What we're going to cover:

• Encrypted phone calls
• Encrypted text messaging
• Encrypted instant messaging
• Safer web browsing
• A look at future applications
• Useful resources and further reading

General considerations

• Encryption-by-default where possible lowers the risk of your privacy in general from being invaded.
• There is no such thing as perfect security.
• Understand your threat model.

Encrypted phone calls!

Encrypted text messaging!

Android: TextSecure

iOS: nothing trustworthy yet :(

Open Whisper Systems are working on porting TextSecure to iOS as part of Signal, so keep your eyes peeled.

Safer web browsing!

Simple suggestions

• Use HTTPS where possible.
• Use ad-blocking plugins for your browser (eg Adblock Plus).
• Use tracker blocking plugins (eg Disconnect.me or Ghostery).
• Use VPNs and Tor depending on your threat model and goal.

Plugin: HTTPS Everywhere

• Attempts to do what it says on the label.
• Will automatically push your browser to the HTTPS URL when a website supports HTTPS.
• Installation/usage: https://www.eff.org/https-everywhere

Tor: what does it do?

• Tunnels your browsing through several other nodes.
• Makes it harder for someone to monitor your activities.
• Censorship-resistance due to how the protocol works.

Tor: how does it work?

Tor: what doesn't it do?

• Does not guarantee anonymity.
• Does not protect you from unencrypted communication tampering at end nodes.
• Does not do operational security for you.
