Features

Table Definitions

• Hide to a basic level - the process of hiding data in a way that may be identified through moderately simple detection methods
• Hide with mapping - hiding the data using a map to do so
• Hide reasonably well - hiding data in a way that may not be reliably identified through moderately simple detection methods
• Hide and Encrypt - the process of encrypting data so that if/ when it is recovered, there is a decreased chance of successful extraction
• Detection - the process of identifying if there is a high chance of hidden data. Use detectSteg for this.
• Visual - perform some sort of visual analysis to identify potential hidden data. Use visual for this.

• imagelsb

  Use LSB steganography to encode and optionally encrypt and set up a mapping for data.

• homoglyphs

  Use similar characters to hide data and optionally encrypt and set up a mapping for data.

• soundlsb

  Use LSB steganography to encode and optionally encrypt and set up a mapping for data.

• fileappend

  Append data to various file formats

• msoffice

  Use file inclusion and XML comments to hide data in Microsoft Office documents

• odf

  Use file inclusion and XML comments to hide data in OpenOffice/ LibreOffice documents

• zerowidth

  Use zero length chars to encode data

Roadmap

For completed components, see the changelog (link below)

• fileappend

  can probably append to all sorts of formats so investigate this more
