You are working with that specifically requires MD5.

Cryptographically broken. It is vulnerable to "collision attacks," where two different inputs produce the exact same hash.

You need to verify quickly (e.g., cloud storage, backups).

You want a modern, well-maintained algorithm optimized for 64-bit systems. Use MD5 if:

If you need security , skip both and use SHA-256 or BLAKE3 . Final Verdict

MD5 (Message-Digest Algorithm 5) was designed in 1991 by Ronald Rivest. For decades, it was the gold standard for verifying file integrity and storing passwords. 128-bit hash value.

A non-cryptographic hash. While it isn't "broken" in the same way MD5 is, it was never meant to resist malicious attacks. However, its dispersion and randomness (passing the SMHasher test suite) are actually superior to MD5 for general data distribution. Collision Resistance

Are you looking to implement one of these in a or for a particular project ?
