Hi there,

I’m trying to utilise the crypt/rijndael algorithm in rails. I’ve  
written a small script separate from rails that takes a string and  
using a specified key encrypts it and saves it to a file.

I then would like to be able to copy the string in that file and paste  
it into my rails application source and decrypt it using the  
decrypt\_block method of rijndael.

The trouble is the string changes between the file and the pasted text  
in rails. I mean it looks that same but if I puts it out from rails it  
is different. I think this must be a character encoding problem but  
I’m not sure…

Does anyone have any ideas?

Thanks,  
Toby

Sorry should have been more explicit - I’m on OS X and I’m using  
TextMate.

After playing around I’ve found that if I save the file using MacRoman  
as the character encoding it works the way I expected.

Nonetheless I’d like to know a way of doing it even if the file is  
saved in UTF-8.
