which supports 128-bit and 256-bit output. It was named after the [[Ancient Egypt|Egyptian]] [[Pharaoh]] [[Sneferu]], continuing the tradition of the [[Khufu and Khafre#Khufu|Khufu]] and [[Khufu and Khafre#Khafre|Khafre]] [[block cipher]]s.


The original design of Snefru was shown to be insecure by [[Eli Biham]] and [[Adi Shamir]] who were able to use [[differential cryptanalysis]] to find hash collisions. The design was then modified by increasing the number of iterations of the main pass of the algorithm from two to eight. Although differential cryptanalysis can break the revised version with less complexity than [[brute force attack|brute force search]] (a certificational weakness), the attack requires <math>2^{88.5}</math> operations and is thus not currently feasible in practice.<ref>{{cite paper |author=[[Eli Biham]] |date=2008-07-19 |title=New Techniques for Cryptanalysis of Hash Functions and Improved Attacks on Snefru |publisher=Springer Berlin/Heidelberg |url=http://www.springerlink.com/content/208q118x13181g32/ }}</ref>

Catrina Le is what's shown on her birth qualification though she doesn't extremely like being called like that. Her job would be a cashier but very quickly her husband and her will start their own business. To drive is something your she's been doing best. For years she's been living on the inside Vermont.
