Struct SecurityHeader 

pub struct SecurityHeader<'a> { /* private fields */ }

A parsed view over a Security Header in a byte buffer.

The Security Header consists of:

• SPI (16 bits, mandatory)
• Initialization Vector (0-32 bytes, optional)
• Sequence Number (0-8 bytes, optional)
• Pad Length (0-2 bytes, optional)

All field lengths are determined by the Security Association.

Implementations

impl<'a> SecurityHeader<'a>

pub fn parse(sa: &SecurityAssociation, bytes: &'a [u8]) -> Result<Self, Error>

Parse a Security Header from the given bytes using the SA to determine field lengths.

pub fn spi(&self) -> u16

Returns the Security Parameter Index.

pub fn iv(&self) -> &[u8]

Returns the Initialization Vector bytes.

pub fn sequence_number(&self) -> &[u8]

Returns the Sequence Number bytes.

pub fn sequence_number_value(&self) -> u64

Returns the Sequence Number as a u64 value.

pub fn pad_length(&self) -> u16

Returns the Pad Length value.

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
