About MD4 Hash Algorithm

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 expressed as a 32-character hexadecimal number.

MD4 Hash Characteristics

⚠️ Security Warning: MD4 is considered cryptographically broken and vulnerable to collision attacks. It should not be used for security-sensitive applications. Consider using stronger algorithms like SHA-256 or SHA-3 for security purposes.

Common Uses of MD4

Despite its vulnerabilities, MD4 is still used in some legacy systems and specific applications:

MD4 vs Other Hash Algorithms

Application	Usage
NT LAN Manager	Older versions of Windows used MD4 for password hashing
ED2K file hashing	eDonkey2000 file sharing network uses MD4 for file identifiers
Legacy systems	Some older applications and protocols still utilize MD4

Algorithm	Output Size	Security Status	Common Uses
MD4	128 bits	Broken	Legacy systems
MD5	128 bits	Vulnerable	Checksums, non-crypto uses
SHA-1	160 bits	Vulnerable	Git, legacy certificates
SHA-256	256 bits	Secure	Cryptography, blockchain, certificates

💡 For security-critical applications, always use modern hash algorithms like SHA-256, SHA-3, or BLAKE2. MD4 should only be used for compatibility with legacy systems.
