Crypt::PW44 - Perl password generator - generate 44-bit passwords using OPIE dictionary from RFC 1760.
# In perl script:
use Crypt::PW44 qw(generate_password);
# 44 bit (4 word) password
$output = generate_password(pack("Ll",int(rand(2**32)),int(rand(2**16))),3);
# $output = generate_password($random_binary_data,$number_of_ascii_text_words_minus_1);
# return value is N-word password of ascii text, with space delimiters between words
This module contains a simple password generator, based on the S/Key calculator (as described in RFC 1760) implemented in Perl. It exports the function generate_password.
This was inspired by the XKCD web comic "Password Strength", permalink http://xkcd.com/936/ .
perl Makefile.PL make make test make install
Given two arguments, uses provided entropic data, computes the hash value, and returns it as a string containing N+1 words separated by spaces. The meanings of the arguments is as follows:
User/script-provided random data, must be binary, and more than N*11 bits in size
AKA "N". Counting from zero, not 1, is number of ASCII words in the password generated.
