One of the most significant advantages of DV (Domain Validation) SSL is its issuance speed. After payment and domain verification, the certificate is issued and ready to install within 15 minutes.
1. How Fast Is DV SSL Compared to OV and EV?
| Type | Issuance Time | Verification Required | Price |
|---|---|---|---|
| DV (Domain Validation) | 15 minutes ✅ | Domain only | ฿1,000+/yr |
| OV (Organization Validation) | 1–3 business days | Domain + company | ฿4,000+/yr |
| EV (Extended Validation) | 3–7 business days | Domain + company + executives | ฿7,000+/yr |
DV SSL is the fastest because the verification process is minimal. The CA only checks that you genuinely own the domain — through email, DNS record, or a file on your server.
2. The DV SSL 15-Minute Issuance Process
- Purchase SSL — Select the RapidSSL or GeoTrust DV plan at AsiaGB
- Generate CSR — Create a Certificate Signing Request via DirectAdmin or OpenSSL
- Choose Domain Validation method — 3 options:
- Email Validation — Receive an email at [email protected] or [email protected]
- DNS Validation — Add a CNAME record the CA specifies in your DNS
- File Validation — Upload a specified .txt file to your web server
- Verify domain — Complete your chosen validation method
- Receive certificate — CA issues the certificate via email within 15 minutes
- Install certificate — Via DirectAdmin SSL section or your server
Fastest tip: Choose DNS Validation — no waiting for email or checking files. Add the CNAME record and the CA verifies automatically.
3. What Types of Websites Is DV SSL Right For?
DV SSL is sufficient for the vast majority of websites:
- Blogs, content sites, portfolios
- Company websites that don't accept payment directly
- E-commerce using external payment gateways (PromptPay QR, Stripe, Omise)
- APIs requiring HTTPS
- Personal sites or internal systems
OV or EV is more appropriate when compliance requirements dictate it, or when displaying the company name in the certificate is important.
3.1 Comparing Leading CAs: RapidSSL, GeoTrust, and DigiCert
Once you've decided on DV SSL, the next step is choosing the right Certificate Authority (CA) for your needs and budget. Here's a comparison of the CAs available through AsiaGB:
| CA / Product | 1-Year Price | Warranty | Best For |
|---|---|---|---|
| RapidSSL | ฿1,000/yr | USD 10,000 | Blogs, portfolios, SME websites |
| GeoTrust QuickSSL Premium | ฿3,000/yr | USD 500,000 | E-commerce, applications |
| DigiCert (Secure Site) | ฿13,069/yr | USD 1,750,000 | Enterprise, financial services |
For most websites, RapidSSL DV at ฿1,000/year offers the best value. Every modern browser — Chrome, Safari, Firefox — trusts it equally regardless of the CA tier.
3.2 Generating a CSR with OpenSSL on Linux/macOS
If you're not using DirectAdmin or prefer to generate your own CSR, OpenSSL is the standard tool:
Create a Private Key and CSR
# Generate a 2048-bit Private Key
openssl genrsa -out yourdomain.key 2048
# Generate the CSR from the key
openssl req -new -key yourdomain.key -out yourdomain.csr
# Answer the prompts:
# Country Name: TH
# State: Bangkok
# Locality: Bangkok
# Organization: (your company or personal name)
# Common Name: yourdomain.com (the domain you want secured)
Send the contents of yourdomain.csr to AsiaGB to process your certificate order. Keep yourdomain.key secure — never share it with anyone.
RSA 4096 vs 2048: RSA 2048-bit is the widely accepted security standard and is approximately 4× faster than 4096-bit during TLS handshakes. Security experts generally recommend 2048 for web servers. Reserve 4096 for systems with exceptionally high security requirements.
4. How to Renew DV SSL
DV SSL has a 1-year validity period (industry standard since 2020). Renewal process:
- Notify support or renew through the client portal at least 30 days before expiration
- Generate a new CSR (recommended for key rotation)
- Complete the Domain Validation process again
- Install the new certificate in place of the old one
⚠️ Never let your SSL expire: Browsers will show "Your connection is not private," causing visitors to leave immediately. This severely damages both SEO and customer trust.
4.1 Installing Your SSL Certificate on DirectAdmin
After receiving the certificate files from the CA via email (typically a .crt or .pem file), follow these steps to install on DirectAdmin:
- Log in to DirectAdmin → navigate to SSL Certificates
- Select Paste a pre-generated certificate and key
- Paste your Private Key (
.key) in the left field - Paste your Certificate (
.crt) in the right field - Paste the CA Bundle (Intermediate Certificate) in the CA Cert field if provided
- Click Save — SSL activates immediately
Verify your SSL after installation: Use AsiaGB's SSL Server Test to confirm the certificate is valid, covers both www and non-www, and has no certificate chain issues.
5. Frequently Asked Questions
What's the difference between Let's Encrypt and a purchased DV SSL?
Let's Encrypt is free and works well for general websites. Purchased DV SSL includes a higher warranty, CA support, and a more professional appearance. For SME e-commerce, a paid SSL may convey more credibility to certain customer segments.
Does DV SSL cover both www and non-www?
Yes. The certificate automatically covers both domain.com and www.domain.com.
What's the difference between DV and Wildcard SSL?
DV covers only the main domain and www. Wildcard covers *.domain.com (all subdomains) — ideal for sites with multiple subdomains like shop.domain.com, blog.domain.com.
What should I do after my SSL certificate is installed?
After successfully installing your SSL certificate, take these follow-up steps. First, configure a Force HTTPS Redirect in your .htaccess file or via DirectAdmin so that visitors who type http:// are automatically redirected to https://. Second, if you use WordPress, update the siteurl and home values in Settings → General to the https:// version. Third, submit your updated sitemap to Google Search Console so Google recognizes the HTTPS migration. Finally, set a calendar reminder to renew at least 30 days before expiration to avoid any certificate lapse. These steps ensure your SSL investment delivers maximum SEO and security benefit from day one.
