Revoking certificates
Do you suspect that your certificate data is being misused, or have you lost your signature card? These are examples of cases in which you should have your certificates revoked immediately. There are several ways you can do this.
Information on the revocation of certificates
D-Trust issues a wide range of certificates. Each product offers different options for revocation if needed.
If you don’t find the answer to your question here, our colleagues from the call and support centre are also available by telephone: +49 (0) 30 25 98 - 0 (business days from 7:00 a.m. to 6:00 p.m.).
In the case of signature cards, the person applying for the card is always the person authorised to revoke the card, as are any other persons with specific authorisation to revoke.
How to have your personal signature card revoked
Depending on the card, you have the following options to initiate its revocation:
- Online in the D-Trust Portal for signature and seal cards:
https://portal.d-trust.net
To revoke a card, you must first log in to your existing account, where you will find your valid cards in the product overview. The revocation function is directly accessible from there. Please note that this option is only available for cards that have been applied for via the D-Trust Portal.
- Online via the D-Trust service page:
https://my.d-trust.net/sperren
Cards that were not applied for via the D-Trust Portal can be revoked via our service page. You will need your application ID or card ID. In this case, you have assigned a revocation password for your card yourself when ordering or you have stored a mobile phone number for the SMS-TAN procedure.
- Written requests for revocation are possible. In this case, the letter to D-Trust must be signed personally and contain the application number of the signature card. Please address your letter to:
D-Trust GmbH
Sperrdienst (Revocation Services)
Kommandantenstrasse 15
10969 Berlin.
Important information on the revocation of your signature card
The revocation of a signature card cannot be reversed and affects not only the signature certificate, but also the authentication and encryption certificate of your card. Please remember that you will need this card and its associated keys and PINs to be able to decrypt any data that was encrypted using your card. Since you will still need the card for data decryption, you should store it in a secure location.
You’re authorised to revoke a signature card and you want to revoke it?
A list of persons authorised to revoke can be stored with D-Trust at the time of application. When an organisation or an occupational attribute confirmed by an organisation is entered in a certificate, it is mandatory to store a list of persons authorised to revoke.
As a person authorised to revoke, you have the following options to initiate revocation depending on the card:
- Online via the D-Trust service page:
https://my.d-trust.net/sperren
You have received a letter from D-Trust GmbH with a revocation password for a card. It will allow you to revoke this card via our service page. You will need the application ID or card ID and the revocation password from the letter.
- Written requests for revocation are possible. In this case, the letter to D-Trust must be signed personally by the person authorised to revoke and include the application number of the signature card. Please address your letter to:
D-Trust GmbH

If you are a user of sign-me remote signature, log in to your sign-me account. Go to “Settings” and then “Manage signature certificates”. Here you must select the certificate that is to be revoked. In the certificate’s display, you find the button “Revoke”.
If you are a user of the seal-me remote seal service, you can revoke the seal certificate via the API connection used. Alternatively, you can arrange the revocation of the seal ID used for the remote seal service. The procedure is described in the “Revoking Certificates from the Certificate Service Manager (CSM)” section.
All certificates created via the Certificate Service Manager (CSM) can also be revoked directly via the CSM.
If you do not have access to the CSM, please contact your operator to have the certificate revoked on your behalf.
