openssl aes-256-cbc -nosalt -in /Volumes/Storage/temp/cryptotest/text.txt -out /Volumes/Storage/temp/cryptotest/encrypted.txt
										^^^^^^^

cf. http://stackoverflow.com/questions/19938470/why-cant-i-decrypt-a-file-with-nodejs-that-i-encrypted-with-openssl

cf. http://stackoverflow.com/a/12378676/893780

NB. NodeJS would appear to have an issue with salts; we should still try to make it work, as it is
considered best practise.
