Frequently asked questions

: A CSR stands for Certificate Signing Request. It is a block of encoded text containing information about the entity requesting a certificate from a Certificate Authority (CA). The CSR includes the organisation's name, common name (domain name), locality, and country. It also contains the public key that will be included in the certificate.
When you apply for an SSL/TLS certificate from a CA, you generate a CSR on your server. The CA then uses the CSR to create your digital certificate, which encrypts communications between clients and your server over the internet. The process ensures that the public key can be trusted by users and devices communicating with the server, and the CA has verified it as a trusted third party.
