Law Is Not A Science: Admissibility of Computer Evidence and MD5 Hashes

Another day... another hashing discussion:

On the SANS GIAC Alumni list the other day, the question popped up from one of the individuals on the list:

"I'm assuming that this group has had the pleasure to consume the latest research focused on MD5 hash collisions. Discussions about hash collisions seems to carry the same energy as religion and politics. My question is regarding digital evidence and the use of MD5 hashes to establish digital evidence integrity. The use of hashes to ensure digital evidence integrity has legal precedence. However, as more research companies introduce concerns related to MD5 hashes, the courts will at some point, no longer consider this as a valid technology to ensure integrity.
