“database” directory. Depending on the application, it can be in the following places by default: • ~/.pki/nssdb/pkcs11.txt This is where the system-provided libnss3 library will look by default. • ~/snap/firefox/common/ the system NSS libraries. For these examples, we will be using the configuration file located in ~/.pki/nssdb/pkcs11.txt. As noted before, depending on the application this file can be in another directory which has the necessary tools we will need: sudo apt install libnss3-tools If you don’t have a ~/.pki/nssdb directory yet, it will have to be created first. For that, we will use the certutil command,

more than just pre-shared keys OpenVPN makes it easy to setup and use a Public Key Infrastructure (PKI) to use SSL/TLS certificates for authentication and key exchange between the VPN server and clients Infrastructure Setup The first step in building an OpenVPN configuration is to establish a PKI (public key infrastructure). The PKI consists of: • a separate certificate (also known as a public key) and private

文件（应用程序执行或普通文件访问时进行签名校验）； 运行阶段（软件包安装）：包管理组件 ->RPM 软件包（软件包安装时进行签名校验）。 为支持“开箱即用”的安全启动能力，核心是在 openEuler 社区建立以 PKI 为基础的软件构建签名体系，在软件构建阶段，自 动为目标文件添加数字签名，并在关键组件中预置公钥证书，从而在用户安装 openEuler 镜像后，可以直接开启相关的签名校验机 制，提升系统安全性。
