An implimentation of tweetnacl in pure rust. Originally generated by manually translating tweetnacl.c into rust. Tested by verifying outputs match those of tweetnacl.


  • provide additional APIs:
    • rather than take bare mutable references, use wrapper types around the refs to capture the underlying type (ie: prevent mixing keys between primitives)
    • add a buffer and/or "set-only" abstraction to prevent unsafety wrt uninitialized values (also should allow some internal optimization).
    • sodiumoxide style API that returns values rather than taking mutable refs
  • Use namespacing to seperate different APIs and backend impls
  • start testing against sodiumoxide as well
  • Provide some of the API impovements from libsodium that are missing nacl (disjoint signatures, not requiring special extra space in buffers)
