obfuscate 1.0.1

Dart CLI tool and library for text obfuscation and deobfuscation using custom mapping, Base64, ROT13, XOR, and string reversal.

Obfuscate

Text obfuscation toolkit for Dart — CLI and library.

Obfuscation, not encryption. Base64/ROT13/XOR/reverse/map ciphers give no real confidentiality — don't use this for anything that actually needs to stay secret.

Features

• CLI tool for quick obfuscation from the command line
• Dart library to integrate into your own projects
• Methods: Base64, ROT13, XOR (byte-safe), string reversal, character-substitution maps, word-token maps
• validateMap() catches bad maps (collisions, empty values, risky characters) before you use them
• NibbleCodec applies any codec safely to raw bytes, not just text

Install

dart pub global activate obfuscate

Usage

import 'package:obfuscate/obfuscate.dart';

const codec = Base64ObfuscationCodec();
final encoded = codec.obfuscate('Hello, World!');
final decoded = codec.deobfuscate(encoded);

// character map
final substitution = SubstitutionCodec({'h': 'x', 'e': 'y'});

// word map
final tokens = TokenSubstitutionCodec({'h': 'house', 'e': 'energy'});

Upgrading from an earlier version? The old Obfuscate.obfuscateBase64()-style static methods still work — deprecated, not removed, no code changes needed. See CHANGELOG.md.
