[Tool Suggestion] Midins Decryptor - Offline Recursive Decoder & Forensic Timeline

Hello,

Following the inclusion of my previous tool Midins Titan, I'd like to submit Midins Decryptor. It is a browser-based, 100% local-first tool designed for analysts to safely triage obfuscated artifacts.

Description

Midins Decryptor is a forensic-grade decoder that focuses on OpSec. It allows analysts to decode payloads (Recursive Base64, Hex, URL, etc.) and harvest secrets without ever leaking data to third-party online tools.

Key Features

• Recursive Cascade Decoder: Automatically detects and chains multiple encoding layers until the payload is fully resolved.
• Forensic Decoding Timeline: Every step of the transformation is recorded in a chronological timeline showing Input/Output lengths, byte deltas, and entropy evolution.
• Secret & Artifact Harvester: Real-time extraction of AWS keys, GitHub tokens, IPv4/v6, Emails, and URLs using hardened regex.
• Shannon Entropy Engine: Mathematical H(x) calculation to identify encrypted segments or high-entropy cryptographic keys.
• No-Egress Design: 100% offline-first. No external API calls, no analytics, no remote fonts. Can be run in fully isolated environments.

Why it's a great fit

OSINT investigations often involve suspicious strings that could contain sensitive internal data. Using "CyberChef-like" public clones is a risk. Midins Decryptor provides a professional, "Blue-Team" styled local environment to perform this triage safely and systematically.

Thank you!
