Admittedly, restricting strong encryptions by the law enforcement and national security agencies do have some advantages toward crime fighting. However, the law enforcement and national security agencies can’t deny people’s right to protect their own privacy.

Singh noted: ”Civil libertarians argue that the widespread use of encryption is essential for guaranteeing the right to privacy.” Without strong encryption, people’s data will be exposed to everyone. People’s personal information online or the messages they sent all rely heavily on encryption to be kept as their own privacy. Would the world be better if the database of the giant companies is put online without encryption? Will that be beneficial for fighting crimes? Definitely not. Criminals will have more targets to attack. Also, with knowledge of encrypting, the public can even help the police or national security agencies to fight the crime. Restricting encryption on the public can’t stop the criminals from using them due to the high level of technology they have nowadays as Singh claimed in the book. In general, restricting encryption methods from the public is definitely not making the world better or safer.

On the other hand, the government can’t just forbid others to use or learn encryption and monitor the public at the same time. Singh wrote about the unjustified wiretaps utilized by Presidents Lyndon Johnson and Richard Nixon. Edward Snowden also showed the wiretapping ways used by the government to control the public. Under these circumstances, people should have their rights to learn about these encrypting methods used by the government instead of being restricted to getting in touch with it.
