XOR Notes.zip by Chuck Mire (Rate this file/View comments) |
This is further discussion on using XOR where an XOR encrypted file is sent to a receiver without exchanging keys. There is potentially a problem with this method resulting from a "Man-In-The-Middle", which is explained in full. A safer way to do this involves using my program CRC32.exe which is available here: http://www.qb45.org/files.php?action=showfile&id=1662 The attached zip file has an example I created for your review as well as a screen shot of the CRC32.exe entry that I document in an included XOR Notes.txt file. |

ZIP In A PICture.zip by Chuck Mire (Rate this file/View comments) |
ZIP In A PICture is a Windows executable that allows a .7z or .zip compressed file to be hidden within a .gif, .jpg, .jpeg, or .png picture file. In order to extract the results, the Windows freeware program, 7-Zip File Manager, is required. The results allow the casual user only the ability to view the picture file without knowing about it's hidden content. However, any experienced user with a minimal skill set would be able to view and extract the hidden contents. The latest versions of Windows 7-Zip is here: http://www.7-zip.org/ The zip file contains the Windows executable, the source code, a PDF with screen shots and documentation, plus a sample .jpeg file. |

ZIP In Other TYPES.zip by Chuck Mire (Rate this file/View comments) |
The zip file, ZIP In Other TYPES.zip, contains two (2) Windows executables with source code: (1) ZIP In A MIDI and (2) ZIP In A PDF. Each program works EXACTLY like my previous post, ZIP In A PICture. The difference is the ability to hide a compressed file in any .mid or .pdf file, respectively. Once again each of these programs is designed to be used in conjunction with the Windows freeware program, 7-Zip. Since the interface has not changed, refer to my PDF that was included in my previous post, ZIP In A PICture.pdf, for documentation. |
