What is MD5?

MD5 (Message Digest Algorithm 5) is a widely used cryptographic hash function that produces a 128-bit (16-byte) hash value, typically rendered as a 32-character hexadecimal number. It was designed by Ron Rivest in 1991 as a successor to MD4.

Key characteristics:

  • Deterministic: The same input always produces the same hash
  • Fast computation: Quick to compute for any given input
  • Avalanche effect: Small changes in input produce drastically different outputs
  • Fixed output size: Always produces a 128-bit hash regardless of input size
  • Collision vulnerable: Known vulnerabilities make it possible to find collisions

Security status: ⚠️ MD5 is cryptographically broken and should not be used for security-critical applications. Collision attacks were demonstrated in 2004, and practical collision generation became feasible with modern computing power.

Common uses (current and historical):

  • File integrity verification (non-security critical)
  • Checksums for data corruption detection
  • Legacy systems requiring MD5
  • Database key generation (non-cryptographic)
  • Some older protocols and systems

Recommended alternatives:

  • SHA-256 or SHA-3 for new applications
  • SHA-512 for high-security requirements
  • BLAKE2 for high-performance applications
