Multi-format encoding/decoding CLI with recursive layer detection for security analysis.

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

What It Does

  • Encode and decode Base64, Base64URL, Base32, Hex, and URL formats
  • Auto-detect encoding format with confidence scoring
  • Peel command recursively strips multi-layered encoding (WAF bypass analysis)
  • Chain multiple encoding steps to test obfuscation patterns
  • Pipeline-friendly output for integration into security workflows

Quick Start

uv tool install b64tool
b64tool encode "Hello World"

[!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

Commands

Command Description
b64tool encode Encode text into Base64, Base64URL, Base32, Hex, or URL format
b64tool decode Decode encoded text back to plaintext
b64tool detect Auto-detect the encoding format with confidence scoring
b64tool peel Recursively strip multi-layered encoding to reveal original data
b64tool chain Chain multiple encoding steps together for obfuscation testing
