Why is MD5 useful?

Hash algorithm such as MD5 is a one-direction algorithm, which means it's not reversable. This character makes MD5 very useful in making "fingerprint" on a file, MD5 value of a file can prove a file haven't been modified. Hash algorithm also used in password protection. Combine a "salt" and your original password, the final value stored in website database is not reversable, means hackers can't recover your password even if the database is leaked.

Is MD5 secure and should I keep using it?

The first attack is called "rainbow tables". It's a very large database include short simple string with corresponding MD5 value. For example, when you check the rainbow table for "FC5E038D38A57032085441E7FE7010B0", you can find its original string is "helloworld". Rainbow tables can successfully decrypt MD5 if the original string is short.

The second attack is based on MD5's fundamental algorithm, more and more website switched to SHA256 or SHA512 in recent years. Even though many websites are still using MD5, which leaves big potential catastrophe in Internet security.
