Hi, I'm Theodore Tikhonov, a student of an American college.
I've been suspicious about my fellow student, Eric Grimm, "buying off" credits from his professor, Dr. Charles D. Cooper.
I haven't been able to secure any evidences of such fraud, but recently I've intercepted an encrypted email between these two. You can take a look at its message body here.
Can you crack the code and reveal what these guys are up to?
Thanks.
Oh, by the way, this seems to be the algorithm used to encrypt the message: http://deal.tkbctf.info/
