I have a web page here: [url removed, login to view] that can be used to help people construct the command line to generate a certificate request.
I want this page updated so that you can feed it a certificate request and it can re-construct what command line would have produced that certificate request.
The decoding can be implemented on top of [url removed, login to view]
The class would look something like:
.Extensions = (array of ID, Value)
.Attributes = (array of ID, Value)
It will be able to decode the following extensions:
Extended Key Usage
This will be useful resource: [url removed, login to view] as it does the leg work to define where the data elements are in the ASN.1.
To keep code re-usable, and readable constants and functions that this PKCS10 class uses from other standards will be in a dependency ([url removed, login to view]) like was done here: [url removed, login to view]
I also want the website updated to support adding additional organization units (OUs) and various subject alternative names as was done in this website:
[url removed, login to view]
The addition of subject alternative names requires the creation of a configuration file as was done in one of the current examples on [url removed, login to view]; this creation of a configuration file adds complexity so I only want it created when options are chosen by the user that require the creation configuration file.
I want an advanced option added to the page that is hidden under a UI affordance of some sort that allows the user to paste a Base64 CSR into it, that field will use [url removed, login to view] to validate the request has the appropriate PEM armor for a certificate request:
"^-----(BEGIN|END) (|NEW )CERTIFICATE REQUEST-----$")
It would be nice if it also used: [url removed, login to view] for this.
A valid CSR being present will be all that is necessary to do the decode (aka no button).
Depending on your assessment of complexity after completion I also would like to add verifying the signature done based on web crypto using a polyfill (such as this one [url removed, login to view]) as well as generating keys and signing the resulting keys using the same poly fill.
See: [url removed, login to view] for an idea of what signature verification might look like in the UI (this is done server side)
And see [url removed, login to view] for example of key generation and signing might look like.
I have lots of future work for the right candidate.
