The meaning of the sentence is that the consequence which is caused by weak encryption is worse than that of no encryption. First of all, a weak encryption can be easily deciphered. Once it has been deciphered, the enemy will get to know the hiding information and know the secret between lines. In the scenario, it causes the failure of Babington’s plan and causes the death of the members and Mary Queen of Scots. Secondly, the weak encryption creates an illusory secure. This means that both Babington and Mary Queen of Scots think their plan will not be reached by their enemy. With this feeling, they just keep on using the same method without doubting the possibility of exposing information to Walsingham. Finally, weak encryption creates secrets compared to no encryption. The enemy will spend more time on decoding it in order to get to the secret and get prepared for the scheme of their enemy.

For the people who want to hide their communications, they must use strong and new cryptographic methods to keep their information from deciphering easily by their enemies. In this story, the method of using frequency of the symbols has already applied at that time. Although Babington uses new symbols and kind of different encryption, Phelippes just uses the frequency method to decipher it. The methods of encryption decide whether the secrets can be easily got by enemy or not. What’s more, the sender and the recipient need to change their encryption from time to time and they also need to make sure the person who send the message is not a spy. With all of these, the possibility of divulging a secret will decrease and creates a safer environment for transfering the secrets.
