Struct PcrState 

pub struct PcrState { /* private fields */ }

State of PCR registers

Implementations

impl PcrState

pub fn new() -> Self

Create a new PCR state with all registers zeroed

pub fn extend( &mut self, pcr_index: usize, digest: &[u8; 32], ) -> Result<[u8; 32], BootVerifyError>

Extend a PCR with a new digest: PCR[i] = SHA256(PCR[i] || digest)

Returns the new PCR value or an error if the index is out of range.

pub fn get(&self, pcr_index: usize) -> Option<&[u8; 32]>

Get the current value of a PCR

pub fn get_extend_count(&self, pcr_index: usize) -> Option<u32>

Get the extend count for a PCR

pub fn is_extended(&self, pcr_index: usize) -> bool

Check if a PCR has been extended at least once
