CSR Generator for Splunk

Overview

CSR Generator is a Splunk app that allows users to generate a Certificate Signing Request (CSR) and a private key directly from a simple dashboard UI inside Splunk.

The app leverages the OpenSSL binary bundled with Splunk (splunk cmd openssl) and is fully compatible with Windows and Linux environments.

Release History

Date Version Notes
2024-10-04 0.0.1 Initial release
2024-10-12 0.0.2 Added subjectAltName support, improved input handling, bug fixes
2025-05-21 0.1.0 Major UI/UX redesign, improved CSR engine, full Windows/Linux support

Dashboard

Syntax

| gencsr common_name=<string> country=<string> state=<string> locality=<string> organization=<string> organizationalunit=<string> password=<string> subjectaltname=<string>

Example

| gencsr common_name="example.com" country="US" state="CA" locality="San Francisco" organization="Example Inc." organizationalunit="IT" password="securepassword" subjectaltname="www.example.com,mail.example.com"

Features

  • Generates CSRs using OpenSSL standards.
  • Full cross-platform support (Windows and Linux).
  • Customizable fields: Common Name (CN), Country (C), State (ST), Locality (L), Organization (O), Organizational Unit (OU), and SubjectAltName (SAN).
  • Password protection for the generated private key (PKCS#8 PEM format).
  • Secure in-memory handling of key and CSR (temp files are securely deleted).
  • Outputs CSR and private key directly to the Splunk UI for easy copy/paste.
  • User-friendly dashboard UI with real-time validation and dynamic SAN input.
  • Integrated with Splunk SPL as a custom GeneratingCommand.

New in Version 0.1.0

  • ✅ Complete UI redesign with two-panel layout (form on left, output on right).
  • ✅ Dashboard restyled for clarity, readability, and modern UX.
  • ✅ Full compatibility with Splunk on Windows (no more stdin issues).
  • ✅ Sanitized OpenSSL output (writing RSA key line removed).
  • ✅ Clear separation between logic, layout, and style (JS / CSS / XML).
  • ✅ Responsive design with clean layout for enterprise use.

Known Limitations

  • OpenSSL must be available via splunk cmd openssl.
  • Input validation checks only basic structure (e.g., valid characters in SAN/CN).
  • The app executes synchronously — high-volume CSR generation may require performance tuning.
  • Some OpenSSL validation errors are surfaced raw from stdout/stderr.

Release Notes

Version 0.1.1
June 18, 2025
  • Minor Fixes
Version 0.1.0
May 21, 2025
  • UI rebuilt using modular SimpleXML layout with custom JS/CSS separation and explicit grid logic.
  • Decoupled rendering logic from command execution to improve maintainability and cross-browser behavior.
  • Replaced STDIN key handling with file-based input to ensure openssl works reliably on both Windows and Linux.
  • Output normalization: removed injected OpenSSL stderr content and ensured raw PEM output for both CSR and private key.
  • Refactored dashboard styling using scoped selectors and isolation-friendly CSS to avoid conflict with Splunk base styles.
  • Optimized DOM structure for better performance and rendering inside Splunk’s Web Framework under constrained environments.
Version 0.0.2
Oct. 11, 2024

New Features:

  • SAN Support: Specify multiple Subject Alternative Names for greater flexibility.
  • Dynamic Fields: Add or remove SAN fields in the CSR form.
  • Improved Validation: Enhanced checks for common name, country, state, and organization fields.

Improvements:

  • Default Values: Automatically apply defaults (e.g., "US" for country) for empty fields.
  • UI Enhancements: Better layout for CSR and key output display.
  • Optimized OpenSSL Process: Simplified CSR creation when no SAN is provided.

Bug Fixes:

  • CSR Output: Resolved issues with missing common name in the CSR.
  • Field Truncation: Fixed incorrect truncation of "N/A" fields.
  • Display Issues: Corrected CSR and key output visibility in the dashboard.
