Hey, thanks for the pull request. Unfortunately the travis build has failed, due to a gem install error... can you take care of that?

Also, did you investigate why the new openssl is asking for 16 bytes instead of 32? Was it truncating to 16 bytes anyway previously?

Thanks.

Hello I just fixed the pull request and to answer your questions yes it was previously working on ruby version 2.3.4 but I upgraded mid project and noticed it errors out on ruby version 2.4 even using your README's example

and I just found this on another projects github(attr-encrypted/encryptor#26) issue which pointed me to the change in openssl(ruby/ruby@ce63526)

Is this going to get merged? I'm still seeing the "key must be 16 bytes" error when encrypting with dir.

Sadly @lizGraham9CB this pull request would not stop you from seeing that error message. This pull request that I did over a year ago basically changes the readme to use 16 bytes in the example and adds a test case to show that it errors out on anything later than ruby 2.4 with a byte size greater than 16. I believe it is not specific to this gem and has to do with OpenSSL. The links I provided in my previous message give some good examples to try to work around this issue.
