Open Source Unix Shell Password Generators

PROJECT MOVED: https://github.com/vstavrinov/rpg ----------------------------------------------------------------------- This shell script generate passwords easy to read and remember, but still strong enough. This is achieved by some restrictions. Some letters, digits, and letter combinations are excluded. No consecutive vowel. No more then 2 consecutive consonant. No consecutive consonant before and after digit. Main stream is lower case letters. Chance to include digit and upper case letters may be adjusted.

- Suggests multi-word passwords, so-called low-complexity passwords. - Low-complexity passwords consist only of words, all in lowercase characters. Lowercase characters can be typed on virtually any keyboard worldwide. - A low-complexity password is easy to memorize, in contrast to passwords that demand uppercase chars, digits, and special characters. - Low-complexity passwords can be mathematically shown to be very strong, even in the face of very skeptic assumptions. - The passwords consist of 4 words (default) of fixed length 6 (default). The word separator is '-' (default). - The source of the words is the Linux system dictionary (about 100,000 words). - The tool can give the entropy of the password scheme (calculated in a conservative way). - It can also give the entropy of the dictionary the password scheme is based on (calculated in a conservative way). - Its defaults can be shown via an option and can be modified with command line options.
