For example, we can encrypt a ciphertext such that in a company it can only be decrypted by a someone with attributes Senior and Human Resources or has the attribute Executive. One interesting application of this tool is that we can do Role-Based Access Control (RBAC) without requiring trusted data storage.","active":true,"categories":["security"],"maintainers":[],"variants":["universal"],"dependencies":[{"type":"build","ports":["pkgconfig","clang-9.0"]},{"type":"lib","ports":["openssl","gettext","pbc","libbswabe","glib2"]}],"depends_on":[]}
