Allows the sending of fully encrypted emails via the Mac Mail app and Thunderbird
GPGTools is an open source initiative to bring OpenPGP to Apple OS X. This allows you to sign, verify, encrypt and decrypt files and e-mails. The project is originated from efforts revamping GPGMail developments in 2010.
The personal privacy is one of the most underestimated goods everyone of us has. By encrypting your data before sending them over the internet you prevent others from reading them during the delivery process. Where the "others" can not only be negligible hackers but more important criminal individuals, business companies or even governments interested in your personal information for various reasons some of them you can't even imagine!
Another point is the origin of information. Every piece of information has its source that inseparably belongs to it. The source of an information is almost as importand as the information itself. By using GPGTools the reciever of an email or file can be sure the information has been sent by only you. He even can tell if the content has been altered on its way through the internet and is therefore not valid for you. PGP messages cannot be faked! - Not partially, not completely, NOT AT ALL!
