privateKey property
Optional PKCS#8 DER bytes for ZKE (Zero-Knowledge Encryption) mode.
When set, the E2EE layer uses this persistent device key instead of
generating a fresh ephemeral key per client instance. The key is loaded
via e2eeKeyPairFromPkcs8.
Obtain a device key with: bella auth setup. To convert a PEM or base64
string (e.g. BELLA_BAXTER_PRIVATE_KEY) use bellaPrivateKeyFromEnvValue.
When null (default) an ephemeral P-256 key pair is generated automatically.
Implementation
final Uint8List? privateKey;
