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 DER format, an acronym for Distinguished Encoding Rules, represents a binary variation of PEM-formatted certificates and finds prevalent usage in Java-based platforms. Primarily deployed in applications prioritizing security, such as e-commerce and online banking, DER certificates are also favored in certain mobile applications and embedded systems.
Several advantages accompany the use of DER certificates. Firstly, their heightened security is attributed to the binary format, making tampering exceedingly challenging. Secondly, their efficiency stems from the swift processing enabled by the binary structure. Thirdly, the portability of DER certificates is notable, facilitating seamless transfer between different systems.
Despite these advantages, DER certificates come with some drawbacks. Firstly, they can be challenging to read due to the binary format, impeding easy inspection of certificate contents. Secondly, editing DER certificates proves difficult as the binary structure hinders straightforward modifications. Thirdly, managing DER certificates presents challenges in tracking due to the intricacies of the binary format.
DER certificates offer a secure and efficient means of safeguarding data in transit. However, their complexity in terms of readability, editing, and management poses certain challenges.
