Struct Dot11WEP 

pub struct Dot11WEP {
    pub offset: usize,
}

WEP (Wired Equivalent Privacy) encryption wrapper.

Format:

[IV (3 bytes)] [KeyID/Pad (1 byte)] [Encrypted Data ...] [ICV (4 bytes)]

The KeyID byte layout:

• Bits 0-5: Pad (reserved, should be 0)
• Bits 6-7: Key ID (0-3)

Fields

offset: usize

Implementations

impl Dot11WEP

pub fn new(offset: usize) -> Self

pub fn validate(buf: &[u8], offset: usize) -> Result<(), FieldError>

Validate buffer length for WEP header.

pub fn iv(&self, buf: &[u8]) -> Result<[u8; 3], FieldError>

Initialization Vector (3 bytes).

pub fn iv_u32(&self, buf: &[u8]) -> Result<u32, FieldError>

Full IV as a u32 (24-bit value, big-endian).

pub fn key_id(&self, buf: &[u8]) -> Result<u8, FieldError>

Key ID (bits 6-7 of byte 3).

pub fn key_id_byte(&self, buf: &[u8]) -> Result<u8, FieldError>

Raw KeyID/Pad byte.

pub fn icv(&self, buf: &[u8], frame_end: usize) -> Result<u32, FieldError>

ICV (Integrity Check Value) — 4 bytes at the end of the encrypted data. frame_end is the offset of the end of the entire frame (after ICV).

pub fn encrypted_data<'a>( &self, buf: &'a [u8], frame_end: usize, ) -> Result<&'a [u8], FieldError>

Encrypted data (between header and ICV).

pub fn header_len(&self) -> usize

Header length (always 4 bytes).

pub fn trailer_len(&self) -> usize

Trailer length (always 4 bytes).

pub fn build_header(iv: [u8; 3], key_id: u8) -> Vec<u8>

Build a WEP header.

pub fn build_icv(icv: u32) -> Vec<u8>

Build a WEP ICV trailer.

Trait Implementations

impl Clone for Dot11WEP

fn clone(&self) -> Dot11WEP

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Dot11WEP

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