wpa_passphrase: Compute and display the WPA-PSK key for a given SSID reading the passphrase from `stdin`.
$ wpa_passphrase ${SSID}
try on your machine
The command "wpa_passphrase ${SSID}" is used to generate a WPA passphrase or a pre-shared key (PSK) for a wireless network with the given SSID (Service Set Identifier).
Here's how the command works:
- "wpa_passphrase" is the name of the command-line utility used to generate the passphrase.
- "${SSID}" is a placeholder for the SSID of the wireless network. This is the name used to identify the network, usually set by the network administrator or the router settings.
- For example, if the SSID is "MyWiFiNetwork", the command would be written as: wpa_passphrase MyWiFiNetwork
- When you execute the command in the terminal, it prompts you to enter a passphrase (password) for the network.
- After entering the passphrase, it generates a PSK, which is a cryptographic key used for authenticating and encrypting the connection between devices and the wireless network.
- The PSK is typically a long string of characters that is used by devices to connect securely to the network.
