Collisions for Hash Functions MD4, MD5, HAVAL-128 and RIPEMD. 安全焦点的讨论: https://www.xfocus.net/bbs/index.php?act=ST&f=2&t=39807 个人理解: 1.首先破解这个东西对硬件要求比较高,一般的人是不能达到的.“在IBM P690主机上”,光这个ibm p690现在还不是普通用户的工具; 2。该算法只是说重新得...
In this paper we analyse the security of the SHA-3 candidateARIRANG. We show that bitwise complementation of whole registers turns out to be very useful for constructing high-probability differential characteristics in the function. We use this approach to find near-collisions with Hamming weight 32...
RC4-Hash is a variable digest length cryptographic hash function based on the design of the RC4 stream cipher. In this paper, we show that RC4-Hash is not collision resistant. Collisions for any digest length can be found with an expected effort of less than 29compression function evaluations....

The paper "Cryptanalysis of the Hash Functions MD4 and RIPEMD" by Wang et al details a cryptanalytic attack that lets us find collisions in 2^8 or less. Given a message block M, Wang outlines a strategy for finding a sister message block M', differing only in a few bits, that will ...
“: Had I never known Opie, I might not dislike Dopey. Since I do, however, I find Dopey to be a vastly inferior and annoying UI element, for several reasons: 1. Dopey can’t get to a folder directly. Most of my files are nested four or five levels down from My Documents. When...
For this reason, issuance of the LOCK statement and subsequent testing of the &SYSLCKRC macro variable is the only way to assess lock status through the LOCK statement. As discussed below, lock status also can be assessed reliably through the OPEN and FOPEN functions, which can be implemented...
