Step-by-Step Saprouter Certificate Renewal

1. You need to remove the old generated files(certreq, cred_v2, local.pse, srcert) from previous

certificate request. To do this you can either rename these files or create a new folder and move

these files into it.

2. Login to http://service.sap.com/saprouter-sncadd and click the “Apply now” button. From the list of

SAProuters registered to your installation, choose the relevant “Distinguished Name”.

3. Generate the certificate Request. To do this go to your SAProuter server and run this command on

the saprouter directory.

sapgenpse get_pse -v -r certreq -p local.pse “<Distinguished Name>”

Example:  sapgenpse get_pse -v -r certreq -p local.pse “CN=example, OU=0000123456,

OU=SAProuter, O=SAP, C=DE”

You will be asked twice for a PIN here. Please choose a PIN and document it, you have to enter it

identically both times. Then you will have to enter the same PIN every time you want to use this PSE.

4. Display the output file “certreq” and with copy&paste (including the BEGIN and END statement)

insert the certificate request into the text area of the same form on the SAP Service Marketplace

from which you copied the Distinguished Name.

5. In response you will receive the certificate signed by the CA in the Service Marketplace.

Copy&paste the text to a new local file named “srcert”, which must be created in the same directory

as the sapgenpse executable.

6. With this in turn you can install the certificate in your saprouter by calling: sapgenpse

import_own_cert -c srcert -p local.pse

7. Now you will have to create the credentials for the SAProuter with the same program (if you omit -

O <user_for_saprouter>, the credentials are created for the logged in user account).

sapgenpse seclogin -p local.pse -O <user_for _saprouter>

Note: The account of the service user should always be entered in full <domainname><username>

8. This will create a file called “cred_v2″ in the same directory as “local.pse”

9. To check if the certificate has been imported successfully, run the following command: sapgenpse

get_my_name -v -n Issuer

The name of the Issuer should be: CN=SAProuter CA, OU=SAProuter, O=SAP, C=DE
