Hi!
 
I've prepared my plugins for the first publication.
 
You can (I hope) get .zip with all files by this link:

It is my working version in which I added and translated comments. Respectively, it is made for Rcube v.1.1.3.
In texts I kept some comments in Russian. Don't pay attention: always nearby there is their translation into English.

I think that this option will allow to understand better work of a plug-in and possibility of its use in other projects.
 
Soon I will begin work with the Rcube 1.2 version.
 
As as I understand, in this version essential changes for encryption of mail are made, I would be very grateful to receive recommendations about application of my algorithms in the new RCube version.
 
The README file contains more detailed comments to a plug-in.
 
Best regards,
   Vladimir Gorpenko,
