Weaknesses in MD4 were demonstrated by Den Boer and Bosselaers in a paper published in 1991 . In August 2004 , researchers reported generating Collisions in MD4 using "hand calculation" {Link without Title} , alongside attacks on later hash function designs in the MD4/MD5/SHA/RIPEMD family. MD4 HASHES The 128-bit (16-byte) MD4 hashes (also termed ''message digests'') are typically represented as 32-digit Hexadecimal numbers. The following demonstrates a 43-byte ASCII input and the corresponding MD4 hash: MD4("The quick brown fox jumps over the lazy dog") = 1bee69a46ba811185c194762abaeae90 Even a small change in the message will (with overwhelming probability) result in a completely different hash, e.g. changing d to c: MD4("The quick brown fox jumps over the lazy cog") = b86e130ce7028da59e672d56ad0113df The hash of the zero-length string is: MD4("") = 31d6cfe0d16ae931b73c59d7e0c089c0 SEE ALSO REFERENCES
