Cryptanalysts have found weaknesses in which hash algorithm?

Explanation:
Hash functions should resist collisions, meaning it should be extremely hard to find two different inputs that produce the same hash. Cryptanalysts have demonstrated practical collision attacks against MD5, showing it is no longer reliable for security-critical tasks like digital signatures or certificate integrity. In contrast, SHA-512, a part of the SHA-2 family, has not shown practical collisions to undermine its security in real-world use. Because of these findings, MD5 is the one with known weaknesses, making it the best answer. SHA-512 remains considered secure for its intended purposes when used properly.
