Break the encrypted file you have been given. with a a clearly argued explanation of how you go about breaking the code as well as for correct identification of the key and recovery of the plaintext.
The task will require bit-level programming, a basic appreciation of encryption concepts..The key is 8 bits long.I will upload a java and C program for it.
I need a report containing a clear explanation of how you broke the code and the value of your broken key. Append printouts of any utility program you wrote to help you do this.

Hi, This is a very easy assignment as the key space is very small. Also, we can use frequency analysis to crack this encryption. I can do this for you quickly once you send me the encrypted file. Regards, Nilanj Lagi

Please reply so that we can discuss on your project. I work alone from my small office at home. I believe writing is not only about paying my bills but my ability to ensure that clients are getting high quality conten Lagi
Hi there. I checked this cryptography project and I can handle it. I have 10 years of programming experience. Thank you very much.
Hi, I can help you. The only way of encryption is using frequency analysis. So we decode the file with all possible combinations and do a frequency analysis of each string.
This can be done by writing a simple program that mounts a brute force attack on encrypted file. Since encryption key is only 8 bit long, total key combinations can be 2^8 = 256. By analyzing output files exact key, c Lagi
Hi. I can provide a clear English explanation of why this is an extremely weak encoding, and easily broken. I don't know if you intended to include a sample encrypted file - I didn't see one posted. I can also suggest Lagi
