MD5 is a 128 bit random number no one would ever have thought would collide. 64 bits is peanuts especially when message types are being defined dynamically

- remram 5y agoMD5 is safe against unintentional collisions.
- NavinF 5y agoDude that’s why I said “unintentional collisions”. Of course you can get intentional collisions. The security model here assumes that anyone that wants to know your message’s ID can just ask. Did you know that the Internet Protocol uses a 4-bit header to specify the format (v4 or v6) of the rest of the message? They should have used 128 bits. What a bunch of fools.
