Converting CSR to base64 online is easy using Certificatetool.com tool

Just follow these steps:

What is CSR format?

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.

What is Base64 format?

Base64 serves as the established industry standard for encoding SSL certificate content. It is widely adopted across various web servers, which not only generate certificate signing requests but also accept SSL certificates in the Base64 format. This encoding method allows binary data to be represented in ASCII text, ensuring compatibility and ease of transfer between different systems.

The size of the certificate content is a variable factor determined by the encryption strength of the certificate. Higher encryption strength certificates generally result in larger-sized content due to the complexity of the cryptographic keys and associated information. As a result, the Base64-encoded SSL certificates accommodate the diverse encryption requirements of different security protocols, ranging from standard to advanced levels of protection.

Moreover, the use of Base64 encoding is not limited to the SSL certificate itself; it extends to various cryptographic elements, including public and private keys, within the certificate. This uniform encoding approach enhances interoperability and simplifies the integration of SSL certificates across different platforms and services.
