Learn How Encryption Works

I don’t know about you but I’m fascinated by cryptography. I want to know how it works, how it can be tested, and most importantly, how it can be used to keep my data private from prying eyes.

In recent years, you’ve probably heard FBI Director Comey talking about the evils of the world “going dark” where the government can’t track everything we do. Personally, I think that’s a great thing. In the United States, we have the Constitution which, in the 4th Amendment, secures us from illegal search and seizure by our government.

The right of the people to be secure in their persons, houses, papers, and effects, against unreasonable searches and seizures, shall not be violated, and no Warrants shall issue, but upon probable cause, supported by Oath or affirmation, and particularly describing the place to be searched, and the persons or things to be seized.

Unfortunately, the U.S. Foreign Intelligence Surveillance Court (what was until recently a secret court making secret interpretations of law) has essentially decided that we no longer have those rights. This is what the FBI, CIA, and NSA absolutely love. They (and their governmental contractors) love knowing everything you do online and on your phone. They track just about everything we do online.

But with encryption, we can keep our text messages, emails, and other personal information safe from the government, schools, and even your family. Encryption is how you keep secrets secret.

If you’re also interested in encryption and cryptography, here’s a free course from Khan Academy that teaches you the basics of how cryptography works.
