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.
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.
