We are happy to announce that, from now on, we will create MD5 file hashes for all uploaded and imported files, as well as all encoding result files. This allows you to more easily check for files that have been uploaded to Transloadit already via your platform or check downloaded encoding results for integrity.

There is a new JSON parameter called calc_md5hash, which is now supported by all of our Robot. It is set to false by default. You can activate this functionality by setting the parameter to true.

MD5 is, of course, not very secure, in case you were considering it as means to defend against attackers. That is not the intended purpose, however. We felt MD5's wide availability makes it 'perfect' for integrity checks.

We hope you'll enjoy this change!
