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, and bug fixes

Overview

This app generates a Certificate Signing Request (CSR) and a private key directly within Splunk using OpenSSL.

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.
  • Customizable fields: Common Name (CN), Country (C), State (ST), Locality (L), Organization (O), Organizational Unit (OU), and subjectAltName.
  • Handles CSRs and private keys securely in-memory; no files are written to disk.
  • Option to password-protect the generated private key.
  • Outputs the CSR and private key directly in search results for easy access.
  • Seamless integration with Splunk’s SPL via a custom GeneratingCommand.
  • Default values provided for optional parameters, but users can override them.

New in Version 0.0.2

  • Added support for subjectAltName in CSRs.
  • Improved handling of optional input fields with defaults.
  • Enhanced input validation to prevent empty fields.
  • Minor bug fixes and performance improvements.

Known limitations

  • OpenSSL must be installed and properly configured in the Splunk environment.
  • Limited input validation — invalid fields, like incorrect country codes, may cause CSR generation to fail.
  • Dependence on external OpenSSL tools, so the app won't work if OpenSSL is missing or misconfigured.
  • Commands are executed synchronously, which could slow performance if multiple CSRs are generated in parallel.
