Hi all, first, just wanna say thanks because this is my first post, but I've already learned a ton just by reading stuff on this forum. Great place.
Anyway, I have a database that has me stumped. Some of the entries in one of the tables are hex, and the number of hex bits is the same length as the number of characters for the entry should be. For example, this is how it stores 02/15:
Code: | \x9c\x82\x91\xff\xf9 |
I know what that was is supposed to be, because I've been storing info in the DB through the website interface in an attempt to figure out the encoding. The problem is, there is sometimes overlap, i.e., sometimes a letter will have the same hex value in one entry as a number in the other. Also, sometimes the same character in two different fields results in a different hex. Could it be input>hex>ROT>stored, and have a different ROT for each column? The characters within each column appear to stay consistent. Some columns have hex bits that do not represent anything in a normal charset, which is why I think ROT or something similar might be involved.
I've never encountered anything like this, and I'm wondering if anybody here has. Where on the server could the algorithm be stored?
Any help, ideas, or a push in the right direction would be greatly appreciated. |
