Köker GizliBilgi 1.0
An early .NET steganography application that hides text inside an image or audio carrier, reads it back later and provides optional password protection.
Köker GizliBilgi 1.0 was an early .NET steganography application I developed to place text inside an image or audio carrier and retrieve it later.
The user workflow allowed selecting the text and carrier file, producing a new output file and reading information back from a previously processed file. Optional password protection was also available.
Steganography Is Not Encryption
The project involved two different security goals: steganography attempts to conceal the existence of a message, while cryptography protects the message content from being understood without the required key material.
Hiding data in another file is therefore not a confidentiality guarantee. Likewise, the historical password option should not be interpreted as a claim that this old application implements current cryptographic best practice.
The broader technical and forensic context is covered in my Steganography article.
Carrier Integrity
A carrier that is resized, recompressed or transcoded after embedding can damage concealed data, depending on the method used. The transformations an embedding method can survive are therefore part of its practical behavior.
The surviving project record establishes the image/audio carrier, write/read workflow and optional password protection; unsupported implementation details are not part of the project description.
Release and Security Notes
The archived package size was 330 KB and its recorded MD5 was:
95366CF3AA816C4D4876C7601C2A1FA2I retain MD5 here only as historical release metadata; it is not a recommendation for modern integrity or signature design.
The old VirusTotal link similarly records the scan result for that package at the time rather than providing a current security guarantee.
