Task 3: run 'strings server > strings.out' to get a list of strings in server
examine the file strings.out - search for 'key'
Observe an RSA private key shows up
Cut and paste the private key to file 'rsa.key'
run 'openssl rsautl -decrypt -in 952606818.key.enc -out plain -inkey rsa.key
The decrypted contents are in file 'plain'
rsautl: RSA utility for signing, verification, encryption, and decryption.
-in: input file to decrypt
we are given 952606818.key.enc, client, server, libdriver.so
The key is CHH754BYLORPT7KFJQRKFUQCWZV2UK7MUNNR4YRNTABMKFVSK7QA
