Represents IPv6 authentication header extension (used in IPSec protocol) and allows easy access to all of its data

A c'tor for creating a new IPv6 authentication header extension object not bounded to a packet. Useful for adding new extensions to an IPv6 layer with IPv6Layer::addExtension()
[in] | securityParametersIndex | Security Parameters Index (SPI) value (will be written to ipv6_authentication_header::securityParametersIndex field) |
[in] | sequenceNumber | Sequence number value (will be written to ipv6_authentication_header::sequenceNumber field) |
[in] | integrityCheckValue | A pointer to a buffer containing the integrity check value (ICV) data for this extension. Notice this pointer is read-only and its content isn't modified in any way |
[in] | integrityCheckValueLen | The length of the integrity check value (ICV) buffer |
|
inline |
Get a pointer to the fixed part of the authentication header. Notice the return pointer points directly to the data, so every change will modify the actual packet data

In the authentication header the extension length is calculated in a different way than other extensions. The calculation is: [ 4 * (ipv6_authentication_header::headerLen + 2) ]
Reimplemented from pcpp::IPv6Extension.
