This is a command-line tool that can encrypt and decrypt small files with AES128-GCM.
It demonstrates the basic steps of using Tink, namely generating or loading key material, obtaining a primitive, and using the primitive to do crypto.
It also shows how to add a dependency on Tink using Maven. Please checkout the pom.xml file.
