Steganography Text Decoder

This tool decodes hidden information embedded in plain text using multiple steganography schemes. It accepts a text input and optional method hint, then returns the extracted payload, along with the method used and a confidence score. It is designed for security researchers, educators, and incident responders evaluating suspected steganographic content.
The core logic implements punctuation-based, whitespace-based, and character-code LSB decoding, plus simple pattern schemes. It can auto-detect the most probable method or follow a user-specified approach. Outputs include decoded_text, method_used, and a numeric confidence indicator to guide interpretation.
Use cases include verifying classroom demonstrations, auditing textual data for covert messages, or forensic investigations. Unique value lies in combining several decoding strategies in a single pass and providing structured metadata. Edge cases like no payload, insufficient length, or non-text input are reported with clear notes, not results, to prevent misinterpretation.
