Depends on how they got the source. They may know it's one of 5 possible choices because of the person who sent (or received) it. If it's just found on a disk in a garbage dump with no connections to anyone, it's a bit tougher. But every algorithm has some statistical signature and if you've got enough cipher text you can compare that signature with known algorithms to home in on fewer choices.
Do you have any references for this? A quick google search was less than revealing. Thanks in advance.
Patience, persistence, truth, Dr. mike
