[ale] OT: MD5 checksums & math

[randy.janinda at ndcorp.com (Randy Janinda)]

Not for the meek hearted:

Let me try to explain this request. 

I have four images. I know the md5sum of three of them and I want to
predict the md5sum of the fourth. 

Here's the facts:

ImageA is the same as ImageB except on minor addition to ImageB (we'll
call this addition X).

md5sums:

ImageA = c76ada9f51c10ee6ccbc9bccd2e05358
ImageB = 53485d8e8171766b533d13d2df0ffa97 (ImageA + X)
ImageC = b64a84171c956e14aab561b1545cbc70

Now assuming ImageD has the same exact addition as ImageB (the X
factor) can I predict the md5sum by adding that "X" factor to ImageC?

ImageD = ImageC + X


Is that clear enough? Does anyone have any ideas?

Thanks,
Randy
