    Hey all, it's been a real long time since I have been here but I just got one of those "Hey what happened to you" emails, so here I am.

    Anyways, I have what I presume to be a text file on my mac, with the extension of .msmprof, custom as far as I can tell. When I open it it looks like this:

    Code:
    «ƒHgãÿ⁄q˙⁄÷d(ûL/u1u˘)j΄!òj%◊âÒÃsy|6Yãı!÷€dKƒòŒ1'
    I was wondering if there was a way to tell what sort of encryption it is in and possibly decrypt it. I would like to know what it is. Thanks!

    Hello again, Nick.

    It's not encrypted, it's binary data. When you open binary data in a text editor, it looks like gook because the 0's and 1's that make up the file aren't supposed to be grouped into bytes and assumed to represent characters.

    Here's what my forum avatar looks like in a text editor. Look familiar? It's not encrypted text, it's binary data.



    You have a series of 0's and 1's. You can't find out what they mean without context any more than you can decode a pile of sand.

    Oh, ok. So there is no human readable format I can view it in?
