I would probably try a for loop and see if you get a 'TRUE' from the IsTime() function (since that is what I can see is a time in the data.
local numbervar iCount :=0;
do while Not isTime(mid({table.field}, iCount + 1)) and iCount < Len({table.field})
iCount := iCount + 1;
iCount <> Len({table.field})
this formula will return True if the data is valid, false if encrypted.
Without knowing the encryption method and key, the odds of deciphering the data is pretty slim. If you knew what it equated to, it might be possible, otherwise it is just the jibberish you see.
the syntax might be off (I don't use loops too often) so I would double check with the Help files in Crystal.
