Which of the following is an example of secure encryption?

WPA2 and WPA3 protocols are designed to provide secure encryption for wireless communications. They utilize advanced encryption techniques to safeguard data being transmitted over a wireless network, thus ensuring that the information is protected from eavesdropping and unauthorized access. By using strong encryption standards, these protocols help to maintain the confidentiality and integrity of data as it travels through potentially vulnerable wireless environments.

In contrast, default passwords, plain text passwords, and unencrypted data storage lack the necessary security measures to protect sensitive information effectively. Default passwords can easily be exploited if not changed, plain text passwords are visible to anyone who can access the transmission, and unencrypted data storage does not provide any protection against unauthorized access. Therefore, the use of WPA2 or WPA3 represents a secure method of encryption compared to the other options, which do not incorporate any form of encryption to protect data.
