SimpleAuthority is a graphical user interface (GUI) application designed to easily manage a private Public Key Infrastructure (PKI) without requiring specialist cryptographic or database knowledge. It allows you to set up your own internal Certificate Authority (CA) to generate, issue, and manage digital certificates for users, servers, and devices.
The tool is widely used for internal network security, homelabs, and development environments. Core Features
Zero External Dependencies: Unlike enterprise PKI systems, it does not require an external database or complex configuration. It is built directly on The Legion of the Bouncy Castle cryptographic library.
Cross-Platform Support: The tool runs smoothly across Windows, Mac OS X, and Linux operating systems.
Visual Status Management: It uses an easy-to-read, color-coded “traffic light” system (green, orange, red) to quickly identify which certificates are valid, expiring soon, or expired.
Broad Standard Support: It generates X.509 standards-compliant keys and certificates and handles Certificate Revocation Lists (CRLs). Common Use Cases
You can utilize SimpleAuthority to issue cryptographic digital identities for several internal security functions:
Secure VPN Access: Authenticating remote employees using certificates rather than weak username/password combos.
Server SSL Authentication: Securing internal web servers or services hosted on private domains (like .local or .test).
Client SSL Authentication: Enforcing secure access to restricted company wikis, development tools, or code repositories.
Digital Document & Code Signing: Signing internal executable files, scripts, or company PDFs and Word documents.
Secure Email: Enabling end-to-end digital signatures and encryption (SIME/MIME) in mail clients like Microsoft Outlook or Thunderbird. Step-by-Step: Setting Up SimpleAuthority
Building and running your internal CA with SimpleAuthority follows a simple, wizard-driven flow: 1. Installation & Environment Prep
Because the software generates and holds your root private keys, it is highly recommended to install SimpleAuthority on a dedicated, secure machine. Download the installer corresponding to your operating system via trusted repositories. 2. Creating the Root CA
When you launch the software for the first time, it will prompt you to create a new Certificate Authority.
Generate Entropy: The software will ask you to move your mouse or tap random keyboard keys to generate cryptographic randomness (entropy).
Set a Master Password: You must provide a strong master password. This password encrypts and protects your root CA private key. If this key is compromised, your entire internal security network is breached. 3. Enrolling Users and Servers
SimpleAuthority treats both people and computers as “Users”: Click the New User icon (or go to File -> New User). Input the user or server name.
Select the Certificate Type: choose General Purpose for individuals (emails/VPNs) or SSL Server for machines.
Define the validity period (typically 365 days) and click New Certificate to generate the identity. 4. Distributing Trust
Because you are running a private CA, operating systems and web browsers will not trust your certificates by default. You must export your public Root CA certificate and manually install it into the Trusted Root Certification Authorities store on all target employee laptops, servers, and mobile devices.
