Struct MessageVerification 

pub struct MessageVerification {
    pub session: Session,
    pub ttl_ms: u64,
    pub ts_ms: u128,
    pub sig: Vec<u8>,
}

Message Verification is based on session, and sig. it also included ttl time and created ts.

Fields

session: Session

The Session of the SessionSk. Used to identify a sender and verify the signature.

ttl_ms: u64

The time to live of the message in milliseconds.

ts_ms: u128

The timestamp of the message in milliseconds.

sig: Vec<u8>

The signature of the message. Signed by SessionSk. Can be verified by Session.

Implementations

impl MessageVerification

pub fn new( data: &[u8], session_sk: &SessionSk, ) -> Result<MessageVerification, Error>

Create a new MessageVerification. Should provide the data and the SessionSk.

pub fn verify(&self, data: &[u8]) -> bool

Verify a MessageVerification

pub fn is_expired(&self) -> bool

Return whether the verification timestamp is outside its accepted lifetime.

pub fn is_live_at(&self, now_ms: u128) -> bool

Return whether the verification timestamp and TTL describe a currently live proof.

Pre: now_ms is the receiver’s current wall-clock time. Post: true implies ttl_ms <= MAX_TTL_MS, the timestamp is not beyond the accepted future skew, and now_ms has not passed ts_ms + ttl_ms.

pub fn verify_unexpired(&self, data: &[u8]) -> bool

Verify the signature only when the verification timestamp is still live.
