A controlled, ethical brute-force utility designed for authorized security testing and penetration testing engagements. Unlike traditional brute-force tools that flood systems recklessly, SafeBruteForce prioritizes safety, user control, and system preservation.

  SafeBruteForce v0.1.0 - Controlled Ethical Testing
  ⚠️  For Authorized Security Testing Only ⚠️

🔍 Why SafeBruteForce?

Traditional brute-force tools are reckless: - ❌ Flood systems with uncontrolled requests - ❌ Risk account lockouts and service disruption - ❌ Generate millions of lines of verbose output - ❌ No graceful pause or resume capability - ❌ Difficult to track progress

SafeBruteForce redefines brute-forcing as a controlled, pausable process: - ✅ Automatic safety pauses every 25 attempts - ✅ User confirmation required to continue - ✅ Clean, filtered output - only see what matters - ✅ Checkpoint/resume for long operations - ✅ Rate limiting to respect system resources - ✅ Progress tracking with ETA calculations - ✅ Concurrent architecture using Erlang/OTP

📦 Features

🛑 Safety Mechanisms

• Automatic Pause: Stops every 25 attempts, requires user confirmation

• Manual Controls: Pause, resume, and check status at any time

• Rate Limiting: Token bucket algorithm for controlled request rates

• Authorization Checks: CLI prompts for explicit authorization

• Audit Logging: Comprehensive activity logs for accountability

🔧 Pattern Generation

• Wordlists: Load from files with optional mutations (leet speak, capitalization)

• Charset Combinations: Generate all permutations from character sets

• Sequential Patterns: Number ranges, dates, common formats

• Custom Generators: Implement your own pattern strategies

• Built-in Recipes: PIN codes, common passwords, hex colors

🎯 Target Support

• HTTP/HTTPS: Test web login forms with custom headers and body formats

• Custom Functions: Integrate with any validation logic

• Mock Targets: Test functionality without external dependencies

• Extensible: Easy to add new target types (SSH, FTP, etc.)

📊 Result Management

• Filtered Output: See successes only, failures only, or all results

• Statistics Dashboard: Attempts, success rate, elapsed time, rate per second

• Export Capabilities: Save results to files for analysis

• Pattern Tracking: Automatic recording of successful patterns

🔄 Operational Features

• Checkpoints: Auto-save and manual checkpoint creation

• Resume Capability: Restore from checkpoints to continue interrupted sessions

• Progress Tracking: Real-time progress bars with ETA

• Async Execution: Run operations in background

• Supervision Trees: OTP fault tolerance for reliability

(let ((pattern-generator
       (lambda ()
         (let ((company "AcmeCorp")
               (years (lists:seq 2020 2025)))
           (lists:flatmap
