Detailed Description

Represents an IPSec Authentication Header.

Constructor & Destructor Documentation

Tins::IPSecAH::IPSecAH ( )

Default constructor.

The ICV field is initialized with four 0 bytes. The length field is initialized appropriately.

Tins::IPSecAH::IPSecAH	(	const uint8_t *	buffer,
		uint32_t	total_sz
	)

Constructs an IPSecAH object from a buffer and adds all identifiable PDUs found in the buffer as children of this one.

If there is not enough size for an IPSecAH header, a malformed_packet exception is thrown.

Parameters

buffer	The buffer from which this PDU will be constructed.
total_sz	The total size of the buffer.
