Subject: Smoking hash-ish: Letter mapping...

Hi,

 for a *very* simplistic encryption program I want to build a 
 hash, which should be dynamically build (not hardcoded).

 The input of the method which should do the job will be a range of
 any meaningful input, say: parameter 1: A and parameter 2: Z

 Then the method should create a Hash with that mapping
 "A" -> "Z"
 "B" -> "G"
 "C" -> "T"
 ...

 or in other words:
 The key should follow the given range, and the values should
 represent all values of that range but in random order.

 For arrays I learned a nice trick from this list:

	 encmap=(A..Z).to_a.sort{rand(2)}

 but...how can I accomplish similiar for a hash ???

 And: I sthere a simple way to store a hash in binary format and later
 load that hash again into memory ?

 Nice weekend!
