A CA certificate (Certificate Authority certificate) is a digitally signed X.509 credential issued by a trusted Certificate Authority. It serves two primary purposes:
- Root of Trust
The CA certificate represents the ârootâ or âintermediateâ authority that vouches for the authenticity of all certificates it issues. Clients (browsers, operating systems, applications) include CA certificates in their trust stores so they can validate any server or client certificate chained back to that CA. - Signature Anchor
Each endâentity certificate (for a website, device, or user) bears a digital signature created by the CAâs private key. Verifying that signature against the public key in the CA certificate ensures the certificate hasnât been tampered with and was indeed issued by the trusted authority.
How to Request an SSL/TLS CA Certificate from eMudhra
Requesting an SSL/TLS certificate from eMudhraâs CA is a streamlined, APIâdriven process designed for both selfâservice and enterprise workflows. Below is a stepâbyâstep guide:
- Prepare Your Certificate Signing Request (CSR)
- Generate a Key Pair: On your server or in your HSM, create a new private key (RSA or ECC) and corresponding CSR.
- Populate CSR Fields: Include your fully qualified domain name (FQDN) in the Common Name (CN) or Subject Alternative Name (SAN) fields, together with organization details (O, OU, L, ST, C) as required for OV/EV validation.
- Log In to the eMudhra Developer Portal
- Access Account: Navigate to the eMudhra PKI Portal and authenticate using your corporate credentials or API token.
- Navigate to Certificate Services: Select âSSL/TLS Certificatesâ from the menu to open the issuance dashboard.
- Choose Certificate Profile & Validity
- Select Validation Level: Pick DomainâValidated (DV), OrganizationâValidated (OV), or ExtendedâValidation (EV) based on your security requirements.
- Define Validity Period: Choose your term (1, 2, or 3 years) and any additional addâons (wildcard, SANs).
- Submit CSR & Payment
- Upload CSR: Paste the PEMâencoded CSR into the portal form or reference it via API.
- Review Order: Confirm domain names, validity term, and organizational information.
- Complete Payment: Pay via credit card, bank transfer, or invoice (for enterprise accounts).
- Undergo Validation
- Automated Domain Check: For DV certificates, eMudhra sends a verification email or prompts you to create a DNS record.
- Manual Organization Audit: For OV/EV, provide business documents (e.g., incorporation certificate, address proof) through a secure upload widget.
- Download & Deploy Certificate
- Retrieve Certificate Bundle: Once issued, download the server certificate, any intermediate CA certificates, and the root bundle in PEM or PKCS#7 format.
- Install on Your Server: Configure your web server, load balancer, or appliance with the certificate chain and private key.
- Validate Installation: Use online SSL checkers or the eMudhra portalâs healthâcheck tool to verify correct installation and chain integrity.
Tips for a Smooth Request
- Use API for Automation: Integrate with eMudhraâs RESTful API to programmatically request, renew, and revoke certificates as part of your CI/CD pipeline.
- Leverage HSM Integration: Generate and store private keys within FIPSâcertified HSMs to prevent key exposure. eMudhraâs CA can directly ingest keys from supported HSMs.
- Enable AutoâRenewal: Configure Certificate Lifecycle Management policies to trigger renewal requests automatically before expiry, avoiding any service interruption.
By understanding what a CA certificate is and following eMudhraâs guided request process, organizations can rapidly secure their web applications and APIs with trusted SSL/TLS credentialsâbacked by enterpriseâgrade validation, automation, and HSMâlevel key protection.
