红帽全球峰会C.5. 常用后安装任务
下面这部分是关于常用后安装任务的论述
C.5.1. 设定随机生成的密钥作为访问加密块设备的附加方法
复制链接链接已复制到粘贴板!
以下部分论述的是如何生成密钥和添加密钥。
C.5.1.1. 生成密钥
复制链接链接已复制到粘贴板!
这将在文件
$HOME/keyfile 中生成 256 位密钥。
dd if=/dev/urandom of=$HOME/keyfile bs=32 count=1 chmod 600 $HOME/keyfile
dd if=/dev/urandom of=$HOME/keyfile bs=32 count=1
chmod 600 $HOME/keyfile
C.5.1.2. 在加密设备中将该密钥添加到可用密钥插槽中
复制链接链接已复制到粘贴板!
cryptsetup luksAddKey <device> ~/keyfile
cryptsetup luksAddKey <device> ~/keyfile
