psk
Description:
Pre-Shared-Key for WPA networks.
For WPA-PSK, it's either an ASCII passphrase of 8 to 63 characters that is (as specified in the 802.11i standard) hashed to derive the actual key, or the key in form of 64 hexadecimal character. The WPA3-Personal networks use a passphrase of any length for SAE authentication.
