In this post, I will talk about configuring an Email server which is accessible using TOR. Using TOR will make its IP to be hidden, also accessible if it is behind NAT (inside a home computer without a public IP). But the main question is why one should use this kind of scenario?

For the email server part, I will use hMailServer, an open source email server developed for windows.Continue reading Configuring a Hidden Email Server
I have a workshop titled “Introduction to Cryptography and PGP” at Urmia University of Technology. I talked about basic concepts of signature and encryption using asymmetric cryptography. Then I talked about PGP which is one of the main usages of this system. I followed the workshop with configuring Thunderbird and GPG4win for applying PGP in Email system. You may find the contents in my previous post about GPG in Thunderbird and the way PGP works.
The pictures of this session is here.
In “Encrypting Emails using PGP/GPG”, I have described how to configure GPG (PGP) + Enigmail + Thunderbird for sending signed and encrypted emails. But the inner process of PGP is not described. In this post, I will describe how PGP works and the emulation process of PGP will be covered by the nice cryptography tool named cryptoolv2.
