You’ve got trust issues. It’s understandable. Recent years haven’t been kind to our naive, blissful worldview that all software developers are looking out for our best interests.

Whether it’s Windows spying on you, or your browser compromising your privacy, there are good reasons to be cautious. Fortunately, there is a way to return to our digital utopian ideals of a safer and more secure internet for everyone: open-source software and tools.

2. OpenSSL

Before 2014, Secure Socket Layers (SSL) and Transport Layer Security (TLS) were mostly unheard of outside of developer and security circles. Then, one of the web’s significant security vulnerabilities was discovered: Heartbleed. It affected an estimated 17 percent of servers running OpenSSL to provide secure connections to websites.

Although Heartbleed was picked up by news outlets spreading panic, the vulnerability was patched the same day it was disclosed. The response time was fast by any measure, made all the more impressive by the size of the OpenSSL team. The development group consists of just 13 people, 10 of whom are volunteers.

OpenSSL was first founded in 1998 as a fork of the now-defunct open-source project SSLeay. From its humble origins, it has gone on to become the standard for web server encryption. Not long after the Heartbleed disclosure, Google forked OpenSSL to create BoringSSL. Although the project is open-source, they explicitly warn people not to use it over OpenSSL, as they forked it specifically for their own use.

To download the file, the recipient does need to open the link in a TOR browser, so this may not be an option for everyone.
