Software

• HashClash project: an open-source C++ framework for MD5 & SHA-1 differential path construction and chosen-prefix collisions for MD5, 2009-2012.
  http://code.google.com/p/hashclash.
   
  
• DBLP BibTex: a BibTeX aid program that can automatically download citations and cross references from the DBLP Computer Science Bibliography and the Cryptology ePrint Archive and add them to your BIB file.

• Visual Cryptography: split a black&white image file into two images that seperately look like random static. However, put them on top of each other when printed on transparents and the original image becomes visible.
