-A [Root](https://therootcompany.com) Project.
+Sponsored by [Root](https://therootcompany.com).
 Built for [ACME.js](https://git.coolaj86.com/coolaj86/acme.js)

-RSA tools. Lightweight. Zero Dependencies. Universal compatibility.
-
-* [x] Fast and Easy RSA Key Generation
 * [x] PEM-to-JWK
 * [x] JWK-to-PEM
-* [x] JWK thumbprint
 * [x] SSH "pub" format
-* [ ] ECDSA
-  * **Need EC or ECDSA tools?** Check out [Eckles.js](https://git.coolaj86.com/coolaj86/eckles.js)
 
+This project is fully functional and tested (and the code is pretty clean).
 
-## Generate RSA Key
+It is considered to be complete, but if you find a bug please open an issue.
 
-Achieves the *fastest possible key generation* using node's native RSA bindings to OpenSSL,
+## Looking for ECDSA as well?
-then converts to JWK for ease-of-use.
 
-```
+Check out [Eckles.js](https://git.coolaj86.com/coolaj86/eckles.js)
-Rasha.generate({ format: 'jwk' }).then(function (keypair) {
-  console.log(keypair.private);
-  console.log(keypair.public);
-});
-```
-
-**options**
-
-* `format` defaults to `'jwk'`
-  * `'pkcs1'` (traditional)
-  * `'pkcs8'` <!-- * `'ssh'` -->
-* `modulusLength` defaults to 2048 (must not be lower)
-  * generally you shouldn't pick a larger key size - they're slow
-  * **2048** is more than sufficient
-  * 3072 is way, way overkill and takes a few seconds to generate
-  * 4096 can take about a minute to generate and is just plain wasteful
-
-**advanced options**
-
-These options are provided for debugging and should not be used.
-
-* `publicExponent` defaults to 65537 (`0x10001`)
 
 ## PEM-to-JWK
 
 * [x] PKCS#1 (traditional)
 * [x] PKCS#8, SPKI/PKIX
-* [x] 2048-bit, 3072-bit, 4096-bit (and ostensibily all others)
+* [x] 2048-bit, 4096-bit (and ostensibily all others)
