Web3 feb. 2016 · MD5 is a hash function – so yes, two different strings can absolutely generate colliding MD5 codes. In particular, note that MD5 codes have a fixed length so the possible number of MD5 codes is limited. The number of strings (of any length), however, is definitely unlimited so it logically follows that there must be collisions.
