Class: SealedMessage

Defined in: envelope.ts:29

A sealed (encrypted) message: KEM ciphertext + AES-256-GCM ciphertext + metadata, serialized as CBOR identical to quantum-safe-py's SealedMessage.

Properties

aad

readonly aad: Uint8Array

Defined in: envelope.ts:41

The caller's additional authenticated data (empty by default).

---

algorithm

readonly algorithm: string

Defined in: envelope.ts:33

KEM algorithm the message was sealed to, e.g. X25519+ML-KEM-768.

---

ciphertext

readonly ciphertext: Uint8Array

Defined in: envelope.ts:39

AES-256-GCM ciphertext followed by the 16-byte tag.

---

kemCiphertext

readonly kemCiphertext: Uint8Array

Defined in: envelope.ts:35

The hybrid KEM ciphertext (HybridCipherText.to_bytes()).

---

nonce

readonly nonce: Uint8Array

Defined in: envelope.ts:37

12-byte AES-GCM nonce.

---

version

readonly version: number

Defined in: envelope.ts:31

Envelope format version (currently 1).

Methods

inspect()

inspect(): SealedInfo

Defined in: envelope.ts:98

Non-secret metadata.

Returns

SealedInfo

---

toBytes()

toBytes(): Uint8Array

Defined in: envelope.ts:90

CBOR serialization (copy).

Returns

Uint8Array

---

toHex()

toHex(): string

Defined in: envelope.ts:94

Lowercase hex of SealedMessage.toBytes.

Returns

string

---

toString()

toString(): string

Defined in: envelope.ts:101

Returns

string

---

fromBytes()

static fromBytes(data): SealedMessage

Defined in: envelope.ts:60

Parses CBOR bytes (from toBytes() or quantum-safe-py SealedMessage.to_bytes()).

Parameters

data

Uint8Array

Returns

SealedMessage

---

fromHex()

static fromHex(hex): SealedMessage

Defined in: envelope.ts:64

Parses a hex string produced by toHex() / quantum-safe-py to_hex().

Parameters

string

Returns

SealedMessage

---

fromParts()

Defined in: envelope.ts:68

Assembles a sealed message from its fields (for example data stored in separate columns).
