passphrase-generator
Generate a set of random passphrases for you to choose from.
...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 -

Entropy Monitor
Monitor of the available entropy stored within the Linux kernel
...Without random numbers these programs would generate the same results every time they run. High security uses for entropy would be applications that create cryptographic keys. Even after the key is eventually replaced, everything it was used to encrypt remains only as safe as the entropy used to generate the key. This monitor checks the amount of available entropy and informs the system adminstrator about possible bottlenecks on his system. -

SecQua
SecQua tries to quantify the security of a given Information System
...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. Patsakis, Gregory Chondrocoukis, D. Mermigas, S. Pirounias, The role of weighted entropy in security quantification, International Conference On Information Security And Artificial Intelligence (ISAI 2010), December 17-19, 2010, Chengdu, China. *C. Patsakis, D. Mermigas, S. Pirounias, N. Alexandris, E. Fountas, Towards a formalistic measuring of security using stochastic calculus, 3rd IEEE International Conference on Computer Science and Information Technology (ICCSIT 2010), Chengu, China, 9-11 July 2010. -

MandelHash
MD5 hash used to position and color two overlaid Mandelbrot sets.
I'm using an MD5 hash of a username and password field to generate some entropy which is used to generate color pallets and positions / scaling of two Mandelbrot sets. These two images are overlaid to create interesting pictures which represent the entered credentials. I'm interested in all things security, this is mostly just for fun, but could possibly be used to help users identify mistakes in their password entry prior to submission and enforce a tighter failed password lockout policy. ... -

SweetOnionCCG2PTBConverter
A tool that converts CCGBank to PTB
Conversion between different grammar frameworks is of great importance to comparative performance analysis of the parsers developed on them. This tool can convert CCG derivations to PTB trees by using Max Entropy models as well as visualizing the tree graphs. The main technical innovation presented here is the effective conversion method which achieves a F score over 95%. -

tickets
pythonic kerberosish ticket system: easy to use, easy to subclass
A SecureTicket, or Ticket, consists of salt, hash, valid_until, public_flags, flags, data and "invisible" hashed entropy. Tickets are symmetrically signed using SHA256-HMAC. Fields 'valid_until', 'flags' and 'data' may be optionally encrypted using AES128-CBC or TripleAES128-CBC. Values 'data' and 'entropy' may consist of arbitrary objects which are transparently pickled(serialized), optionally gzipped and of course securely signed. Specific implementations are included: FormTicket: provides core implementation of state-less Cross Site Request Forgery protection. ... -
