Struct Device

pub struct Device { /* private fields */ }

Represents PlayReady device. Usually created from .prd file.

Implementations

impl Device

pub fn new( group_key: Option<SigningKey>, encryption_key: Keypair<Generic<NistP256>>, signing_key: SigningKey, cert_chain: CertificateChain, ) -> Self

Creates new Device.

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

Creates new Device from bytes.

pub fn from_prd(path: impl AsRef<Path>) -> Result<Self, Error>

Creates new Device from .prd file.

Arguments

path - path to .prd file

pub fn signing_key(&self) -> &SigningKey

Returns device signing key.

pub fn encryption_key(&self) -> &Keypair<Generic<NistP256>>

Returns device encryption key.

pub fn group_certificate(&self) -> &[u8]

Returns device group certificate.

pub fn group_key(&self) -> Option<&SigningKey>

Returns device group key.

pub fn name(&self) -> Result<String, Error>

Returns name of the device parsed from certificate chain.

pub fn security_level(&self) -> Result<u32, Error>

Returns security level (SL????) of the device parsed from certificate chain.

pub fn verify_certificates(&self) -> Result<(), Error>

Performs signature verification of certificates bundled in CertificateChain.

pub fn provision( cert_chain: CertificateChain, group_key: SigningKey, ) -> Result<Self, Error>

pub fn reprovision(self) -> Result<Self, Error>

Generates reprovisioned Device.

pub fn provision_from_files( group_cert_path: impl AsRef<Path>, group_key_path: impl AsRef<Path>, ) -> Result<Self, Error>

Creates and provisions device from file containing certificate chain (usually named bgroupcert.dat) and file with group key (usually zgpriv.dat).

pub fn write_to_file(&self, path: impl AsRef<Path>) -> Result<(), Error>

Serializes and writes device to file specified by path.
