Verify Your SSL Request with the ToolSeel.com CSR Decoder
A Certificate Signing Request (CSR) is the first step towards securing your website. It’s a block of encrypted text that contains all the essential information a Certificate Authority (CA) needs to issue your SSL/TLS certificate. But once generated, a CSR is completely unreadable to the human eye it’s just a long jumble of random characters. Before you submit this crucial piece of code, how can you be 100% certain that all the information within it is correct? A tiny typo in your domain name could lead to a rejected application, wasting valuable time.
The CSR Decoder at ToolSeel.Com is the essential verification tool for every website administrator. It allows you to instantly parse and decode your CSR, translating it back into a clear, human-readable format. Simply paste your entire CSR code including the BEGIN and END tags into our tool, and it will immediately display the details hidden within. At 5:29 PM on August 26, 2025, from our base in Colombo, we provide this vital service to developers and site owners worldwide.
What Information Can You Verify?
Our CSR Decoder extracts and displays all the critical data from your request, allowing you to double-check everything for accuracy before submission.
Common Name (CN): Confirm your domain name (e.g., www.yoursite.lk) is spelled correctly. This is the most common point of error.
Organization Details: Verify the legal name of your Organization (O) and your Organizational Unit (OU) or department.
Geographic Information: Check that the City (L), State (ST), and Country (C) are all accurate.
Public Key Details: See the public key's algorithm and bit-strength (e.g., RSA 2048), ensuring it meets current security standards.
Don't submit your CSR blindly. Gain peace of mind by verifying every detail with the fast, free, and reliable CSR Decoder at ToolSeel.Com. It’s the smart way to prevent SSL issuance problems before they happen.

CSR Decoder FAQs
A CSR Decoder is a utility that translates an encoded CSR (Certificate Signing Request) into a human-readable format. It allows you to check the details embedded within the CSR, such as your domain name and organization, before you submit it to a Certificate Authority.
Simply copy your entire CSR block—including the '-----BEGIN CERTIFICATE REQUEST-----' and '-----END CERTIFICATE REQUEST-----' lines—and paste it into the input box. Click the 'Decode' button, and the tool will instantly display the details contained within your CSR in a clear format.
The main reason is for verification. Decoding a CSR lets you double-check that all the information, especially your domain name (Common Name), is 100% correct before you purchase and issue your SSL certificate. This helps prevent costly mistakes and delays.
No, absolutely not. A CSR file does not contain your private key; it only contains your public key and server details. Your private key should always be kept secret and secure on your server. This tool cannot and will never display your private key.
Yes, your information is secure. The decoding process is performed in real-time for your session only. We do not store or log the CSR data you paste into our tool. Once you close the page, the information is gone, ensuring your details remain private.
