Re: [Linphone-users] Any plan for OTR chat?

[Johan Pascal]

Hi Anthony,

LIME is partially based on SCIMP, the encryption mechanism created by Zimmerman(ZRTP author) for Silent Phone. I just updated linphone dokuwiki to add a description of it:

https://linphone.org/dokuwiki/doku.php/liblinphone:lime

Hope it will answer your questions. It's missing the part describing file transfer encryption, I'll add it soon.

As far as I know there were no public review of LIME, sorry.

Regards,

johan

Hi,

there is no plan to implement OTR, but for linphone to linphone
chat, you can activate LIME to encrypt your chat and file transfer
using secrets previously generated using ZRTP: for it to work you
must first make a voice call to the peer, then you can chat in a
secure way.

Hi Johan,

Thanks for the prompt answer. I have a few other questions if you
would indulge me for a few more moments:

1. Since LIME is not a standard and something the project has created,
does that mean you've created your own encryption algorithm? I
understand it's based on zRTP but how does the protocol differ from zRTP?

2. Is there anywhere I can read how the protocol works besides
browsing the source?

3. Has there been any peer review around LIME and, if so, is it
available for public view?

Thanks for your time. So far, I'm LOVING Linphone! Sorry to be a pain
in the behind but I'm trying to understand a few things so I can use
the program most effectively.

Thanks,
Anthony
