# Contributor Covenant Code of Conduct
## Our Pledge
In the interest of fostering an open and welcoming environment, we as
contributors and maintainers pledge to making participation in our project and
our community a harassment-free experience for everyone, regardless of age, body
size, disability, ethnicity, gender identity and expression, level of experience,
education, socio-economic status, nationality, personal appearance, race,
religion, or sexual identity and orientation.
## Our Standards
Examples of behavior that contributes to creating a positive environment
include:
* Using welcoming and inclusive language
* Being respectful of differing viewpoints and experiences
* Gracefully accepting constructive criticism
* Focusing on what is best for the community
* Showing empathy towards other community members
Examples of unacceptable behavior by participants include:
* The use of sexualized language or imagery and unwelcome sexual attention or
advances
* Trolling, insulting/derogatory comments, and personal or political attacks
* Public or private harassment
* Publishing others' private information, such as a physical or electronic
address, without explicit permission
* Other conduct which could reasonably be considered inappropriate in a
professional setting
## Our Responsibilities
Project maintainers are responsible for clarifying the standards of acceptable
behavior and are expected to take appropriate and fair corrective action in
response to any instances of unacceptable behavior.
Project maintainers have the right and responsibility to remove, edit, or
reject comments, commits, code, wiki edits, issues, and other contributions
that are not aligned to this Code of Conduct, or to ban temporarily or
permanently any contributor for other behaviors that they deem inappropriate,
threatening, offensive, or harmful.
## Scope
This Code of Conduct applies both within project spaces and in public spaces
when an individual is representing the project or its community. Examples of
representing a project or community include using an official project e-mail
address, posting via an official social media account, or acting as an appointed
representative at an online or offline event. Representation of a project may be
further defined and clarified by project maintainers.
## Enforcement
Instances of abusive, harassing, or otherwise unacceptable behavior may be
reported by contacting the project team at savanni@luminescent-dreams.com. All
complaints will be reviewed and investigated and will result in a response that
is deemed necessary and appropriate to the circumstances. The project team is
obligated to maintain confidentiality with regard to the reporter of an incident.
Further details of specific enforcement policies may be posted separately.
Project maintainers who do not follow or enforce the Code of Conduct in good
faith may face temporary or permanent repercussions as determined by other
members of the project's leadership.
## Attribution
This Code of Conduct is adapted from the [Contributor Covenant][homepage], version 1.4,

# Orizentic
[![CircleCI](https://circleci.com/gh/luminescent-dreams/orizentic/tree/sol.svg?style=svg)](https://circleci.com/gh/luminescent-dreams/orizentic/tree/sol)
[Documentation](https://docs.rs/orizentic")
Orizentic provides a library that streamlines token-based authentication, and a CLI tool for maintaining a database of tokens.
## Credit
The name is a contraction of Auth(oriz)ation/Auth(entic)ation, and credit goes to [Daria Phoebe Brashear](https://github.com/dariaphoebe).
The original idea has been debated online for many years, but the push to make this useful comes from [Aria Stewart](https://github.com/aredridel).
## Tokens
Tokens are simple [JWTs](https://jwt.io/). 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.
## CLI Usage
## Library Usage
[orizentic - Rust](https://docs.rs/orizentic/1.0.0/orizentic/)
There are multiple errata for the documentation:
* There are, in fact, now [two functions](https://docs.rs/orizentic/1.0.0/orizentic/filedb/index.html) for saving and loading a database.
* An example for how to use the library is currently here [for loading the database](https://github.com/luminescent-dreams/fitnesstrax/blob/8c9f3f418ff75675874f7a8e3928ad3f7d134eb4/server/src/web.rs#L64) and here [as part of the AuthMiddleware for an Iron server](https://github.com/luminescent-dreams/fitnesstrax/blob/8c9f3f418ff75675874f7a8e3928ad3f7d134eb4/server/src/server.rs#L156). I apologize for not writing this in more detail yet.
## Language support
This library and application is only supported for Rust. Haskell and Go support has been discontinued, but can be revived if I discover folks have an interest. The token database is compatible across tools. See readmes in the language directory for usage information.
Future Haskell, Go, and other language versions of the library will be done through language bindings against the Rust utilities instead of through my previous clean-room re-implementations.
## Nix installation
If you have Nix installed on your system, or you run NixOS, create this derivation:
orizentic.nix:
```
{ fetchFromGitHub }:
let src = fetchFromGitHub {
owner = "luminescent-dreams";
repo = "orizentic";
rev = "896140f594fe3c106662ffe2550f289bb68bc0cb";
sha256 = "05g7b0jiyy0pv74zf89yikf65vi3jrn1da0maj0k9fxnxb2vv7a4";
};
in import "${src}/default.nix" {}
```
At this time, you must have nixpkgs-19.03 defined (and preferably pointing to the 19.03 channel). I will parameterize this and update the instructions in the future.
I import this into my shell.nix `with import ./orizentic.nix { inherit (pkgs) fetchFromGitHub; };`.
For a complete example, see my [shell.nix](https://github.com/savannidgerinel/nix-shell/blob/sol/shell.nix) file.
I have not bundled this application for any other distribution, but you should nave no trouble just building with just cargo build --release with Rust-1.33 and Cargo.

//! The Orizentic token management library
//!
//! This library provides a high level interface for authentication token management. It wraps
//! around the [JWT](https://jwt.io/) standard using the
//! [`jsonwebtoken`](https://github.com/Keats/jsonwebtoken) library for serialization and
//! validation.
//!
//! Functionality revolves around the relationship between a [ClaimSet](struct.ClaimSet.html), a
//! [VerifiedToken](struct.VerifiedToken.html), and an
//! [UnverifiedToken](struct.UnverifiedToken.html). A [ClaimSet](struct.ClaimSet.html) is
//! considered informative and stores all of the information about the permissions and resources
//! that the token bearer should have access to. [VerifiedToken](struct.VerifiedToken.html) and
//! [UnverifiedToken](struct.UnverifiedToken.html) are the result of the process of decoding a
//! string JWT, and inherently specify whether the decoding process verified the signature,
//! expiration time, and presence in the database.
//!
//! This library does not currently contain database save and load features, but those are a likely
//! upcoming feature.
//!
//! No setup is necessary when using this library to decode JWT strings. Refer to the standalone
//! [decode_text](fn.decode_text.html) function.
