Post-access credential exposure detection for Linux systems, written in Nim.

This is a quick overview. Security theory, architecture, and full walkthroughs are in the learn modules.

What It Does

• Scans Linux home directories for exposed credentials across 7 categories
• Detects unprotected SSH keys, plaintext cloud credentials, browser credential stores, shell history secrets, keyrings, Git tokens, and application credentials
• Classifies findings by severity based on file permissions and exposure risk
• Reports in terminal with color-coded output or structured JSON for automation
• Compiles to a single static binary with zero runtime dependencies

Quick Start

bash install.sh
credenum

[!TIP] This project uses just as a command runner. Type just to see all available commands.

Install: curl -sSf https://just.systems/install.sh | bash -s -- --to ~/.local/bin

Stack

Language: Nim 2.2+ (ORC memory management)

Build: Just, Nimble, musl (static linking), UPX (compression), zigcc (cross-compilation)

Testing: Nim unittest, Docker (integration tests with planted credentials)
