Overview

Simple SSL Certificate Manager is a streamlined API for automating SSL/TLS certificate lifecycle management. Built for security professionals and DevOps teams, it enables DNS-based domain validation, certificate generation via industry-standard protocols, and secure certificate delivery. The platform handles the complexity of certificate provisioning, allowing you to focus on securing your infrastructure.

This tool is ideal for organizations managing multiple domains, implementing Infrastructure-as-Code practices, or automating certificate renewals across distributed systems. With support for staging environments and flexible email validation, it accommodates both development and production workflows.

The API follows a two-step workflow: first generate DNS challenge records for domain ownership verification, then request certificate generation after DNS records are confirmed in place. Built-in debugging capabilities help troubleshoot DNS configuration issues.

Usage

DNS Challenge Generation

First, generate DNS challenge data for domain validation:

POST /dns-challenge
Content-Type: application/json

{
  "domain": "example.com",
  "email": "admin@example.com"
}

Sample Response:

{
  "domain": "example.com",
  "challenge_token": "abc123xyz789",
  "dns_record_type": "TXT",
  "dns_record_name": "_acme-challenge.example.com",
  "dns_record_value": "abc123xyz789_validation_string",
  "challenge_expires_at": "2025-01-15T14:30:00Z"
}

Certificate Generation

After DNS records are in place, request certificate generation:

POST /generate-certificate
Content-Type: application/json

{
  "domain": "example.com",
  "email": "admin@example.com",
  "confirmed": true,
  "staging": false
}

Sample Response:

{
  "certificate_id": "cert_67890abcde",
  "domain": "example.com",
  "status": "issued",
  "issued_at": "2025-01-15T14:35:00Z",
  "expires_at": "2026-01-15T14:35:00Z",
  "certificate_name": "example_com_2025",
  "download_url": "/download/example_com_2025/certificate.pem"
}

Debug DNS Configuration

Verify DNS setup before certificate generation:

GET /debug/example.com

Sample Response:

{
  "domain": "example.com",
  "dns_records": [
    {
      "name": "_acme-challenge.example.com",
      "type": "TXT",
      "value": "abc123xyz789_validation_string",
      "status": "verified",
      "ttl": 300
    }
  ],
  "validation_status": "success",
  "checked_at": "2025-01-15T14:33:00Z"
}

Endpoints

}

POST /generate-certificate

Summary: Generate Certificate

Description: Generate SSL certificate after DNS verification is confirmed.

Parameters:

• domain (string, required): The domain name for certificate issuance
• email (string, email format, required): Contact email for the certificate
• confirmed (boolean, optional, default: false): Set to true after DNS records are verified
• staging (boolean, optional, default: false): Use staging certificates for testing

Response Shape:

{
  "certificate_id": string,
  "domain": string,

}

GET /download/{cert_name}/{filename}

Summary: Download Certificate

Description: Download generated certificate files (PEM, key, chain).

Parameters:

• cert_name (string, required): Certificate identifier (from generation response)
• filename (string, required): File to download (certificate.pem, private.key, or chain.pem)

Response: Binary certificate file content or JSON error.

GET /debug/{domain}

Summary: Debug Domain

Description: Inspect DNS configuration and validation status for a domain.

Parameters:

• domain (string, required): Domain name to debug (e.g., example.com)

Response Shape:

      "ttl": integer
    }
  ],
  "validation_status": string,
  "checked_at": string (ISO 8601 datetime)
}
