A CSR (Certificate Signing Request) is a block of text that you create and send to the certificate authority to get a paid SSL certificate. It contains your domain, company details and the public key.
In short
- A private key is created together with the CSR; keep it safe.
- With Let's Encrypt you do not need a CSR; Plesk does everything automatically.
What does a CSR contain?
| Field | Example |
|---|---|
| Domain (CN) | yourdomain.com; for a wildcard *.yourdomain.com |
| Organisation (O) | Your Company Ltd. (can be left empty for DV) |
| City / Country | London / GB |
| Key size | 2048 bits (standard) |
How do I create a CSR?
If your site is on webevi hosting, the easiest way is Plesk: How do I create a CSR in Plesk? The panel keeps the private key for you.
For another server you can use our free CSR Generator:
- Open the CSR Generator page.
- Enter the domain, organisation, city, country and email; leave the key size at 2048.
- Click Generate CSR. Paste the CSR into your certificate order and save the private key somewhere safe.
You can view the contents of an existing CSR with the CSR Decoder.
