Let’s not forget C#:
File.WriteAllText(“output.txt”, Convert.ToBase64String(File.ReadAllBytes(“input.pdf”)));

Couldn’t resist…
Ruby script:
require “base64″
File.open(ARGV[0], ‘r’) do |input|
File.open(ARGV[1], ‘w’) do |output|
output.write(Base64.b64encode(input.read))
end
end
Ruby command line:
ruby -e ‘print [IO.read(File.join(Dir.pwd, ARGV[0]))].pack(“m”)’ input.pdf > output.txt
No luck on the LOLcode…

Thanks Matt! Good stuff.
I think the only language from the Arc90 family that we’re missing at this point is Ruby… I wonder how long it’ll be before Nir or Dan post up a Ruby script for this purpose. And what’s after that? LOLcode?

Wow, don’t post while distracted by the television, kids :P
One more try…
file_put_contents(
$argv[2],
base64_encode(file_get_contents($argv[1]))
);

Apparently, php tags cause all following text to be stripped…
file_put_contents(
$argv[2],
file_get_contents($argv[1])
);

Python and Groovy are nice, but for “in the next few minutes”, don’t forget your resident php devs!

Good tip Chris! Thanks!
It’s also possible to run Python and Groovy scripts directly from the command line:
python -c “import binascii;open(‘output.txt’, ‘w’).write(binascii.b2a_base64(open(‘documents.pdf’).read()))”
groovy -e ‘new File(“output.txt”).write(new File(“documents.pdf”).readBytes().encodeBase64().toString())’

This little terminal one liner to encode/decode is also pretty neat:

openssl also supports a lot of different encodings/digests (man dgst and man enc for more)
