What is the hash value output size of MD4?

MD4 is a cryptographic hash function that produces a hash value output of 128 bits, which is equivalent to 16 bytes. This output size is a defining characteristic of MD4, making it suitable for various applications where a fixed-size output is needed. The algorithm processes input data in blocks and utilizes a specific sequence of operations to generate a digest that is uniquely tied to the input. Since the design of MD4 allows for this output size, it has been widely referenced and used in various cryptographic protocols and applications, although it is now considered less secure compared to more modern hash functions. Understanding the output size is crucial for recognizing the limitations and best practices when working with hash functions in algorithm design and cryptography.
