Message-Digest Algorithm 4 is a hash function published by Ronald L. Rivest in 1990.
The algorithm generates a 128-bit check digit that is written as a 32-digit hexadecimal number.
MD4 is now no longer considered secure, since it is possible with manageable effort to generate different messages that have the same MD4 hash value.
GC Wizard offers the following hash length
