PGP fixes this by encrypting your emails, guaranteeing solely the meant recipient can decrypt and browse them.

Snowden’s 2013 leaks uncovered how companies just like the NSA gather huge quantities of information on everybody—not simply criminals—by tapping into tech giants like Google and Fb. PRISM and different applications made it clear that nobody’s knowledge was protected from authorities eyes.
Julian Assange’s work with WikiLeaks additional highlighted how governments use non-public info in opposition to residents with out their information, sparking world considerations over privateness rights. The concept that “when you’ve got nothing to cover, you don’t have anything to concern” is flawed. As Snowden famously mentioned, “Saying you don’t care about privateness as a result of you don’t have anything to cover is like saying you don’t care about free speech as a result of you don’t have anything to say.”

Right here’s the way it works in easy phrases:
- Public and Personal Keys: Once you arrange PGP, you generate a pair of keys—a public key and a private key. These two keys are mathematically linked, however whereas the general public key could be shared with anybody, the non-public key’s stored secret and recognized solely to you.

Once you ship a message, PGP creates a singular signature utilizing your non-public key. The recipient can then test this signature in opposition to your public key to confirm that the message is de facto from you and hasn’t been altered in transit.
A Actual-World Instance of PGP Use
Think about you’re a journalist masking a controversial matter (or any matter that’s not authorities “accepted”), and also you’re speaking with a confidential supply. You don’t need your emails intercepted by hackers or authorities companies. By utilizing PGP, you may ship encrypted emails to your supply, guaranteeing that solely they’ll learn your messages. Moreover, your supply can use PGP to ship encrypted replies, retaining either side of the dialog non-public.
That is exactly the form of privateness safety that whistleblowers like Edward Snowden have relied on to reveal authorities wrongdoing with out concern of speedy detection.
