Implementations§

Source§

impl Capsule

Source

pub fn create( dim: u16, payload: &[u8], flags: CapsuleFlags, sk: &SigningKey, ) -> Result<Self, LllvError>

Cria uma cápsula assinada.

§Errors
  • LllvError::TimestampOverflow se o timestamp não couber em u64
  • LllvError::MismatchedLengths se o payload exceder u32::MAX
  • LllvError::Crypto se a assinatura falhar
Source

pub fn to_bytes(&self) -> Vec<u8>

Source

pub fn from_bytes(raw: &[u8]) -> Result<Self, LllvError>

§Errors
  • LllvError::InvalidHeaderLen se o buffer for curto
  • LllvError::MismatchedLengths se o payload não corresponder ao header
Source

pub fn verify_cid(&self) -> Result<(), LllvError>

Verifica integridade (CID cobre payload). Não verifica autoria.

§Errors
  • LllvError::BadSignature se o CID recalculado divergir
Source

pub fn verify_with(&self, pk: &VerifyingKey) -> Result<(), LllvError>

Verifica integridade e autenticidade com a chave pública.

§Errors
  • Propaga erros de verify_cid
  • LllvError::BadSignature se a verificação Ed25519 falhar
Source

pub fn verify(&self) -> Result<(), LllvError>

👎Deprecated since 0.1.0: use verify_with(&pk) para autenticidade ou verify_cid() para integridade

Verifica integridade somente (equivalente a verify_cid).

§Errors
  • Propaga os mesmos erros de verify_cid
