I made a program called "cryptex". Although it has several limitations and severe drawbacks - I think that the security is quite strong here's how it works : The file to be encrypted must be below 0FFFFFh bytes - or 1mb. A keyfile is generated exactly 1mb of size. the keyfile contains FFFFF random bytes. When encrypting - the program loads byte 1 of keyfile and byte 1 of target and it xors. then it moves on to 2 and to 3 ... to the end of the file. Each source byte is xored with a totally different byte from the keyfile. So exactly how secure is this? Thanks note : an early version is included cryptex.rar

As some of you will know, I have written a packer (haven't we all) What is the best way to get files compressed by my packer to be known by AV companies as safe? Is there some site to upload files for processing, like VirusTotal but the other way round? The loader code is very simple, so smart AV software will probably have no problem unpacking it and checking for malware, but I mean for the others that detect everything unknown as suspicious. Have fun! BoB
