Mycelium is the maintainer of the portuguese translation of Email Self-Defense - a guide to fighting surveillance with GnuPG encryption, developed by Free Software Foundation. The guide was translated in a collaboration between CMI-Rio and Thiago Marinello.
Bulk surveillance violates our fundamental rights and makes free speech risky. This guide will teach you a basic surveillance self-defense skill: email encryption. Once you've finished, you'll be able to send and receive emails that are coded to make sure a surveillance agent or thief intercepting your email can't read it. All you need is a computer with an Internet connection, an email account, and about half an hour.
