After receiving certificate you should install it as described below.

In production environment

Moscow exchange is a certificate authority which issues certificates for clients, and those certificates are then used in several systems including NSD EDI.

In production environment the whole process of obtaining certificate is much more strict, since absolute security must be provided and all sides must be sure, that their keys are not compromised. The same or almost the same process of receiving certificates are used by all well known certificate authorities like Comodo, Thawte and others.

To obtain a production certificate client should do the following steps:

1. Enter an the electronic data interchange participation agreement.
2. Fill an Application for Production of the Electronic Signature Verification Key Certificate.
3. Receive a registration certificate from Moex. Under 'receive' we assume physical delivery in Moex office in Moscow on CD to the person itself or his representative with power of attorney.
4. Install corresponding software on his computer.
5. Generate a pair of public and private keys.
6. Create a request to issue certificate for that pair of keys. Sign the request with the registration certificate and send in to MOEX (pki@moex.com).
7. Receive a production certificate.

Installing certificate

Before taking any actions with certificates, client should install corresponding software, as described here.

Production or test certificate

After installing the Certificates storage you can run it by clicking the corresponding menu item in Windows programs list as shown below.

Fixing locale issue

Since the program doesn't have English interface, on operating systems with English locale you'll see broken interface with question signs instead of readable text.

To fix this issue first of all we have to close the program by clicking Cancel button on the dialog which you see on the image above, then No on the next dialog,  then Ok, then No and then Ok, Program will be closed.

Then we need to change system language for non-unicode programs. To do that we go to the Control panel and there select Clock, Language and Region section. In this section click on Change location link. On the shown form go to the Administrative tab and press Change system locale button. Select Russian. System will ask to reboot, do that. Set of screenshots below illustrates the described process.

Now run Certificates storage again, it's interface now doesn't have question signs.

Saving certificate to disk

Certificate authority sends certificate as a zip archive. Unpack it to any separate folder. There will be a folder named Spr, one file with *.cer extension and one with *.rsa extension. 

Installing certificate

After running Certificates storage shows a dialog which makes user to select a folder. Press Cancel there and then Ok on the next error dialog.

With next dialog program asks user whether he has a copy of certificate to restore. Press Yes.

 and on the next dialog select the Spr folder from the folder, in which we've unpacked the archive. Press Ok on the next dialog, the program will be closed.

Run program again. If previous actions succeed, we'll see the following dialog:

Press Ok.
