About CSR Decoder

The CSR Decoder tool helps you decode and view the details of a Certificate Signing Request (CSR) file instantly. When you generate a CSR for SSL certificate installation, the data inside is encoded and not human-readable. This tool lets you easily view all the important information within that CSR file in a readable format.

Whether you’re an IT professional, developer, or website owner, the CSR Decoder simplifies the process of verifying CSR content before submitting it to a Certificate Authority (CA).

What Is a CSR (Certificate Signing Request)?

A Certificate Signing Request (CSR) is a block of encoded text containing essential information about your website or organization, including your public key. It’s submitted to a Certificate Authority to request an SSL certificate.

The CSR file usually looks like this:

-----BEGIN CERTIFICATE REQUEST-----
MIICzDCCAbQCAQAwgYExCzAJBgNVBAYTAklOMQ8wDQYDVQQIDAZHdWphcmF0MQ8w
...
-----END CERTIFICATE REQUEST-----

The CSR Decoder allows you to decode this text and view its real contents such as the Common Name, Organization, Country, and Public Key details.
