Free s/mime certificate from startssl

I wanted for my site to get free ssl to use https. A search on the net brought me here:https://www.startssl.com/. After registration, I got it, but it’s a completely different story … By the way, it turned out that it was very easy to get a s / mime certificate for your mail (no matter which domain).

How to get a free s/mime certificate?

First, in your account, you need to check your email with the Validations Wizard:

a notification will be sent to the email

After that in “Certificates Wizard” you can choose “S/MIME and Authentication Certificate” and get it.

It is saved in the browser automatically, and it needs to be imported for use in mail client.

p.s. to build a chain your mail client may need (for example, I have kmail / kleopatra) StartCom CA Certificates. It’s enough to go to the Toolbox tab and download everything that’s there and then import it into the mail client / certificate manager.

update. In 2016, there were problems with ssl from this company. Perhaps, it is better not to use them. In any case, it’s better to check everything.

Free S/MIME certificate (comodo secure email)

Of course, honest citizens have nothing to hide. However, you will agree that it is unpleasant when personal or confidential information becomes available to someone else. Modern mail clients support wonderful S/MIME. We can take advantage of this function in order not to send mail on the Internet as postcards.

To do this, we will do the following steps:

[1] You can get free s/mime certificate for your email with this url: https://www.comodo.com/home/email-security/free-email-certificate.php

[2] Then carefully fill out the form, come up and remember/write your new recovery password:

[3] Then to the specified email address we receive a message with the subject “Confirm Your Subscription to COMODO Information & Newsletter“. The email confirmation link, which in the letter, needs to be opened in the browser in which you initialized the registration. After confirmation, the certificate must be saved in the repository.

[4] Then in your favorite browser (I have a chromium in the screenshot), you need to extract the received certificate to use it in the mail client:

[5] As you can see in the pictures, in the settings you need select “show additional settings” and find the “certificate management” section, select the certificate from comodo certificate and export it.

Everything, now you can embed in email clients.

p.s. You must export the entire certificate tree, and, possibly, the private key.
