A higher level abstraction of https://github.com/jedisct1/libsodium.js:[libsodium.js], written in TypeScript.

== Usage

The functions and their associated types are pretty self-explanatory. See the table below for available functions, and ./lib.ts for details.

Any output that may be binary and input that must be binary is converted to and is required to be a https://npmjs.com/package/buffer[Buffer]. Use buf.toString('hex' | 'base64') to turn it into an encoded string, or buf.toString() if you are sure it's a human readable string.
