# Implementing Secure Random Generation

## Overview

Use cryptographically secure random number generators for tokens, keys, nonces, and security-critical operations.

## Prerequisites

| Tool / Requirement | Details |
|---|---|
| `secrets-module` | Security tooling |
| `os-urandom` | Security tooling |
| `openssl` | Security tooling |
| Isolated lab environment for testing | Environment requirement |
| Authorization and signed Rules of Engagement (RoE) | Environment requirement |
| Relevant target samples or systems acquired through authorized channels | Environment requirement |

## Quick Reference

```bash
# Initialize working environment
mkdir -p /tmp/implementing-secure-random-generation/{output,logs,artifacts}

# Execute primary analysis with secrets-module
echo "[*] Running Implementing Secure Random Generation with secrets-module..."

# Validate results with os-urandom
echo "[*] Cross-validating with os-urandom..."

# Generate summary report
cat /tmp/implementing-secure-random-generation/output/report.json
```

## Workflow

### Step 1: Preparation and Reconnaissance

```bash
# Identify target and gather initial intelligence
file ./target_sample
secrets-module --version 2>/dev/null || echo "Install secrets-module"

# Set up working directory
mkdir -p /tmp/implementing-secure-random-generation/{output,logs,artifacts}
```

### Step 2: Primary Analysis

```bash
# Execute primary analysis with secrets-module
# Refer to Quick Reference above for detailed commands
echo "[*] Running Implementing Secure Random Generation with secrets-module..."

# Log all operations
script -q /tmp/implementing-secure-random-generation/logs/session.log
```

### Step 3: Deep Investigation

```bash
# Apply os-urandom for secondary analysis
echo "[*] Deep investigation with os-urandom..."

# Cross-reference findings
diff /tmp/implementing-secure-random-generation/output/primary.json /tmp/implementing-secure-random-generation/output/secondary.json
```

### Step 4: Documentation and Reporting

```bash
# Generate structured findings report
cat <<'EOF' > /tmp/implementing-secure-random-generation/output/report.json
{
  "technique": "implementing-secure-random-generation",
  "domain": "secure-coding",
  "tools_used": ["secrets-module", "os-urandom"],
