 ### OpenSSL
 
-Google Vision API requires its [JSON Web Token](https://developers.google.com/identity/protocols/OAuth2ServiceAccount) requests to be signed with the [`RSASSA-PKCS1-V1_5-SIGN`](https://www.ietf.org/rfc/rfc3447.txt) algorithm. There were no implementations of that readily available in Lua, and I did not feel like writing one. I simply launch OpenSSL to sign the token request with the private key extracted from the JSON file mentioned above.

 Lightroom will run Lua code either directly as source code, or as a compiled bytecode. The repo contains a compiled distribution package. You can re-build that distribution image with [`rake`](http://rake.rubyforge.org/), even though that is not necessary. Make sure you're running Lua version 5.1, because Lightroom will reject code compiled with newer versions. On Mac OS X, you can install it with [`brew`](https://brew.sh/):
