Features

General

  • Ability to use commercially under the terms of the MPLv2.
  • Great collaborative documentation.

  • Bundled and compiled native libraries so you don't have to.
  • Reactive and fast release cadence.
  • Bring your own Libsodium native libraries.
  • Lazysodium for Android and Lazysodium for Java both benefit from the same codebase.
  • They both have been designed with JNA Direct Mapping for extra speed.

  • Architected in such a way that you can use the raw JNA wrapped native C functions whenever you want.
