Question 1

What is MD5?

Accepted Answer

MD5 (Message-Digest Algorithm 5) is a widely used cryptographic hash function that produces a 128-bit (32 hex character) hash value. It's commonly used for file checksums and data integrity verification.

Question 2

Is MD5 safe for passwords?

Accepted Answer

No. MD5 has known collision vulnerabilities and is considered cryptographically broken for security use. Never use MD5 to hash passwords — use bcrypt, Argon2, or PBKDF2 instead. MD5 is fine for non-security checksums.

Question 3

Does the same input always produce the same MD5 hash?

Accepted Answer

Yes. MD5 is a deterministic function — identical input always produces identical output, which is why it's useful for verifying file integrity.
