Hi,

 

Used to have a program that I could push stuff like:

 

B6,CA,88,E0,BD,F6,A1,79,70,60,89,6A,EB,6B,CA,BA,A4:

_B7,AD,CB,3A,9D,5B,4A,55,9E,86,08,2A,C7,EE,56,5F,XX

 

 

through to see what it said but I can't remember what it was/was called.

 

Anyone got any ideas?

google "hex editor" there are plenty of free ones

 

I know - but they all return either not recognised or gibberish.....

 

....I used to have a program that would convert it into text but can't remember what it was.

Doesn't it depend on what the hex is being used for? I've got an old IBM EBCDIC card somewhere (showing my age as a former mainframe tech now!) that showed the characters for each hex value... but that would be pretty well useless now, I suspect.

Lordy, when I saw that post I thought I was watching a BBC micro load....

What we've got is a kid who is a bit crafty. He's been caught trying stupid things before so we trawl through all his files every so often to see what he has saved in his user area.

 

There was a Microsoft Word document called 'Work' in a folder called 'Work' which immediately aroused my suspicions, and upon opening it the contents of the document were found to be the:

 

B6,CA,88,E0,BD,F6,A1,79,70,60,89,6A,EB,6B,CA,BA,A4 :

_B7,AD,CB,3A,9D,5B,4A,55,9E,86,08,2A,C7,EE,56,5F,XX

 

which I assume is hex? I think he's hiding something so I need to translate/convert it.

 

Any suggestions?

I used to use xtree's file viewer to view hex files and that'd give a character based 'translation' in the right margin - great for recovering data from corrupt files.

 

 

What about HxD for starters

found this old thread because I thought I'd previously posted something about using HxD; can't find that but found this instead :-)

 

Don't know if you ever found out what he's doing. The stuff you've posted is hex (it's just not the hex of printable ASCII codes - eg 48 65 6C 6C 6F F6 would be Hello).

 

thought it might be hex codes from a bit of machine code; debug lets you type the numbers in and will then show you the matching assembly code but this returns gibberish.

 

what I suspect he's got is a program which reads this and decodes it in some way - either simple substiution (so B6 means A, 79 means B etc) or by doing some maths on it (easiest is XORing each value with some constant because the process is reversible)
