Product details

Encrypt and sign e-mails

Personal certificates can be used to encrypt and sign e-mails. These are important measures if you want to protect yourself against hacker attacks or to unambiguously authenticate yourself to the recipient of an e-mail as the sender.

Access company networks

Companies must ensure secure employee authentication. Only authorized employees should be able to access specific data stored on the server, in the IT system or in the network. Employees can use their personal certificates to identify themselves to the systems. If the certificate fits, the employee will then have secure access to the systems and data. In order to enhance security even further, the certificate can also serve as the basis for two-factor authentication.

Sign or seal documents

More and more companies in Germany are using electronic signatures in order to accelerate their signature and validation processes and to move away from paper-based processes. With our personal certificates, advanced electronic signatures can be be attached to documents. This ensures the authenticity and integrity of the document and that a later modification does not go unnoticed.

If digital documents are to be sent by an organization, this is where the electronic seal comes into play. In technical terms, electronic signatures and the electronic seal are almost identical. Unlike the electronic signature, the seal is not assigned to a natural person, but to a legal entity, such as a company or an authority. What’s more, the purpose of a seal should not be confused with a declaration of intent, instead it confirms both the origin and ‘originality’ of the electronic document. 

With its Qualified Seal ID product, D-Trust offers an advanced seal which, in contrast to the qualified seal card, ensures a qualified identification level and thus the use of a qualified certificate, but which was not created by a qualified seal creation unit. It is therefore used where hardware-based certificate holders cannot be used or do not have sufficient performance or where a qualified signature is simply not required. The seals are always supplied in the form of a soft certificate for use in server environments or in systems not operated by end users.

Certificates for specific sectors

Secure data exchange between persons subject to a legal obligation of professional secrecy

As a specialist in secure identities, D‑Trust also supplies personal certificates that are accredited according to technical guideline TR‑03145 of the Federal Office for Information Security (BSI). A solution designed for companies, public authorities and institutions with security level (VS-NfD – RESTRICTED).

Special rule for the energy, water, electricity and gas sectors

Our certificates are also suitable for use on e-mail gateways or as a gateway ID. With an e-mail gateway, all e-mails that pass through your server are automatically signed with an advanced electronic signature and encrypted.

Special rule for the energy, water, electricity and gas sectors: Since 1 January 2019, all personal certificates in these industries must be signed using RSASSA-PSS according to a guideline issued by the Federal Office for Information Security (BSI). RSASSA-PSS is an improved signature scheme that includes an appendix. An RSA key is used to sign the data and the recipient uses a public key to verify the signature. ‘PSS’ stands for ‘Probabilistic Signature Scheme’. Certificates issued by D-TRUST meet the requirements regarding RSASSA-PSS.
