 # libsodium23
 
+Sodium is a new, easy-to-use software library for encryption, decryption, signatures, password hashing and more.
+It 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.
