In the first chapter of The Code Book by Simon Singh, he states that “a weak encryption is worse than no encryption at all”. A weak encryption is worse than no encryption at all because the sender and receiver of the message believe that the message is secure. A weak encryption leads to a false sense of security. If someone was to send a message with no encryption, they would know that their message was floating around and would be more cautious. People that send encrypted messages should always be mindful of what information their message contains. Over time many messages can be decrypted, and a sender of an encrypted message should remain mindful of that. No one should put all of their trust into a encryption since the message could possibly be deciphered. People that want to keep their messages secret should keep their messages very vague even if they are encrypted. There is always a chance that a message can be decrypted, so the sender should not only rely on a encryption to make sure that their message is secure. Mary Queen of Scots should have been vaguer with the messages that she sent. Since she truly believed that her messages would not be decrypted, she was not withholding the information that she sent. Her trust in the encryption led to her execution.
