Password Security Tips

  • Use a minimum of 12 characters, more if possible
  • Include a mix of uppercase, lowercase, numbers, and symbols
  • Avoid using personal information like names, birthdates, or common words
  • Use different passwords for different accounts
  • Consider using a password manager to store your passwords securely

About These Tools

These interactive tools are designed for educational purposes to help you understand the principles of cryptography and encryption. They demonstrate various techniques used in securing digital information.

While these tools implement real cryptographic algorithms, they are running in your browser and should not be used for securing sensitive information in production environments. For real-world security applications, use established cryptographic libraries and frameworks.
