Questions
Is MD5 safe to use?
Not for anything security-related. Practical collision attacks against MD5 have existed since 2004, and it must never be used for password storage, digital signatures or integrity checks against a motivated attacker. It remains acceptable as a fast, non-adversarial checksum, for example detecting accidental file corruption or as a cache key.
What should I use instead for passwords?
A deliberately slow, salted password hash: bcrypt, scrypt or Argon2. General-purpose digests like MD5 and SHA-256 are designed to be fast, which is exactly the wrong property for password storage.
