1. lets try and break a DES-encrypted message. We have intercepted 2 encrypted messages and we have access to the first 52 bits of the 64-bit key used to encrypt the message. Remember some bits of the 64-bit key are odd parity (this may help you). Use the provided code and add some ability to brute force the last 12 bits (4096 total attempts).

We know the first message decrypts to Our Code, what is the second message?

Encrypted Message 1 = 2a5ec387ecd2c823

Encrypted Message 2 = 3a07cea07f42fc72

First 52 bits of the key = 7269b22156832???

Hint: Use the fact you know what message 1 is to determine the key, then decrypt message 2.
