To put this in perspective, only video chat is more popular at 57%.
Pidgin already has plugin support for encrypted messages. However, it helps if all your buddies have it installed too.
Thus, I asked the developers what they thought of installing encryption by default. Here's what we agreed on:
- OTR (Off The Record): OTR is the most secure encryption protocol available for Pidgin, and is already a default for Adium users. While promising, it has some usability bugs that need work. Ian Goldberg, the professor who created OTR, told me he would love to have people contribute patches.
- Pidgin Encryption: Pidgin Encryption has no private method of key exchange and verification, which can create a false sense of security.
- Pidgin Paranoia: Pidgin Paranoia uses a form of encryption that is strong on paper, but in practice is vulnerable to attacks.
- XMPP/PGP: XMPP/PGP isn't as secure as OTR, but is a published protocol standard. The developers will welcome a well written patch for this.
Long story short, we won't be including encryption in Pidgin despite how popular it is. Sorry. This may be reconsidered when improvements have been to the plugins.
I hope this gives some good insight into decisions that are being made. Feel free to ask if you want more clarification on what I wrote here.
