Key Details to Check and Validate
Pasting your CSR into our checker allows you to meticulously review all the critical data. Pay close attention to the following fields:

Organization Details: Validate that the legal name of your Organization (O) and the specified Organizational Unit (OU) are exactly as they should be.
Geographic Accuracy: Confirm that the City (e.g., Colombo), State (e.g., Western Province), and Country (LK) match your official business location.
Public Key Strength: Check that the cryptographic key strength (e.g., 2048-bit RSA) meets the current security standards required by your CA.
