The Proton Mail Blog has an article that serves as a tutorial about backdoors in encryption and the dangers of using any encrypted data that contains a “backdoor” for use by law enforcement personnel and others. In short, the use of “backdoors” makes it easier for hackers, credit card thieves, and others to spy on you, not more difficult.
The article states: “With appeals to ‘national security,’ governments around the world are pushing for encryption backdoors that would allow them to break into the secure data of suspected criminals. Simply put, this is a terrible idea.”
If you do not fully understand backdoors and the dangers of using them, you need to read the article by Ben Wolford at https://protonmail.com/blog/encryption-backdoor.
