Assignment #10
OBJECTIVE: Decrypt the Message.
DESCRIPTION: It's been quite some time since we assigned you any challenge. But finally, here it is - a very important one. Read carefully.
The IP address of COATIS indeed turned out to be a very crucial piece of information. Our cyber security personnels worked hard as the IP itself was non functional, but after a series of highly intelligent efforts, they traced it to the original IP of COATIS.
The delay in your assignment was also, in part, due to these efforts. Further, we needed the permissions of the court for our next step. It also took laborious legal efforts and lengthy time. But in the end, we got the permissions and took the necesary step. We intercepted the emails of COATIS, and now have those in our possession.
We have sent to you one of those emails, but it is encrypted using DES. The message containing the DES key itself, is encrypted using RSA. The details are attached herewith.
Decrypt the RSA message, Get the DES key, Decrypt the DES email, and submit the plaintext to us soon.
CIPHER INFO: DES for plaintext. RSA for key
