Fields

envelope_version: u16

Envelope version.

header_length: u32

Canonical header length in bytes.

flags: u32

Extension flags reserved for future formats.

algorithm: DntAlgorithm

Authenticated encryption algorithm.

application_id: ApplicationId

Application that owns this envelope.

tenant_id: Option<TenantId>

Optional tenant boundary.

content_type: ContentType

Logical content type.

codec_id: CodecId

Payload codec identifier.

key_id: KeyId

Rotation-aware key identifier.

schema_version: u32

Payload schema version, independent of envelope version.

created_at_ms: u64

Creation timestamp in Unix milliseconds.

payload_length: u64

Stored encoded payload length, after any authenticated compression.

nonce: [u8; 24]

AEAD nonce.

payload_hash: [u8; 32]

Keyed digest of the stored encoded payload.

public_metadata: Vec<u8>

Authenticated public metadata bytes.

encrypted_metadata_length: u32

Encrypted metadata length stored inside AEAD plaintext.
