Yeah, nobody cares to spoof my torrent's MD5s, my torrents are crap btw
The fact is, an algorithm is said to be secure if its impossible to generate identical hash strings, from different source, which is not the case of MD5. Also MD5 hash can be decrypted with rainbow table. I reakon we will be moving to SHA256 in near future, so what I was saying is to get yourself be familiar with SHA256 is not a bad idea
