Organisation Assurance

However, since the new documentation is finished you might find some useful information here. But be aware: A lot of things have changed. Maybe you would also like to have a look at the Organization Assurance Manual.

Email & Server Certificates for Organisations

Important note

If you have knowledge in law and you want to help CAcert org Support, please see HelpingCAcert


Having your organisation assured allows you to issue certificates in the name of your organisation, have additional information added to certificates, and issuing certificate for any arbitrary email address in your domain without the need to go through verification every time. You can also delegate (and revoke) the authority to other administrators within your organisation.

Organisation feature benefits

  1. The CAcert Organisational feature is pretty interesting because you can include more details than the simple CAcert user (organisation name, localisation). After the organisation account is created, you have the same easy way to generate email or webserver certificates.

  2. Also, because you're responsible of your organisation, you can generate user certs for any of your employees (including the organisation name) without going thru the whole assurance process (TTP or CAP). Here, CAcert delegates its responsabilities to the owner/executive manager of the organisation.

  3. Because we do not provide any sub-root certificate, we assure the whole CAcert community that the root certificate trust is less likely to be compromised (see SubRoot).

How to request the organisation features ?

CAcert has a general policy for Organisation Assurance. When an Organisation Assurer is available in a country, a specific policy has been written to handle Organisation requests for the country.

Mainly, the following countries have several organisation assurers:

For all other countries, please ask first support (at) to know if we can handle a request (and see the table below).

The "organisation Assurers" are similar to the way the Web of Trust assurers are doing their "job". Local Assurers permit to overcome the problem of reading/knowing the local languages & organisation legislations. Also, it's easier to verify the will of the owner/executive manager in case, he/she is not fond of IT and doesn't have a proper & trusted digital certificate & signature.

Also, if you need specific help or questions, you are welcome at IRC channel #cacert if you are kind enough we will try to speed-up the procedure.

Additional steps

  1. The person responsible for the organisation needs to appoint 1+ admin(s) in charge of generating/taking care of the certs for the organisation. The admin must have a certain amount of trust and knowledge, so they need to be a current CAcert assurer. The admin can be or not a member/employee of the organisation, so you can ask your usual IT service provider to do the job.

  2. From the certificate of incorporation, the CAcert support (or Organisation Assurer) can get info about the organisation and add them into the organisation account : its name, its place of incorporation (Town, state, country), then add the owner/executive manager email address for contact, add the admin list (for each admin, the department name in the organisation if applicable), add the list of the domain names of the organisation after a check of one (or more) authoritative email address(es) (like postmaster@domainname).
  3. The domain names that can be included in the account have to match the certificate of incorporation info when looking at the whois database or any accurate document linking the organisation and the domain name.

For precise requirements for different jurisdictions please contact support(at) who will gladly put you in contact with an organisation assurer!

Corporate use of organisational client certificates


When I create a org client certificate, how does the user pick up the new certificate that is created?


The "corporate" use of org client certificates is to put them on a smartcard. So after, you just give each user its usb smartcard with its PIN code and the certificate/private key loaded.

You'll probably need to configure the mail client on the user machine. Also, there is still an "underground" project to generate certs for windows domains.

In this case, if you want to know which smartcard is easy to integrate, we can help you, so just ask support (at) Some people at CAcert support have tested several cards.

For example, there is a special type of card "java smartcard" but it's pretty complicated to use. Anyway, people at CAcert support frequently log-in CAcert website and we're really happy to use smartcards to quickly log-in, as the server safely gets the our id from the card.

Note : the CAcert interface permits to generate the private key directly within the card and properly load the certs after signing.

If you have no smartcard, as a last resort, you can put the client cert from your browser certificate store into a pkcs12 file and transfer it in on a usb memory key and give it to the user but it's not really seamless ;(


(to read if you have extra time to spend)

Only the designers of the org support can tell but here's my guess :
the idea is to have an admin for one department (one for IT, one for HR,
2 options :
- deleting an admin and putting no Departement or giving the department field (OU) a more "general" sense instead of IT/Support.
- delegating cert creation to other "local" admins (only 50 points are needed for an admin AFAIR)
you can only generate certs for the domain(s) that is(are) registered for the org

FAQ - Frequently Asked Questions

Q: The technical representative in our company has been changed, and the old one used his personal CAcert account to issue our mission critical certificates. How could we change the login credentials to this site?

A: First, create a new account for yourself if not set up yet. Then do the following steps: 1) Login to the account 2) go to "Dispute" -> "Domain" 3) enter the Domain 4) choose an email address you can reach, and dispute the domain. 5) You’ll get an email you have to approve, then the Domain should be removed from the others account. 6) Afterwards you can add the domain to your own account, and issue a new certificate for it.

After all you should think about doing OrganisationAssurance, so that several people in your company can issue certificates, and it can continue without problems in case you leave the company too.
