Add CRTTool for SSL Certificate Analysis

[darielnoel]

Is your feature request related to a problem? Please describe.
Currently, KaibanJS does not include a tool for analyzing SSL certificates, which can be useful for security-related workflows. This feature could enhance agent capabilities in domains such as security and compliance by enabling SSL analysis directly within workflows.

Describe the solution you'd like
I propose adding the CRTTool, a utility that fetches SSL certificate data from crt.sh via a CORS proxy. This tool will enable agents to analyze SSL certificates for a specified domain, providing insights into subdomains, certificate issuers, validity periods, and potential risks. The tool would integrate seamlessly with the KaibanJS framework, as demonstrated in the provided example code.

Describe alternatives you've considered

• Manually fetching and parsing SSL certificate data outside KaibanJS workflows, which adds unnecessary complexity.
• Using third-party tools for SSL analysis, which lacks direct integration with agents in KaibanJS.

Additional context
The CRTTool is designed to fetch and parse JSON data of SSL certificates from crt.sh using the axios library and the allorigins.win proxy. Here is the implementation:

import { Tool } from "@langchain/core/tools";
import { z } from "zod";
import axios from "axios";

export class CRTTool extends Tool {
  constructor(fields) {
    super(fields);
    this.name = "crt_tool";
    this.description = "Fetches JSON data of certificates from crt.sh for a given domain using a CORS proxy.";
    this.schema = z.object({
      domain: z
        .string()
        .describe("The domain to fetch certificate JSON data for."),
    });
  }

  async _call(input) {
    try {
      const requestUrl = `https://api.allorigins.win/raw?url=${encodeURIComponent(
        `https://crt.sh/json?q=${input.domain}`
      )}`;
      const response = await axios.get(requestUrl);

      const data = response.data;
      if (typeof data === 'string') {
        return JSON.parse(data); // Ensure string JSON is parsed
      }
      return data;
    } catch (error) {
      return `Error fetching JSON data from crt.sh: ${error.message}`;
    }
  }
}

Additionally, this feature integrates into a sample agent and task:

• Agent: SSL Certificate Analyzer
• Task: Analyze SSL certificates and generate security reports.
