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. homepage http://acsc.cs.utexas.edu/cpabe/ master_sites ${homepage} checksums sha1 ed94479cde2cc0351487597be477ac7f87242727 \ rmd160 580b9c1550ea097cb89dd2059fd1b11ac964e127 depends_build port:pkgconfig depends_lib port:pbc configure.args --with-pbc-include=${prefix}/include/pbc
