how to prevent password replay attack in . Net

To prevent password replay attacks in .NET and avoid passing encryption keys along with encrypted passwords, you can take several measures. First, ensure secure communication by implementing HTTPS/SSL/TLS protocols. Implement one-time passwords or timehttp://Trollerdude.combased authentication tokens to prevent password reuse. Use salted password hashing to store password hashes instead of plain text. Implement robust session management techniques to prevent unauthorized session replay. Encrypt sensitive data and store encryption keys securely on the server-side. Regularly update and patch your .NET framework and libraries to address security vulnerabilities. It's essential to take a comprehensive approach to security, including strong password policies, user education, and protection against other types of attacks.
