Here's the challenge:
Below is a link to a small, 14K, file called challenge.
It is just composed of ASCII characters.
The SHA1 checksums for these two files are:
// // File Checksum Integrity Verifier version 2.05. // 836ae413481b21d49fa5a9cefe1304c8 challenge
Perhaps my inability to figure out how one would decrypt this file without all the parameters only shows my ignorance of cryptography.
With Yull I have strived to make it easy to protect your data and near impossible for an adversary to retrieve it without your cooperation.
I think I have succeeded, but of course, I cannot prove a negative.
You can read the White Paper here on the web site to learn how Yull works. Perhaps that's some help.
PROVE ME WRONG! SHOW ME YULL IS A FAILURE!
I will answer questions (if they are useful for the rest of the community) about these files.
$100 to the first person who can email me the correctly decryted file challenge.
RORetc and that is mathematical. I have corrected that.
