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 from any input string.

Question 2

Is MD5 secure for passwords?

Accepted Answer

No. MD5 is considered cryptographically broken for password storage. Use bcrypt, scrypt, or Argon2 for passwords. MD5 is still useful for checksums and non-security purposes.

Question 3

Is the same input always the same hash?

Accepted Answer

Yes. MD5 is deterministic — the same input always produces the same 32-character hash output.

Question 4

Can I reverse an MD5 hash?

Accepted Answer

MD5 is a one-way function and cannot be mathematically reversed. However, common passwords can be found via rainbow tables.

Question 5

What is MD5 used for today?

Accepted Answer

MD5 is commonly used for file integrity verification, checksums, and non-security data fingerprinting.
