About MD4 Hashing
What is MD4?
MD4 (Message Digest Algorithm 4) is a cryptographic hash function developed by Ronald Rivest in 1990. It produces a 128-bit (16-byte) hash value, typically rendered as a 32-digit hexadecimal number.
Security Note
MD4 is considered cryptographically broken and unsuitable for security applications due to vulnerabilities. It's shown for educational purposes and compatibility with legacy systems only.
How It Works
The algorithm processes input in 512-bit blocks, using a series of bitwise operations, modular additions, and logical functions to create a unique fixed-size output.
Historical Context
MD4 was the predecessor to MD5 and influenced the development of later hash functions. It was widely used in the early 1990s before vulnerabilities were discovered.
