Hi,
We need some help in how to prevent password replay attack in . Net and also in how to prevent passing of encryption key along with encrypted password.
Please advise.
Thanks and Regards,

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 time-based 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.

Use salted hashing algorithms like bcrypt or PBKDF2 to store passwords securely. Implement secure session management techniques, including session tokens with expiration times and secure session storage. Employ SSL/TLS encryption to protect data during transmission. Implement strong authentication mechanisms like multi-factor authentication. Safeguard encryption keys separately from passwords, utilizing key management systems or hardware security modules. Protect against brute-force attacks with account lockout policies and rate limiting. Keep your .NET framework and libraries up to date with regular updates and patches.
