linux下的命令行密码生成器

linux下的命令行密码生成器

1.pwgen
描述：Automatic Password generation
 pwgen generates random, meaningless but pronounceable passwords. These
 passwords contain either only lowercase letters, or upper and lower case mixed,
 or digits thrown in. Uppercase letters and digits are placed in a way that
 eases remembering their position when memorizing only the word.

2.makepasswd
描述：Generate and encrypt passwords
 Generates true random passwords by using the /dev/urandom feature of Linux,
 with the emphasis on security over pronounceability.  It can also encrypt
 plaintext passwords given in a temporary file.

3.apg
描述：自动密码生成器 - 独立版本
 APG (自动密码生成器) 是一个用于生成随机密码的工具集。它可以生成一些指定
 类型的随机字并输出到标准输出。这个二进制包仅包含 apg 的独立版本。 优点:
 * 内建 ANSI X9.17 RNG (随机数生成器)(CAST/SHA1)
 * 内建密码质量检查系统 (目前已经支持通过 Bloom 过滤器快速访问)
 * 两种密码生成算法:
   1. 可拼读密码生成算法 (遵照 NIST FIPS 181)
   2. 带有 35 个可配置操作模式的随机字符密码生成算法
 * 可配置的密码长度参数
 * 可配置的生成密码数量
 * 可以使用用户指定的 RNG 初始化字符串
 * 支持 /dev/random
 * 可以使用 crypt() 生成密码, 并把它们打印出来作为附加输出
 * 有特殊参数，用于把 apg 用于脚本编写
 * 可以为网络版本把生成密码请求记入日志
 * 可以使用 tcpd 控制 APG 服务的访问
 * 可以从各种联网主机 （Mac, WinXX 等) 访问密码生成服务
 * 可以强制远程用户只能生成某种类型的密码
 apg 的客户机/服务器版本被刻意地去掉了。

另外附加两个常用的密码管理工具
1.keepass2
描述：Password manager
 KeePass is a easy-to-use password manager for Windows, Linux, Mac OS X and
 mobile devices. You can store your passwords in highly-encrypted databases,
 which can only be unlocked with one master password and/or a key file. A
 database consists of only one file that can be transferred from one computer to
 another easily. KeePass can import data from various file formats. The password
 list can be exported to various formats, including TXT, HTML, XML and CSV
 files.

2.keepassx
描述：Cross Platform Password Manager
 KeePassX is a free/open-source password manager or safe which helps you to
 manage your passwords in a secure way. You can put all your passwords in one
 database, which is locked with one master key or a key-disk. So you only have
 to remember one single master password or insert the key-disk to unlock the
 whole database. The databases are encrypted using the algorithms AES or
 Twofish.
