This folder contains protobuf definitions.

The subfolders (e.g., aes_gcm_go_proto) contain Go auto-generated code of the protobuf definitions. These files facilitate using go get to install the Tink library. This is only applicable outside of google3. To update them, execute the following script:

$ g4d tink
$ ./third_party/tink/tools/

The script performs a Blaze query for the current Go proto dependencies, generates the required files.
