This article explains what a CSR is, why it is necessary, and how it can be easily created.

What is CSR (Certificate Signing Request)?

A CSR (Certificate Signing Request) is a special file created to obtain an SSL certificate. This file, known in Turkish as "Sertifika İmzalama Talebi," is sent to a Certificate Authority (CA) and contains the necessary information required for the issuance of the certificate. The information included in a CSR file consists of the following:

🌐 Domain name (e.g., example.com)

🏢 Organization (company) name

📍 Location information such as city and country

🔑 Public key

⚙️ Signature algorithm

This information is verified by the Certificate Authority. After the verification, an SSL certificate is issued for the domain or organization.

Why Is a CSR Necessary?

A CSR file is absolutely necessary for an SSL certificate to be valid. The CSR is linked to a private key and is uniquely generated for each domain name. Without a CSR, it is not possible to apply for a certificate.

Why Does the CSR Process Seem Difficult?

For users unfamiliar with technical infrastructure, generating a CSR often appears complex. There are several reasons for this:

📚 An overload of technical jargon

🖥️ The need for command-line or terminal knowledge

🚫 Lack of access to the server

❌ Incorrectly generated CSR files can invalidate the application process

At this point, automated tools that work without requiring technical expertise offer great convenience. And this is exactly where GetYourSSL's CSR Generation Tool comes into play.

Easy Solution with the CSR Generation Tool

CSR generation tools make the process accessible to everyone. Especially browser-based tools do not require any additional software installation, and a CSR file can be generated simply by entering basic information.

With these tools:

🧩 Without downloading any programs

❌ Without using the terminal or command line

🎛️ Without dealing with complex settings

⚡CSR and private key can be generated within seconds.

Information Entered During CSR Generation

CSR oluşturma formunda doldurulması gereken başlıca alanlar şunlardır:

🌐 Common Name: The domain name where the SSL certificate will be used (e.g., www.example.com)

🏢 Organization (Organizasyon): The name of the company or organization

🧑‍💼 Organizational Unit (Birim): The relevant department (e.g., IT, Security, Procurement)

📍 Location: City, state/province, and country code information

📧 E-posta adresi: For contact purposes

📏 Anahtar uzunluğu: 2048 or 4096 bits (2048 bits is the current standard)

Once this information is correctly entered, the CSR and private key files are generated.

Security During CSR Generation

Security is the most critical aspect of the CSR generation process.

In browser-based tools, the data generated never leaves the user’s device. The private key is created solely on the user's device and is never transmitted over the internet in any form.

This ensures a method that is both easy and secure, giving users peace of mind while protecting sensitive cryptographic information.

Files Generated During the CSR Process

Once the CSR process is complete, the following files are typically generated:

📄 .csr file: Used to submit the certificate request to the Certificate Authority (CA).

🗝️ .key file: Installed on the server and must be stored securely.

📦 Optional .pem file: In some systems, this may be used as an alternative format.

⚠️ If the private key is lost, a certificate cannot be reissued using the same CSR. Therefore, secure storage of the .key file is critically important.

When Is a CSR Used?

A CSR (Certificate Signing Request) file is required in the following situations:

🆕 When obtaining a new SSL certificate

🔄 When renewing an existing certificate

🔁 When switching to a different certificate provider

🖥️ When migrating to a new server

🧾 During the application process for validation types such as OV (Organization Validation) or EV (Extended Validation)

In all these cases, the CSR acts as a formal request containing encrypted information needed by the Certificate Authority (CA) to issue a valid SSL certificate.

Important Points to Keep in Mind

📝 The CSR file can be opened with a text editor.
It contains base64-encoded data that begins with -----BEGIN CERTIFICATE REQUEST-----

🚫 The private key must never be shared.
It is critical for the security of your certificate and server.

📂 It is recommended to store the CSR and private key in the same directory.
This helps avoid confusion and simplifies the installation process.

✅ Make sure to select the correct files during certificate installation.
Using the wrong file can cause the SSL certificate to fail or be invalid.
