A digital certificate ensures the identity of the holder. A so-called SSL/TLS certificate testifies to the authenticity of your web presence through the reliable verification of your domain and other company information and ensures that operating systems and browsers also trust you. Simply put: A digital certificate is used where the source of information must be clearly verified.

> Website encryption (secure connection between browser and server via HTTPS)
> E-mail encryption and signature
> Signing of digital documents
> In all other systems that require secure digital communication

Digital certificates are relevant for security reasons on the one hand, as they ensure a secure connection between two communication sources, and for trust reasons on the other. This is because encryption generates trust in digital use. As a company, you thus create trust with your customers.

In the case of digital certificates, a distinction is usually made between SSL/TLS and e-mail certificates.
A trustworthy SSL/TLS certificate attests to the authenticity of your web presence through the reliable verification of your domain as well as other company information and ensures that operating systems and browsers also trust you.
Using the e-mail certificates, e-mail communication, for example with customers and business partners can be trustworthily signed and encrypted with all common e-mail programmes and mail gateways.

The use of digital certificates is highly relevant for all companies that want to transmit information securely and encrypted in the online world. The basis of this encryption is an asymmetric cryptographic procedure with private and public keys. Private individuals also use digital certificates, for example e-mail certificates, to guarantee the authenticity and integrity of a message.

To determine the trustworthiness of a website, the address line of the browser should be checked. On the one hand, the lock symbol indicates a secure connection and on the other hand, the address begins with https:// (not https://). In addition, the validity of a certificate can be displayed by clicking on the lock symbol.

An e-mail signature, or so-called S/MIME signature, is displayed differently in each e-mail client. However, the public certificate is always visible and can be recognised by different icons, depending on you e-mail client.
E-mail encryption, or S/MIME encryption, can only be decrypted with the recipient's certificate and key.
