About MD5
- • MD5 (Message-Digest Algorithm 5) is a widely used cryptographic hash function
- • Produces a 128-bit (16-byte) hash value, typically rendered as 32 hexadecimal digits
- • Designed by Ronald Rivest in 1991
- • One-way function: cannot be reversed to obtain the original data
- • Deterministic: same input always produces the same hash
- • Fast computation makes it suitable for checksums
Common Uses:
- • File integrity verification (checksums)
- • Non-critical data deduplication
- • Legacy system compatibility
- • Database indexing (non-security critical)
- • Cache key generation
- • Software distribution verification
Important Security Warning:
⚠️ MD5 is NOT secure for cryptographic purposes!
- • Vulnerable to collision attacks (different inputs producing same hash)
- • Should NOT be used for passwords or security-critical applications
- • Only use for non-security checksums and legacy compatibility
- • For security, use SHA-256, SHA-512, or SHA-3 instead
- • For password hashing, use bcrypt, scrypt, or Argon2
