This input dialog is the central part for collecting all data regarding certificates, requests and templates. It will be invoked whenever such an item is going to be created or, in case of a template, is altered.
This page is not shown when creating or changing templates.
If it is desired to either enroll a certificate from a PKCS#10 request by a local CA, or to create a certificate from a request by self-signing it, the request can be selected here. In the later case the private key of the request must be available.
Either self-signing or the CA certificate for signing may be selected here. Additionally, the desired signing algorithm can be adjusted. The drop-down list contains all CA certificates with an available private key.
Usually SHA256 or higher should be used, but since older windows versions including XP can not handle them, you may opt to use SHA1. The default signing algorithm may be selected by the Options menu.
The fields of the certificate can be preset by the values of a template by selecting it and clicking Apply all. Templates can be mixed by applying the subject of one template and then applying the extensions of an other by using the buttons Apply subject and Apply extensions
On this Page all personal data like country, name and email address
can be filled in.
Country code field must either be empty or exactly contain
two letters representing your country code; e.g.
DE for Germany.
If you want to create an SSL-server certificate the
must contain the
DNS name of the server. Alternatively the subject-alternative-name
extension may be used to define additional DNS names, even wildcards. In this case
the CommonName must be repeated here, because Web servers disregard the CommonName
in case ithe subject-alternative-name extension exists.
internal name is empty, the common name will be used
as internal name.
It will also be used as default internal name, if a new key is created here.
Other rarely used
name-entries can be selected in the dialog below.
By using this table instead of the table above, the order of the entries can be adjusted.
A new line can be added via the Add button.
The current line can be deleted via the Delete button.
Existing lines can be exchanged and reordered by moving the row-header (containing the row-number) around.
All items can be added more than once, even those from above. This is not very usual but allowed.
The list of the 7 explicit distinguished name entries may be adjusted in the options dialog at Explicit subject entries
Keys can be generated here "on the fly" by pressing the button.
The name of the new key will be preset by the common name of the certificate.
The newly generated key will be stored in the database and stay there,
even if the input dialog is canceled. The drop-down list of the keys
only contains keys that were not used by any other certificate or
request. The key-list is not available for creating or changing templates.
Used keys too the list contains all available
keys. Use this with care. You're likely doing something wrong when using this
This tab does not appear when signing a request, because the request contains all needed data from this tab. Select "Modify subject of the request", if you want to modify it anyway. The content of the subject Tab will then be preset with the content of the request.
The next three tabs contain all fields for adjusting the certificate extensions.
It is not in the focus of this document to explain them all in detail.
The most important are the
Basic Constraints and the
For more information consult the documents in otherdoc . If you don't know what this is all about please read those documents before creating any certificates.

instances as issuer for other certificates.

not Before field is set to the current date and time of the
operating system and the
not After field is set to the current
date and time plus the specified time range.
When applying time ranges, the expiry date (not after) is calculated by taking
the currently configured start date (not before) and adding the time range.
For templates the specified times are not saved, because it does not make much sense.
Rather the time range is stored and automatically applied when selecting this
template. Applying the time range means to set notBefore to "now" and notAfter
to "now + time range". If the
midnight button is set both dates will be
rounded down and up to midnight.
Any extension, not covered on the other tabs can be added here as
defined in OpenSSL nconf. The validity can be checked by clicking
Validate. All extensions from all tabs will be shown here
to see them all in their final form. Click on
Edit to continue
editing the extensions here.
Refer to the OpenSSL X509v3 configuration for more details: http://www.openssl.org/docs/apps/x509v3_config.html
The following example of
openssl.txt also works in the advanced tab
to define certificate policies
certificatePolicies=ia5org,184.108.40.206,220.127.116.11.8,@polsect [polsect] policyIdentifier = 18.104.22.168 CPS.1="http://my.host.name/" CPS.2="http://my.your.name/" userNotice.1=@notice [notice] explicitText="Explicit Text Here" organization="Organisation Name" noticeNumbers=1,2,3,4
Adding more than one AuthorityInfoAccess entry is also possible here:
authorityInfoAccess=@aia_sect [aia_sect] OCSP;URI.1=http://www.some.responder.org/ OCSP;URI.2=http://www.some.other-responder.org/ caIssuers;URI.3=http://server.whatever.org/cert-path caIssuers;URI.4=ldap://server.whatever.org/xxx,yyy
When exporting existing Certificates to templates, the extensions will be translated to OpenSSL config file format.
