 # ca-certificates-brazil
 The Brazilian Public Key Infrastructure:  ICP-Brasil
+
+## Description
+The Brazilian Public Key Infrastructure - ICP-Brasil is a hierarchical chain
+of trust that enables the issuance of digital certificates for the virtual
+identification of citizens.
+
+It is observed that the model adopted by Brazil was single-root certification,
+and the ITI, in addition to playing the role of Root Certifying Authority - Root AC,
+also has the role of accrediting and discrediting the other participants in the
+chain, supervise and audit the processes.
