Five Free apps you use every day and never realise

In no particular order, let’s take a quick look at some free/open source software that you are very likely to use (even if indirectly) every single day, and you don’t even realise exists.

Of course, if you’re a geek (or just have some knowledge of this kind of stuff), you might know about some, or all, of these applications, but still, it’s easy to take some of these gems for granted. So, here’s some recognition for five of those unsung heroes.

1 - OpenSSL

OpenSSL is a free toolkit which powers the encryption in many different applications on the internet. It’s what keeps your credit card details safe when buying online and your passwords are properly secured.

Both servers and browsers, IM applications, or basically anything that uses the internet in a secure manner, probably uses OpenSSL.

That includes Firefox, Opera, Safari, Apache (with mod_ssl to be completely accurate) and many many more!

There are also non-free implementations of the SSL standard, like those found in Internet Explorer (everyone’s favourite love-to-hate browser) and some other server setups too, but among the others, OpenSSL is ubiquitous.

2 - Samba
