Read binary file as string in Ruby

Question

I need an easy way to take a tar file and convert it into a string (and vice versa). Is there a way to do this in Ruby? My best attempt was this:

file = File         


        

Answer 1

You can probably encode the tar file in Base64. Base 64 will give you a pure ASCII representation of the file that you can store in a plain text file. Then you can retrieve the tar file by decoding the text back.

You do something like:

require 'base64'

file_contents = Base64.encode64(tar_file_data)

Have look at the Base64 Rubydocs to get a better idea.
