Detailed Description

Represents an IPSec Authentication Header.

Constructor & Destructor Documentation

◆ IPSecESP()

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

Constructs an IPSecESP 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 IPSecESP header, a malformed_packet exception is thrown.

Parameters
bufferThe buffer from which this PDU will be constructed.
total_szThe total size of the buffer.

Member Function Documentation
