The security of data transmission on the network is one of the key foundations of the modern Internet. Websites, e-commerce stores, electronic banking portals and web applications must absolutely use an encrypted connection using the HTTPS protocol. To implement such encryption, you must purchase and install an SSL/TLS certificate. The first and most important stage of applying for a certificate from a trusted Issuer (Certificate Authority - CA) is to generate a certificate signing request, known as **CSR** (Certificate Signing Request) and the associated private key (Private Key). Our free **online SSL CSR generator** is a safe and professional cryptographic tool. It allows you to generate a CSR code and a strong private key (RSA 2048 or 4096 bits) directly in your browser using secure local algorithms.
Thanks to this, you will efficiently prepare an application for the certification authority, ensure the correctness of the data in the certificate and maintain full security of your cryptographic keys.
CSR code structure and meaning of form fields
The CSR code is a Base64-encoded text file (starting with the line-----BEGIN CERTIFICATE REQUEST-----) that contains your server's public key and detailed information identifying your domain and company. The table below explains the meaning of individual fields that must be completed before generating:
| Field name | Technical abbreviation | Description and purpose of the field | Example of a valid value |
|---|---|---|---|
| Common Name | CN | The exact name of the Internet domain for which the issue is to be issued SSL certificate (with or without www). | webp.plor*.webp.pl(for Wildcard) |
| Organization name (Organization) | O | The official, full registered name of the company or institution (e.g. from the National Court Register/CEIDG). For private individuals, you can enter "None". | Company Name Sp. z o. o. |
| Department / Organizational Unit | OU | Name of the department in the company responsible for certification (optional field). | ITorSecOps |
| Locality | L | The physical location (headquarters) of your organization. | WarsaworKrakow |
| Voivodeship / State | S / ST | Voivodeship or region in which the organization is located (without Polish characters). | MazowieckieorMalopolskie |
| Country code | C | Two-letter country code according to the ISO 3166-1 alpha-2 standard. | PL, US, DE |
Private key security - the golden rule of cryptography
Asymmetric cryptography is based on a pair of related keys: a public key (contained in the CSR and the subsequent SSL certificate, visible to everyone) and **private key (PrivateKey)**.private.key) on your computer and upload it to the server during certificate installation.
