“Off-the-Record Messaging, commonly referred to as OTR, is a cryptographic protocol that provides strong encryption for instant messaging conversations. OTR uses a combination of the AES symmetric-key algorithm, the Diffie–Hellman key exchange, and the SHA-1 hash function. In addition to authentication and encryption, OTR provides perfect forward secrecy and malleable encryption.

The primary motivation behind the protocol was providing deniability for the conversation participants while keeping conversations confidential, like a private conversation in real life, or off the record in journalism sourcing.”

Note that Pidgin stores your IM account passwords in plain text. You can avoid this by (1) not saving your password in Pidgin, (2) encrypting your file system, or (3) storing your Pidgin password securely with the Debian package pidgin-gnome-keyring.

Pidgin with OTR and dbus enabled has a local security bug. See the upstream bug report for more information and possible workarounds.

What is an MTA?

“Within Internet message handling services (MHS), a message transfer agent or mail transfer agent (MTA) or mail relay is software that transfers electronic mail messages from one computer to another using a client–server application architecture. An MTA implements both the client (sending) and server (receiving) portions of the Simple Mail Transfer Protocol.

The terms mail server, mail exchanger, and MX host may also refer to a computer performing the MTA function. The Domain Name System (DNS) associates a mail server to a domain with mail exchanger (MX) resource records containing the domain name of a host providing MTA services.”

Try to use Tor Browser as often as possible. Browsing is slower with Tor, but far more secure.
