How to Obtain SSL Certificate Without Registered Company: CSR Generation Guide for Solo Developers

When generating a Certificate Signing Request (CSR) for your web project, most CAs (Certificate Authorities) request organization details that match official business registrations. This creates a catch-22 for solo developers:

# Typical OpenSSL CSR generation command requiring organization details
openssl req -new -newkey rsa:2048 -nodes -keyout server.key -out server.csr
# Prompts for:
# Country Name (2 letter code) []
# State or Province Name (full name) []
# Locality Name (eg, city) []
# Organization Name (eg, company) [] <-- Problem field
# Organizational Unit Name (eg, section) []
# Common Name (eg, your domain) []
# Email Address []

Option 1: Use Domain Validation (DV) SSL certificates instead of Organization Validation (OV). DV certificates only verify domain ownership:

# Example with Let's Encrypt (DV certificates)
sudo certbot certonly --manual --preferred-challenges=dns -d yourdomain.com
# No organization verification needed

Option 2: When forced to enter organization name in CSR:

  • Use your project name followed by "Project" (e.g., "SocialApp Project")
  • Some CAs accept "Individual" or "Sole Proprietor" as organization
  • Never claim legal status you don't possess (e.g., "Inc", "LLC")

Here's how to generate a CSR without official organization details:

openssl req -new -newkey rsa:2048 -nodes -keyout myserver.key -out myserver.csr \
-subj "/C=US/ST=California/L=San Francisco/O=MyWebProject/OU=Development/CN=mydomain.com"

Key parameters for solo devs:

  • /O=: Your project name (avoid legal-sounding suffixes)
  • /OU=: "Development" or "Web Services"
  • /CN=: Must match your exact domain

Different CAs have varying policies:

CA Solo Developer Policy
Let's Encrypt No organization verification
Sectigo Accepts "Individual" as organization
DigiCert Requires legal verification for OV/EV

While technically possible, be aware that:

  • Using false business information violates most CA agreements
  • Enterprise clients may verify your certificate details
  • For commercial sites, consider registering as DBA (Doing Business As)

Remember: Domain Validation (DV) certificates provide identical encryption as OV/EV certificates, just without organization verification.


When generating a Certificate Signing Request (CSR) for your web project, most Certificate Authorities (CAs) require an Organization Name field that matches legal business registration. This creates challenges for solo developers bootstrapping projects:

openssl req -new -newkey rsa:2048 -nodes -keyout myserver.key -out server.csr

Examining the CSR fields more closely:

  • Common Name (CN): Must match your domain (e.g., www.yoursite.com)
  • Organization (O): Typically requires legal registration
  • Organizational Unit (OU): Often optional

Workarounds for unregistered entities:

# Option 1: Use individual validation
Country Name (2 letter code) [XX]:US
State or Province Name (full name) []:California
Locality Name (eg, city) []:San Francisco
Organization Name (eg, company) []:YourProjectName
Organizational Unit Name (eg, section) []:Web Services
Common Name (eg, your name or server's hostname) []:www.yourproject.com
Email Address []:admin@yourproject.com

Many CAs will accept this for Domain Validated (DV) certificates, which only verify domain ownership rather than legal entity status.

Different CAs handle this differently:

  • Let's Encrypt: Completely automated, no manual O field verification
  • Comodo/Sectigo: May accept project names for DV certs
  • DigiCert: Stricter verification for OV/EV certificates

For Node.js applications using Express:

const https = require('https');
const fs = require('fs');

const options = {
  key: fs.readFileSync('server.key'),
  cert: fs.readFileSync('server.crt')
};

https.createServer(options, (req, res) => {
  res.writeHead(200);
  res.end('Secure connection established');
}).listen(443);

While technically possible to use your project name:

  • Not misrepresenting as a legal entity is crucial
  • Consider adding "Project" or "Initiative" to the name
  • Some jurisdictions may require DBA registration for certain names

Other technical solutions worth considering:

  • Cloud provider managed certificates (AWS ACM, Google Cloud SSL)
  • Reverse proxy solutions (Cloudflare SSL, NGINX termination)
  • Wildcard certificates for multiple subdomains
