A Certificate Signing Request (CSR) is required to apply for an SSL certificate. Fill in your domain and organization details below to instantly generate your CSR code and Private Key.
Domain: CN - Common Name. Company: O - Organization. Division: OU - Org Unit. City: L - Locality. State: ST - State. Country: C - 2-letter code.
A CSR is a block of encoded text that contains information about your organization and the domain you want to secure. You submit the CSR to a Certificate Authority (CA) such as Comodo, and they use it to issue your SSL certificate. Your Private Key is generated at the same time and must be kept secret — it is used to install and activate the certificate on your server.
Never share your Private Key. Store it securely on your server. It cannot be re-generated if lost without re-issuing the certificate.
For a single domain use yourdomain.com or www.yourdomain.com. For Wildcard SSL use *.yourdomain.com.
2048-bit is the industry standard and recommended for most use cases. 4096-bit provides higher security but may slow TLS handshakes on older devices.
SHA-256 with RSA is the standard signature algorithm required by all modern browsers and Certificate Authorities. SHA-384 is also acceptable for higher security requirements.
