It has four +rounds instead of three, and incorporates other revisions based on a +year's worth of collected comments on the MD4 algorithm. For example, +the input access patterns in rounds two and three have been improved, +and the rotation amounts have been optimized for maximum ``avalanche +effect.'' The additive constants have been made unique in each step, +and an additional dependence of each step on the previous one has been +added. + +These changes cause MD5 to be somewhat slower than MD4. We estimate +that MD5 will typically run about 15-30% slower than MD4, depending on +the degree to which the versions of MD4 and MD5 have been optimized. +The more they are both optimized, the greater the percentage +difference in speed. An optimized version of MD5 on a Sun +SparcStation runs at about 890 Kbytes/second. + +Why MD5? While we do not know of any way to ``break'' MD4, we feel +that MD4 is being pressed into service far too quickly for such an +``aggressive'' design. We have been surprised at the speed with which +MD4 is being designed into products. MD5 is ``MD4 with seatbelts'' +and thus, as a more conservative design, is more suitable for rapid +deployment. + +It is the intent of RSA Data Security to use MD5 in its products and +standards instead of MD4. We recommend that our customers generally +do the same, unless there is an overwhelming need for the higher speed +of MD4. Copies of the MD5 algorithm, including a reference +implementation in C, are available from the company.
