Search Results for "entropy"

...The passphrase-generator defaults to only 3 words instead of the 4 suggested by XKCD, but uses a larger dictionary found in many unix like systems at /usr/share/dict/words. It also provides estimates for the entropy of the generated passphrases. The randomization is based on /dev/urandom and SHA1. See http://xkcd.com/936/ for an entertaining take on passwords vs. passphrases. See my post in stackoverflow for links to other solutions and discussions on passphrases vs passwords: http://stackoverflow.com/a/12646320/1148030

...The approach is vulnerability driven and in order to get as much unbiased results, it makes use of the National Vulnerability Database. This work is mainly based on the following publications: *C.

A cryptographically secure random password generator for Linux written in python and GTK 2.0.

BeeCrypt is an ongoing project to provide a strong and fast cryptography toolkit. Includes entropy sources, random generators, block ciphers, hash functions, message authentication codes, multiprecision integer routines, and public key primitives.

The Entropy Gathering Daemon is a portable perl script which provides a source of randomness on systems that lack an in-kernel /dev/random. GnuPG, OpenSSH, and the OpenSSL toolkit can use EGD to seed their random number generators.
