Types for which are able to perform header cryptography.

Required Methods

fn opening_header_protection_mask(
    &self,
    ciphertext_sample: &[u8]
) -> HeaderProtectionMask

Derives a header protection mask from a sample buffer, to be used for opening a packet.

The sample size is determined by the key function.

fn opening_sample_len(&self) -> usize

Returns the sample size needed for the header protection buffer

fn sealing_header_protection_mask(
    &self,
    ciphertext_sample: &[u8]
) -> HeaderProtectionMask

Derives a header protection mask from a sample buffer, to be used for sealing a packet.

The sample size is determined by the key function.

fn sealing_sample_len(&self) -> usize

Returns the sample size needed for the header protection buffer
