As well as providing certainty about the identity of the owner, certificates offer the possibility of encryption. Encryption and integrity are key prerequisites for secure internet communication. There are many ways to encrypt and secure files. However, in practice, the public and private key method has proved the most reliable. This method uses two keys, a public and a private key. The sender encrypts the messages using the recipient’s public key. To render the message legible again, the recipient decrypts it using his private key. This happens automatically for communication with GTS. Put simply, a certificate ensures that through a combination of a user name and a password, you can log in on secure parts of the GTS website.
Both a personal and a system certificate are valid for one year. You can check the validity period of your certificate in the following ways:
Internet Explorer: click on Extra > Internet options > Content > Certificates.
Firefox: click on Preferences > Advanced > Encryption > View certificates. On both internet browsers you can see all the installed certificates followed by the date on which the period of validity ends.
You have received an email notification that your certificate is about to expire. You can renew it by following the link and completing all the fields required.
The computer on which the certificates are to be used must meet the following minimum requirements:
- A Windows version that is supported by Microsoft and of which the most recent updates, and service packs have been installed;
- Internet Explorer 8.0 with 128-bit encryption or a later version;
- An internet connection.
GTS has compiled a guide on how to make a back-up. You will find it here. We recommend that you store the back-up on a removable docking station or personal network folder. Then if something should happen to your computer, you can replace the certificate from the removable station and carry on working without problems.
Yes, you can do this using a back-up. However, this is only permitted if the user of the certificate also remains the user on the new computer.
You can request extra certificates for new users via the application form which you find in the section Downloads and Forms.The application must be authorised by the GTS-registered contact.
If your certificate has disappeared, e.g. due to a hard disk malfunction or deletion error, you can replace it using the back-up you have made. A description of how to replace a back-up is included in the back-up certificate handbook. This document can be found under the section how to make a backup of your certificate.
You cannot however retrieve and reinstall your certificate a second time! If you have not made a back-up, you can revoke your certificate and enrol it again. Should that give any problems please contact the certificate manager: firstname.lastname@example.org
Your certificate might no longer be valid. Or you may not have log-in rights. Contact email@example.com
Your e-mail address may have changed from the one you originally used to apply for the certificate. If the old address is no longer valid, it will not be possible to send you a notification for renewal. Please contact: firstname.lastname@example.org
You can check to see if your certificate needs renewing by opening Internet Explorer on your computer and then clicking in the menu bar on Tools > Internet Options > Content > Certificates. This will call up a screen showing all the certificates that have been installed on your computer. Behind each certificate is the date up to which the certificate is valid (Expiry date). If this date is less than a month in the future, you can renew your certificate. If this date is more than a month away, you will not yet be able to renew your certificate. If the date lies in the past, the certificate has already expired.
If you have forgotten your passcode, you can apply for the code via email@example.com
