Does Wireshark Capture Passwords?

Wireshark is a popular network protocol analyzer that allows users to analyze network traffic in real time. One common question that arises among users is whether Wireshark can capture passwords.

The short answer is yes, Wireshark can capture passwords if they are transmitted over an unencrypted network protocol such as HTTP or FTP. When packets containing login credentials pass through a network that is being monitored by Wireshark, the tool can display these credentials in plain text.

However, if passwords are transmitted over an encrypted connection using protocols like HTTPS (SSL/TLS) or SSH, Wireshark will not be able to capture the actual password. Instead, it will display the encrypted data, making it much harder to decipher without the encryption keys.

It is important to note that capturing passwords using Wireshark without the consent of the parties involved is illegal and unethical. It is crucial to always respect privacy and abide by laws and regulations when monitoring network traffic.

In conclusion, while Wireshark can capture passwords under certain conditions, it is essential to use encryption protocols to ensure that sensitive information remains secure during transmission.
