.h>

gnutls_sign_set_secure_for_certs(GNUTLS_SIGN_RSA_SHA1, 1);

~~相对来说，联系不上网站的情况下，又需要在保证安全的前提下，尽量兼容网站，推荐此种方式；~~

自行接管证书验证过程，实现比较复杂，极其容易产生安全漏洞，不建议；

VSCode GDB调试控制台报错"-var-create: unable to create variable object"

背景

在使用 Visual Studio Code (1.97.2) 进行 GDB 调试时，想使用 x 命令看一下某地址处的数值。出现如下报错：

-var-create: unable to create variable object

1	-var-create: unable to create variable object

解决方案

其实，在刚刚开始调试程序时，就以黄色字体给出了解决方案。

Execute debugger commands using "-exec <command>", for example "-exec info registers" will list registers in use (when GDB is the debugger)

1	Execute debugger commands using "-exec <command>", for example "-exec info registers" will list registers in use (when GDB is the debugger)

也就是说：

如果是想查看某个变量的值，直接在输入框里输入变量名就好了；
如果要执行GDB命令，则需要加-exec前缀，如下图：
