GPG在Linux上的应用主要是实现官方发布的包的签名机制 GPG分为公钥及私钥 公钥:顾名思意,即可共享的密钥,主要用于验证私钥加密的数据及签名要发送给私钥方的数据 私钥:由本地保留的密钥,用于签名本地数据及验证用公钥签名的数据 实现原理(以Red Hat签名为例): 1>RH在发布其官方的RPM包时(如本地RHEL光盘及FTP空间包),会提供一个GPG密钥文件,即所谓的公钥 2>用户下载安装这个RPM包时,引入RH官方的这个RPM GPG公钥,用来验证RPM包是不是RH官方签名的 导入GP

1 gpg 这是一种公钥.私钥机制. 2 rpm包的格式 rpm包由四部分构成,lead.signature.header和archive构成. 这里的签名(signature)是加密了的,也就是说,rpm包的发布者事先用gpg的私钥加密了.这个signature是md5. 3 rpm包的gpg key机制即数字签名 目的就是为了防止别人更改了我发布的rpm包. 看rpm包是否被修改的方法.第一,得到发布的包的md5,用公钥解密出原有的md5.第二,计算出我获取的rpm包的md5. 如果两者相同

自从XcodeGhost之后下载软件之后也会先验证一下md5sum,现在发现后面还有gpg签名,于是也开始学习一下. gpg的文件在centos6.4上是默认安装的,其安装使用可以参照ruanyifeng的文章. 这里主要讲一下怎么对下载的文件进行验证. 首先当然是下载安装文件,这次下载的使用wso2的data service server 3.2.1,下载地址. 然后是打开gpg文件,如下图1所示,将这个文件也下载下来 在term下面执行gpg --verify wso2dss-3.2.1.z

概述 GPG是一种加密算法,现在github支持commit使用GPG加密,从而保证提交的commit在传输的过程中没有被篡改. 一.生成GPG密钥 什么是GPG:阮一峰的GPG教程 安装GPG:brew install GPG 生成GPG key:gpg --gen-key,根据提示,生成GPG key,注意:确保邮箱的那项是你github账号认证的邮箱:还有记住输入的密码. 查看GPG key:gpg --list-keys,如下图: 注意:sub:私钥:pub:公钥:黄色的才是GPG ke

这是因为yum安装了旧版本的GPG key造成的,解决办法: rpm --import /etc/pki/rpm-gpg/RPM* Header V3 DSA/SHA1 Signature, key ID解决办法: rpm -ivh vnc-server-4.1.2-14.el5_5.4.i386.rpm --force --nodeps

最小安装: 1. 选择English 2. DATE & TIME 修改好本地时间 SOFTWARE SELECTION默认的Minimal Install就好 INSTALLATION DESTINATION选一下 然后,Begin Installation 3. ROOT PASSWORD设置ROOT密码 USER CREATION设置新用户,勾选Make this user administrator 等待安装完成,点Reboot按钮. 配置静态IPv4: $ systemctl stat
