Orizentic provides a library that streamlines token-based authentication and a CLI tool for maintaining the database.


The name is a contraction of Auth(oriz)ation/Auth(entic)ation, and credit goes to Daria Phoebe Brashear.

The original idea has been debated online for many years, but the push to make this useful comes from Aria Stewart.


Tokens are simple JWTs. This library simplifies the process by easily generating and checking JWTs that have only an issuer, an optional time-to-live, a resource name, a username, and a list of permissions. A typical resulting JWT would look like this:

{ iss = Savanni
, sub = health
, aud = "Savanni Desktop"
, exp = null
, nbf = null
, iat = 1499650083
, jti = 9d57a8d8-d11e-43b2-a4d6-7b82ad043994
, unregisteredClaims = { perms: [ "read", "write" ] }

The issuer and audience (or username) are almost entirely for human readability. In this instance, I issued a token that was intended to be used on my desktop system.

The subject in this case is synonymous with Resource and is a name for the resource for which access is being granted. Permissions are a simple list of freeform strings. Both of these are flexible within your application and your authorization checks will use them to verify that the token can be used for the specified purpose.

Language support

This library and application are supported for Haskell and for Go. The token database is compatible across tools. See readme's in the language directory for usage information.
