Markdown Features Showcase

This post demonstrates all the markdown features available for writing blog posts.

Headings

You can use different heading levels to organize your content.

Third Level Heading

Use these for subsections within your main sections.

Text Formatting

You can make text bold for emphasis or use italics for subtle emphasis. You can also combine both if needed.

Links

Here's a link to example.com that you can click.

Lists

Unordered Lists

• First item in the list
• Second item with more details
• Third item to complete the set
• Nested concepts work great here

Ordered Lists

1. First step in the process
2. Second step follows naturally
3. Third step wraps things up

Blockquotes

Security is not a product, but a process. It's more than designing strong cryptography into a system; it's designing the entire system such that all security measures, including cryptography, work together.

— Bruce Schneier

Images

You can embed images using markdown syntax:

Images can also have alt text for accessibility, which describes the content for screen readers.

Code

Inline code looks like this: const x = 42; or npm install.

Code Blocks

Here's a plain code block without a language specified:

[2026-01-15 14:32:01] INFO: Starting security scan...
[2026-01-15 14:32:02] WARN: Port 22 open - SSH detected
[2026-01-15 14:32:03] INFO: Checking SSL/TLS configuration
[2026-01-15 14:32:05] ERROR: Certificate expires in 7 days
[2026-01-15 14:32:06] INFO: Scan complete. 2 issues found.

Here's a JavaScript example:

function analyzeVulnerability(target) {
  const results = {
    timestamp: Date.now(),
    findings: []
  };
  
  // Perform security analysis
  for (const check of securityChecks) {
    const finding = check.run(target);
    if (finding.severity > 0) {
      results.findings.push(finding);
    }
  }
  
  return results;
}

Python code with syntax highlighting:

import hashlib
from typing import Optional

def verify_hash(data: bytes, expected: str) -> bool:
    """Verify data integrity using SHA-256."""
    computed = hashlib.sha256(data).hexdigest()
    return computed == expected

class SecurityScanner:
    def __init__(self, target: str):
        self.target = target
        self.vulnerabilities: list = []
    
    def scan(self) -> Optional[dict]:
        # Implementation here
        pass

Shell commands:

# Clone the repository
git clone https://github.com/example/security-toolkit.git

# Install dependencies
cd security-toolkit
pip install -r requirements.txt

# Run the scanner
python -m scanner --target example.com

Combining Elements

Here's a practical example combining multiple features:

Note: When performing security research, always ensure you have proper authorization. Unauthorized testing is illegal and unethical.

Key considerations:

1. Scope - Define clear boundaries
2. Documentation - Record all findings
3. Disclosure - Follow responsible disclosure practices

For more information, check out the --help flag or visit the documentation.

Footnotes

Footnotes allow you to add references without cluttering the main text¹. They're great for citations² or additional context.

You can also use descriptive footnote labels³ for better organization.

Conclusion

This showcase covers the core markdown features. Use them to create clear, well-structured blog posts that effectively communicate your security research and findings.
