obfuscate 1.0.1

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

1.0.1

• resolved Pub analyzer warning

1.0.0

Redesigned the codec architecture.Old data and old code both keep working:

Added

• SubstitutionCodec and TokenSubstitutionCodec — typed replacements for the old character-map obfuscation, split by whether a map goes char-to-char or char-to-word
• NibbleCodec — safely applies any codec to raw bytes, not just text.
• validateMap() — checks a map for duplicate values, empty entries, and risky characters (like combining marks) before you use it.
• VersionedObfuscationMethod — lets you decode both old- and new-format data through one call, based on an explicit version rather than guessing.
• Proper exceptions (ObfuscationException and subtypes) instead of silent failures.

Fixed

• XOR obfuscation could corrupt data when writing to UTF-8 (invalid surrogate sequences for some key/input combos). Now operates on bytes and outputs base64.
• Map-based obfuscation inserted a stray delimiter between every character and silently ate original whitespace on decode.
• deobfuscateBase64 used to return the input unchanged on a bad decode instead of signaling failure.

Deprecated

• The old static Obfuscate class (obfuscateBase64, obfuscateWithMap, etc.) is deprecated but still works exactly as before — no code changes required.

Compatibility

• Data obfuscated with 0.0.1 still decodes correctly via LegacyMapCodec and the deprecated Obfuscate methods.
• New code should use the codec classes above instead.
