介绍
本文主要介绍在Ubuntu Linux上如何创建一个简单的脚本来保护您的密码信息. 脚本由
Duane Odom编写, 使用了Dialog会话和GnuPG密码程序. 大致的过程是: 首先运行脚本,
然后屏幕显示一个对话框, 用户要求输入主口令, 然后解密指定文件的所有信息, 接
下来在文本编辑器中打开文件. 当编辑器关闭后, 脚本重新加密密码文件.
平台: Ubuntu 6.06 LTS
# cat /etc/lsb-release
DISTRIB_ID=Ubuntu
DISTRIB_RELEASE=6.06
DISTRIB_CODENAME=dapper
DISTRIB_DESCRIPTION=”Ubuntu 6.06 LTS”
工具: Dialog和GnuPG
Dialog是一个基于ncurses库的图形工具, 提供文本消息和输入对话框服务. GnuPG是一
个开源版的OpenPGP标准实现.

照片什么的都是在家里两份硬盘备份，只有偶尔需要共享的放到dropbox上。网络存储
空间还是太小，我的照片都快2TB了。

gpg --output x.pgp --encrypt --recipient [email protected] x.txt |

7zip可以计算sha1)
我这次下载lyx, 网站上让我经过好几步来进行gpg验证，至于这么麻烦嘛。
We provide gpg-signed tarballs and binaries. Our GPG key ID is
0xDE7A44FAC7FB382D (LyX Release Manager). The signatures are found next to
the tarballs and binaries.
To initially import our key via GnuPG, do this:
gpg --recv-keys FE66471B43559707AFDAD955DE7A44FAC7FB382D
Attention: Please be careful to use this full fingerprint, spoofed version
of shortened fingerprint is already in the wild and it... 阅读全帖 |
