This is being ported from code from rsa-compat.js, greenlock.html (bacme.js), and others.
|
||||
|
||||
This is my project for the weekend. I expect to be finished today (Monday Nov 12th, 2018)
|
||||
This was intended to be just a weekend project, but it's grown a bit.
|
||||
|
||||
* 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)
