RFC822 Email Validator

A simple, offline Python tool for validating email addresses against the RFC822 standard. Perfect for quick checks, integration into scripts, or security testing of email input fields.

Features

• RFC822-compliant: Uses a regular expression closely matching the RFC822 specification.
• Offline: No network connection required.
• Easy to use: Just run the script and enter an email address.
• Security Testing: Useful for testing input validation, including XSS payloads.

Usage

1. Clone the repository or download the script: git https://github.com/coffinxp/RFC822-Email-Validator.git) cd RFC822-Email-Validator

2. Run the script: python3 rfc822_email_validator.py

3. Enter the email address you want to validate when prompted.

4. Result: The script will print "RFC822 valid: YES" if the email is valid, or "RFC822 valid: NO" if not.

Example

$ python3 rfc822_email_validator.py Enter email address: test@example.com RFC822 valid: YES

$ python3 rfc822_email_validator.py Enter email address: ">@test.com RFC822 valid: NO

Security Testing

You can use this tool to test how your application handles potentially malicious email input, such as XSS payloads. Example payloads to try: - ">@test.com - ">@test.com - ">"@x.y

Requirements

• Python 3.x

Inspired by the classic RFC822 email validation tools and designed for modern security testing workflows.
