Just follow these steps:
A Certificate Signing Request (CSR) is a coded text block forwarded to a Certificate Authority (CA) during the SSL Certificate application process. Typically generated on the server where the certificate is to be installed, the CSR includes pertinent details for incorporation into the certificate, such as the organization name, common name (domain name), locality, and country. While the PKCS #10 specification is the most prevalent format for CSRs, various other formats are also compatible.
The CSR, crafted in the PEM format, encompasses the public key section of the private key and details about the entity (individual or company). Included in the CSR are the two-letter country code, state/province, and city where the company is legally situated.
After generating the CSR, the next step involves submitting it to the CA alongside payment for the SSL Certificate. The CA then processes the request, issuing a digital certificate in return. This certificate file holds the public key of the website and its identity, along with related information. Installation of the digital certificate on the website is imperative to activate HTTPS.
The extension CRT is employed for certificates, with CER and CRT being almost interchangeable. This is especially prevalent in *nix systems. A file with a .crt extension encompasses an end-entity certificate, its public key, and identity details such as domain names verified to be linked with the certificate.
CRT certificates play a crucial role in enabling secure TLS handshakes, substantiating website identity ownership to browsers, and establishing encrypted sessions that are shielded against eavesdropping and content tampering.
