Examples of using X509Crl and X509CrlGenerator

[dangtony98]

Foremost, thank you for this great library!

As part of needing to implement various CRL functionality, I noticed related PRs merged here and here but couldn't find any examples in the repo of using these structures.

I wonder if it'd be possible for you to provide some minimal example of usingX509CrlEntry, X509CrlGenerator, and any related structures; this would be extremely helpful (something similar to the example showed here should be great).

Note that upon trying to create a minimal instance of X509CrlEntry with the following:

const serialNumber = crypto.randomBytes(16).toString("hex");
const crlEntry = new x509.X509CrlEntry(serialNumber, new Date(), []);

as per the constructor:

constructor(serialNumber: string, revocationDate: Date, extensions: Extension[]);

I'm getting the following error:

dev-api              |     }

Overall, it would be great to get a concrete example of how to use the structure.

Nevermind. I was able to reference an example in one of the tests:

const crl = await x509.X509CrlGenerator.create({
      // issuer: caCert.issuer,
      issuer: "Test",
      thisUpdate: new Date("2022/01/01"),
      nextUpdate: new Date("2022/12/12"),
      entries: [
        {
          serialNumber: "01",
          revocationDate: new Date("2022/01/01"),
          reason: x509.X509CrlReason.certificateHold,
          invalidity: new Date("2022/01/01"),
          issuer: "CN=Test, O=Дом"
        }
      ],
      signingAlgorithm: alg,
      signingKey: sk
    });

This seems to work.
