I need MD4 algorithm code

Anyway the MD4 algorythm is obsolete, consider using the MD5, or one of the SHA family algorithms. The Crypto++ library[^] implements all of them.

Ron Rivest was co-author of a book on Algorithms in the early 90s that described MD4. It should be available from any good technical library.

It's called: "Introduction to Algorithms, Third Edition" by Cormen, Leiserson, Rivest and Stein.

Failing that look in RFC 1320, it's got all the details you could want, and then some.

Cheers,

Ash

PS: You really don't want to use it, it's been compromised so many times it's not funny.
