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:

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

MD4 vs Other Hash Algorithms

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.
