**Installing SSL Certificats in PfSense**

Summary:

✅ Generate a new private key + CSR inside pfSense
✅ Upload the CSR to Namecheap (Sectigo DV SSL)
✅ Import the resulting cert back into pfSense and assign it to HAProxy (or WebGUI)



✅ **STEP 1** — Generate a new private key + CSR in pfSense

1.	Log in to pfSense

2.	Go to:
   System → Cert. Manager → Certificates

3.	Click: + Add / Sign

4.	Choose:
   Method: Create a Certificate Signing Request (CSR)


Fill the form like this:

**Field**  ---------------->  **Value**\\
//Descriptive name  ---------------->  e.g. pilotreg-ssl-2025\\
Key Type  ---------------->  RSA (4096 bits) ← recommended\\
Digest Algorithm  ---------------->  SHA256\\
Common Name. ---------------->  *.yourdomain.com (or your exact domain)\\
Country / State / City  ---------------->  Fill as required\\
Email / Org  ---------------->  Optional unless required\\
//

👉 For wildcard certificates, use *.yourdomain.com

Click Save.

You will now see the CSR pending in the list.

5. Click the Download or View CSR icon next to it(looks like a magnifying glass)

Copy the CSR — it will look like:
   
-----BEGIN CERTIFICATE REQUEST----- \\ 
MIIC4jCCAc...\\
-----END CERTIFICATE REQUEST-----\\
   
✅ **STEP 2** — Upload CSR to Namecheap

1.	Log in to Namecheap\\
2.	Go to Products → SSL Certificates\\
3.	Next to your certificate click → Activate\\
4.	Paste the CSR you copied from pfSense\\
5.	Choose Web Server type: Other / Apache / Nginx (any works)\\
6.	Choose validation method (Email / DNS CNAME / HTTP)\\
\\
⚠️ I recommend DNS CNAME validation → fastest & easiest.\\
\\
Namecheap will then submit it to Sectigo.\\

✅ **STEP 3** — Once Namecheap issues the certificate\\

You will receive a ZIP file containing:\\
  * Your domain certificate (yourdomain.crt)\\
  * ntermediate CA (SectigoRSADomainValidationSecureServerCA.crt)\\
  * Root certificate (not needed for pfSense)\\

Unzip it.\\

✅ **STEP 4** — Import certificate into pfSense\\
1. Go to: System → Cert. Manager → Certificates\\
2. Edit the previously generated CSR entry\\
3. Choose: Import certificate\\
4. Paste:\\

Field  ---------------->  Paste\\
Certificate data  ---------------->  Contents of yourdomain.crt\\
Certificate Chain  ---------------->  Paste intermediate cert(s) from the ZIP\\

Example formatting:\\

-----BEGIN CERTIFICATE-----\\
(your domain certificate)\\
-----END CERTIFICATE-----\\
\\
-----BEGIN CERTIFICATE-----\\
(intermediate certificate)\\
-----END CERTIFICATE-----\\
\\
⚠️ Do NOT paste the private key, pfSense already has it stored since it created the CSR.

Click Save.
\\
✅ **STEP 5** — Configure pfSense / HAProxy to use the certificate\\

If used for the WebGUI:\\
System → Advanced → Admin Access → SSL Certificate → select new cert\\
If used in HAProxy:\\
Services → HAProxy → SSL Offloading (frontend)\\
Add → Select your new certificate\\
\\
Click Apply and reload.
\\
\\
🚨 **FINAL CHECK**
\\
go to:\\
   https://ssllabs.com/ssltest
and enter yourdomain.com to verify the chain.
\\
That's it!
