[RCU] S/MIME

Hello!

My smime_crypto plugin is a server-side project.

Storing certificates and keys - a very specific task. So I use separate plugin to manage certificates and keys. Currently it is implemented as a temporary and simplest variant - files. In future it will be a very specific solution, only suitable for my situation.

I use php openssl. I had to add 2 new hooks into rcube_imap class because the existing hooks are not sufficient for this task.

As a variant I am considering the usage of openssl utilits, but not now.

I am ready to give the results of my work to anyone who is interested and to help. But I will not be able to research the structure of Enigma and to build into it my modules.

With best regards, Vladimir Gorpenko
