This is being ported from code from rsa-compat.js, greenlock.html (bacme.js), and others.
# Keypairs for node.js
This was intended to be just a weekend project, but it's grown a bit.
Lightweight JavaScript RSA and ECDSA utils that work on Windows, Mac, and Linux
using modern node.js APIs (no need for C compiler).
* 2018-10-10 (Saturday) work has begun
* 2018-10-11 (Sunday) W00T! got a CSR generated for RSA with VanillaJS ArrayBuffer
* 2018-10-12 (Monday) Figuring out ECDSA CSRs right now
* 2018-10-15 (Thursday) ECDSA is a trixy hobbit... but I think I've got it...
* 2018-12-02 (Sunday) Been mostly done for a while, individually, slowly merging everything together
* [Rasha.js](https://git.coolaj86.com/coolaj86/rasha.js) (RSA utils)
* [Eckles.js](https://git.coolaj86.com/coolaj86/eckles.js) (EC utils)
A thin wrapper around [Eckles.js (ECDSA)](https://git.coolaj86.com/coolaj86/eckles.js/)
and [Rasha.js (RSA)](https://git.coolaj86.com/coolaj86/rasha.js/).
# Features
* [x] Generate keypairs
* [x] RSA
* [x] ECDSA (P-256, P-384)
* [x] PEM-to-JWK
* [x] JWK-to-PEM
* [x] SHA256 JWK Thumbprints
* [ ] JWK fetching. See [Keyfetch.js](https://npmjs.com/packages/keyfetch/)
* [ ] OIDC
* [ ] Auth0
<!--
Keypairs&trade; for node.js
===========================
JavaScript RSA and ECDSA utils that work on Windows, Mac, and Linux with or without C compiler.
* [ ] sign JWS
* [ ] generate CSR (DER as PEM or base64url)
There are many different RSA and ECDSA libraries for node and it seems like they're
all incompatible in different ways. This isn't [yet another library](https://xkcd.com/927/),
but rather [one to rule them all and bind them](https://en.wikipedia.org/wiki/One_Ring).
-->
Features
========
# Usage
* [x] RSA
* [ ] ECDSA (in-progress)
* [x] generate keypair
* [x] export to JWK
* [x] import from JWK
* [x] export to PEM
* [x] import from PEM
* [x] sign JWS
* [x] generate CSR (DER as PEM or base64url)
A brief (albeit somewhat nonsensical) introduction to the APIs:
API
===
```
Keypairs.generate().then(function (jwk) {
return Keypairs.export({ jwk: jwk }).then(function (pem) {
return Keypairs.import({ pem: pem }).then(function (jwk) {
return Keypairs.thumbprint({ jwk: jwk }).then(function (thumb) {
console.log(thumb);
});
});
});
});
```
By default ECDSA keys will be used since they've had native support in node
_much_ longer than RSA has, and they're smaller, and faster to generate.
## API
Each of these return a Promise.
* `Keypairs.generate(options)`
* options example `{ type: 'RSA' || 'ECDSA', bitlength: 2048 || 256 }`
* options example `{ kty: 'RSA', modulusLength: 2048 }`
* options example `{ kty: 'ECDSA', namedCurve: 'P-256' }`
* `Keypairs.import(options)`
* options example `{ pem: '...', crv: 'P-256' || 'ECC', bitlength: 2048 || 256 }`
* options example `{ pem: '...' }`
* `Keypairs.export(options)`
* options example `{ private: true || false, pem: true || false }`
* options example `{ jwk: jwk }`
* options example `{ jwk: jwk, public: true }`
* `Keypairs.thumbprint({ jwk: jwk })`
<!--
* `Keypairs.jws.sign(options)`
* options example `{ keypair, header, protected, payload }`
* `Keypairs.csr.generate(options)`
* options example `{ keypair, [ 'example.com' ] }`
`keypair` can be any object with
any of these keys `publicKeyPem, privateKeyPem, publicKeyJwk, privateKeyJwk`.
Examples
========
These are quick examples of how to use the library.
If you have a specific question, please open an issue.
Keypairs.generate(options)
-------------------
Simple RSA
```js
return Keypairs.generate({
type: 'RSA'
, bitlength: 2048
}).then(function (keypair) {
// we won't bother describing this object
// because it's only useful once exported
});
```
Advanced RSA
```js
return Keypairs.generate({
type: 'RSA'
, bitlength: 2048 // or 4096
, exponent: 65537 // don't change this
, public: true // pre-cache public key
, pem: true // pre-export the PEM
, internal: true // pre-cache internal representations
}).then(function (keypair) {
// we won't bother describing this object
// because it's only useful once exported
});
```
Keypairs.export(options)
-------------------
Keypairs.import(options)
-------------------
Keypairs.jws.sign(options)
-------------------
Keypairs.csr.generate(options)
-------------------

# Full Documentation
Keypairs.js provides a 1-to-1 mapping to the Rasha.js and Eckles.js APIs.
The full RSA documentation is at [Rasha.js](https://git.coolaj86.com/coolaj86/rasha.js/)
The full ECDSA documentation is at [Eckles.js](https://git.coolaj86.com/coolaj86/eckles.js/)
Any option you pass to Keypairs will be passed directly to the corresponding API
of either Rasha or Eckles.
