What output does MD5 give me?
32 hex characters. The same input always yields the same digest. You cannot reverse it to recover the input.
Is MD5 free, and is my input private?
Yes — Your input is processed in memory for this request only. It is not saved to disk or the database, and it is cleared after the tool finishes.
Is MD5 fine if I only use it as a cache key?
Accidental collisions are unlikely for casual cache keys, but attackers can forge MD5 collisions on purpose. Do not use it for security decisions.
