• Always keep the private key secret.
When you want to
communicate with someone you share your public key. Messages
are encrypted with the public key of the recipient by the sender and
decrypted by the recipient with their private key when the message
arrives. 221
• GPG4Win is an example of software that performs with PKE. 222
• It is also recommended to use privacy-focused email hosts such as
Mozilla Thunderbird or RiseUp.net to protect personal
information.223
Regarding online activity, consider the following issues:
• For anonymity, use anonymous surfing modes to prevent your
browser from saving your information automatically. However, be
aware that using these anonymity modes will not make you
completely anonymous.
• Alternatively, use the software TOR as an accessible, free, and
easy means to protect your privacy and anonymity. The main
component of the software is the Tor web browser. This hardened
and secured-focused version of Firefox encrypts your online
activity and bounces it through computers around the world,
making it more difficult to trace.
• In addition, for confidentiality, to ensure that outsiders do not
gather information about you when browsing online, use a virtual
private network (VPN) to appear to be someone else, in a different
place. A VPN secures the traffic between your computer and
servers, and masks your IP address and location. Several VPNs are
available, ranging from the free and simple HotspotShield to highend subscription services like SurfEasy Total.
• Use a program like CCleaner to regularly remove all the
information, passwords, files, and downloads that your web
browser saves.
As with securing electronic documents, the online platform Security
in-a-box has developed a guide on safe and private online communication.
