Struct vodozemac::ecies::CheckCode

source ·
pub struct CheckCode { /* private fields */ }
Expand description

A check code that can be used to confirm that two EstablishedEcies objects share the same secret. This is supposed to be shared out-of-band to protect against active MITM attacks.

Since the initiator device can always tell whether a MITM attack is in progress after channel establishment, this code technically carries only a single bit of information, representing whether the initiator has determined that the channel is “secure” or “not secure”.

However, given this will need to be interactively confirmed by the user, there is risk that the user would confirm the dialogue without paying attention to its content. By expanding this single bit into a deterministic two-digit check code, the user is forced to pay more attention by having to enter it instead of just clicking through a dialogue.

Implementations§

source§

impl CheckCode

source

pub const fn as_bytes(&self) -> &[u8; 2]

Convert the check code to an array of two bytes.

The bytes can be converted to a more user-friendly representation. The CheckCode::to_digit converts the bytes to a two-digit number.

source

pub const fn to_digit(&self) -> u8

Convert the check code to two base-10 numbers.

The number should be displayed with a leading 0 in case the first digit is a 0.

§Examples
let check_code = check_code.to_digit();

println!("The check code of the IECS channel is: {check_code:02}");
