Implementations§

§

impl KeyPackageIn

pub fn unverified_credential(&self) -> CredentialWithKey

Returns a [CredentialWithKey] from the unverified payload

pub async fn validate( self, backend: &impl OpenMlsCryptoProvider, protocol_version: ProtocolVersion, group: &PublicGroup, sender: bool, ) -> Result<KeyPackage, KeyPackageVerifyError>

Verify that this key package is valid:

  • verify that the signature on this key package is valid
  • verify that the signature on the leaf node is valid
  • verify that all extensions are supported by the leaf node
  • make sure that the lifetime is valid
  • make sure that the init key and the encryption key are different
  • make sure that the protocol version is valid

Returns a KeyPackage after having verified the signature or a [KeyPackageVerifyError] otherwise.

pub async fn standalone_validate( self, backend: &impl OpenMlsCryptoProvider, protocol_version: ProtocolVersion, sender: bool, ) -> Result<KeyPackage, KeyPackageVerifyError>

Verify that this key package is valid disregarding the group it is supposed to be used with.

pub fn credential(&self) -> &Credential
