    Trying to decode a message. . .

    Hey, I have a quick question. A friend of mine has challenged me to decode a message he found somewhere. It's not really a big deal if it can't be done, but I do want to impress him.

    The message looks like it simply needs to be converted from Hex to Ascii.

    Here is an excerpt of the data:

    BE2001BF2001B92010AD357FC5AB4975
    F8B80109BA2001CD21C3909090909090

    1CB113BC5FB00FE508AC0BAD5FB117A0
    5FB116A81AB645E536E514A01AB55FA4
    11BC0BAD16AB18E509A413B01AA41DA9
    1AE510AB5FA806E510B211E50FA00DB6
    10AB5FED0EB016B11AE50CB51AA616A3
    16A61EA913BC5FAA11E512BC5FAE1ABC
    5FAD10A91BA00DEC53E51BAC18AC0BA4

    [...]

    The first thing I did was convert the message to ASCII, but all I got was a whole bunch of junk.
    Obviously some type of encryption is at work here. My question is: how would you go about further decoding a "random" message like this? Would you remove every X characters or MOD every value by a magic number?
    Do you know of any good resources that would show how to decode this?I want to try to do it myself if possible.
    Or is there a program that does it all for you?
    Custom system: Needs upgrading. Bad.

    The first thing I'd do is to decode using mainframe character codes such as EBCDIC and ECMA. I'm sure that NSA can decode the message in a nanosecond.
