Application which encrypts Unicode text UTF8 using a Vigenère polyalphabetic substitution cipher, converts the encrypted text to binary, then to 24 bit colors, then to a square png image of 10x10 pixel colored rectangles. The resulting image can be converted back to UTF8 text with this application and the proper keyword.
Setup file is in the archive: Text2Image.zip
Select a keyword that you and another party have agreed upon
Type or paste any UTF8 multilingual text and convert it to an image
Clear all
Recover an image by clicking recover and choosing a previously encoded png image
Using the wrong keyword retrieves only encrypted text from the image
