+SUMMARY="A modern, easy-to-use software library for cryptographic standards"
+DESCRIPTION="Sodium is a portable, cross-compilable, installable, packageable \
+fork of NaCl, with a compatible API, and an extended API to improve usability \
+even further.
+Its goal is to provide all of the core operations needed to build higher-level \
+cryptographic tools.
+The design choices emphasize security, and \"magic constants\" have clear rationales.
+Despite the emphasis on high security, primitives are faster across-the-board \
+than most implementations of the NIST standards."
