Member Function Documentation

void Tins::Crypto::WEPDecrypter::add_password	(	const address_type &	addr,
		const std::string &	password
	)

Adds a decryption password.

Parameters

addr	The access point's BSSID.
password	The password which will be used to decrypt packets sent from and to the AP identifier by the BSSID addr.

bool Tins::Crypto::WEPDecrypter::decrypt

(

PDU &

pdu

)

Decrypts the provided PDU.

A Dot11Data PDU is looked up inside the provided PDU chain. If no such PDU exists or there is no password associated with the Dot11 packet's BSSID, then the PDU is left intact.

Otherwise, the packet is decrypted using the given password. If the CRC found after decrypting is invalid, false is returned.

Returns

false if no decryption was performed or decryption failed, true otherwise.

void Tins::Crypto::WEPDecrypter::remove_password

(

const address_type &

addr

)

Removes a decryption password.

Parameters

addr	The BSSID of the access point.
