如何使用github
1) 通过Git Bash 生成公钥、私钥(RSA非对称加密算法)
ssh-keygen -t rsa -b 4096 -C "your_email@example.com"
$ ssh-keygen ? Too many arguments. usage: ssh-keygen [-q] [-b bits] [-t dsa | ecdsa | ed25519 | rsa] [-N new_passphrase] [-C comment] [-f output_keyfile] ssh-keygen -p [-P old_passphrase] [-N new_passphrase] [-f keyfile] ssh-keygen -i [-m key_format] [-f input_keyfile] ssh-keygen -e [-m key_format] [-f input_keyfile] ssh-keygen -y [-f input_keyfile] ssh-keygen -c [-P passphrase] [-C comment] [-f keyfile] ssh-keygen -l [-v] [-E fingerprint_hash] [-f input_keyfile] ssh-keygen -B [-f input_keyfile] ssh-keygen -D pkcs11 ssh-keygen -F hostname [-f known_hosts_file] [-l] ssh-keygen -H [-f known_hosts_file] ssh-keygen -R hostname [-f known_hosts_file] ssh-keygen -r hostname [-f input_keyfile] [-g] ssh-keygen -G output_file [-v] [-b bits] [-M memory] [-S start_point] ssh-keygen -T output_file -f input_file [-v] [-a rounds] [-J num_lines] [-j start_line] [-K checkpt] [-W generator] ssh-keygen -s ca_key -I certificate_identity [-h] [-n principals] [-O option] [-V validity_interval] [-z serial_number] file ... ssh-keygen -L [-f input_keyfile] ssh-keygen -A ssh-keygen -k -f krl_file [-u] [-s ca_public] [-z version_number] file ... ssh-keygen -Q -f krl_file file ...
Secure Shell key generator 工具,-t 指定加密算法类型(type),-b 指定密钥位数(bit) ,-C 注释(comment)
2)启动 ssh-agent
eval $(ssh-agent -s)
单独执行 ssh-agent -s 会得到命令行,然后再通过eval 执行这些命令行才能真正启动 ssh-agent,有点类似 js里的eval
3) 将私钥添加到 ssh-agent
ssh-add ~/.ssh/id_rsa
如果提示 Could not open a connection to your authentication agent. 说明ssh-agent没有成功启动
4)将公钥 (id_rsa.pub) 添加到 github
Settings -> SSH AND GPG keys -> New SSH key
5)使用 ssh 地址进行clone等操作
git clone git@github.com:witaste/ztest.git
补充:常用工具类所在目录结构
│ git-bash.exe │ git-cmd.exe │ ├─cmd │ start-ssh-agent.cmd │ start-ssh-pageant.cmd │ └─usr ├─bin │ │ ssh-add.exe │ │ ssh-agent.exe │ │ ssh-keygen.exe │ │ ssh-pageant.exe
使用优化
因为每次启动 git-bash ,都需要启动一个新的 ssh-agent ,而且旧的不能用 ,能不能实现自动化呢,就是每次打开 Git Bash 就会自动打开ssh-agent并且自动将私钥添加到ssh-agent,答案是有
第一种方案:
通过 GitHub Desktop 自带的 Git Shell 可自动完成
第二种方案:
添加自动化脚本
在当前用户目录(~)下创建 .profile 文件,内容是
env=~/.ssh/agent.env agent_load_env () { test -f "$env" && . "$env" >| /dev/null ; } agent_start () { (umask 077; ssh-agent >| "$env") . "$env" >| /dev/null ; } agent_load_env # agent_run_state: 0=agent running w/ key; 1=agent w/o key; 2= agent not running agent_run_state=$(ssh-add -l >| /dev/null 2>&1; echo $?) if [ ! "$SSH_AUTH_SOCK" ] || [ $agent_run_state = 2 ]; then agent_start ssh-add elif [ "$SSH_AUTH_SOCK" ] && [ $agent_run_state = 1 ]; then ssh-add fi unset env
第三种方案:
安装TortoiseGit 通过Pageant 软件加载PuTTY 形式的私钥
D:\Program Files\TortoiseGit\bin\puttygen.exe
1)生成 .ppk (可以通过PuTTYgen 生成新的密钥对,也可以load原有的私钥,转换成ppk)
2) 通过 Pageant 工具加载 ppk
补充:tortoiseGit 目录结构
│ ├─bin │ pageant.exe │ puttygen.exe
