Rails - Dec 2005 - Encrypting files

Anyone know of a good (fast) way to encrypt/decrypt uploaded files in 
RoR?  I''ve seen this project: http://ezcrypto.rubyforge.org/  but it 
only seems to encrypt strings and such.  I need to encrypt files once 
they are uploaded, then decrypt them when they request the file back.

Any ideas?

Thanks,

Mark

	If you want to do this one way I can think of is the use the  
ezcrypto lib you found and with a few other steps you could make it  
work. What you could do is once the file is uploaded, read it into a  
string and Base64 encode it before it goes in the db or on the  
filesystem. Then when it comes time to send the file down to a user  
again, you can read it in and unencode it form base64 and then  
decrypt it and use send_file or send_data to get it to the browser.

	There might be a much better way to do this with less overhead but  
this is one way.

OpenSSL is in the Ruby standard library.  Here''s a blog with some
sample usage:  http://weblog.masukomi.org/index.pl/view/encryption%20in%20ruby
