Linux生成密文密码

1.通过ansible

 ansible all -i localhost, -m debug -a "msg={{ '123456' | password_hash('sha512', 'oldboy') }}"
  localhost | SUCCESS => {
       "msg": "$6$oldboy$MVd3DevkLcimrBLdMICrBY8HF82Wtau5cI8D2w4Zs6P1cCfMTcnnyAmmJc7mQaE9zuHxk8JFTRgYMGv9uKW7j1"
     }

2.通过mkpasswd

 mkpasswd --method=sha-512

3.通过passlib需要python

 yum install -y python-pip
     pip install passlib
     python -c "from passlib.hash import sha512_crypt; import getpass; print(sha512_crypt.using(rounds=5000).hash(getpass.getpass()))"
     Password: 
     $6$rJJeiIerQ8p2eR82$uE2701X7vY44voF4j4tIQuUawmTNHEZhs26nKOL0z39LWyvIvZrHPM52Ivu9FgExlTFgz1VTOCSG7KhxJ9Tqk.

4.通过htpasswd

需要安装“httpd-tools”，安装httpd时会自动安装

 htpasswd -bc ./htpasswd user1 123456

htpasswd命令参数说明:

       -c  Create a new file.  *****
           创建一个密码文件
       -n  Don't update file; display results on stdout.
           不会更新文件; 显示文件内容信息
       -b  Use the password from the command line rather than prompting for it. *****
           免交互方式输入用户密码信息
       -i  Read password from stdin without verification (for script usage).
           读取密码采用标准输入方式,并不做检查 ???
       -m  Force MD5 encryption of the password (default).
           md5的加密算法
       -B  Force bcrypt encryption of the password (very secure).
           使用bcrypt对密码进行加密  
       -C  Set the computing time used for the bcrypt algorithm
           (higher is more secure but slower, default: 5, valid: 4 to 31).
           使用bcrypt algorithm对密码进行加密
       -d  Force CRYPT encryption of the password (8 chars max, insecure).
           密码加密方式
       -s  Force SHA encryption of the password (insecure).
           加密方式
       -p  Do not encrypt the password (plaintext, insecure).
           不进行加密
       -D  Delete the specified user.
           删除指定用户
       -v  Verify password for the specified user.
