What is MD5?
MD5 (Message Digest Algorithm 5) is a widely used hash function that produces a 128-bit (32-character hexadecimal) digest. Although MD5 is no longer considered cryptographically secure for security applications (collision attacks have been demonstrated), it remains useful for non-security purposes such as file integrity checksums, cache busting, and data deduplication.

Frequently Asked Questions
Is MD5 still safe to use?
MD5 is not safe for security-sensitive applications such as password hashing or digital signatures because collision attacks are computationally feasible. For data integrity checks where security is not a concern — such as verifying a downloaded file matches a known hash — MD5 remains fast and practical.
What is the output length of MD5?
MD5 always produces a 128-bit (16-byte) digest, displayed as 32 hexadecimal characters.
What should I use instead of MD5 for passwords?
Use bcrypt, scrypt, or Argon2 — algorithms specifically designed to be slow and resist brute-force attacks. For general-purpose hashing, SHA-256 or SHA-512 are secure alternatives.
What is an MD5 hash used for?
Common uses include: verifying file downloads, generating cache keys, checksumming data chunks in distributed systems, and historically password storage (no longer recommended).
