* MD4 is described in RFC 1320 (which superceeds RFC 1186). * The MD*5* algorithm is described in RFC 1321 (that's 1320 + 1). * MD4 is very similar to MD5, but not quite similar enough to justify * ...
Abstract: In this paper we construct preimage attack on the truncated variant of the MD4 hash function. Specifically, we study the MD4-39 function defined by the first 39 steps of the MD4 algorithm.
