Class HKDFParams

Static ReadonlyINDEX

salt

• get salt(): Salt

  Returns the salt.

  Returns Salt

hashType

• get hashType(): HashType

  Returns the hash type.

  Returns HashType

Staticfrom

• from(__namedParameters?: { salt?: Salt; hashType?: HashType }): HKDFParams

  Parameters with a fresh random salt unless one is given.

  Parameters

  • __namedParameters: { salt?: Salt; hashType?: HashType } = {}

  Returns HKDFParams

index

• index(): number

  Returns the method index for CBOR encoding.

  Returns number

lock

• lock(contentKey: SymmetricKey, secret: Uint8Array): EncryptedMessage

  Derive a key from the secret and encrypt the content key.

  Parameters

  • contentKey: SymmetricKey
  • secret: Uint8Array

  Returns EncryptedMessage

unlock

• unlock(encryptedMessage: EncryptedMessage, secret: Uint8Array): SymmetricKey

  Derive a key from the secret and decrypt the content key.

  Parameters

  • encryptedMessage: EncryptedMessage
  • secret: Uint8Array

  Returns SymmetricKey

toString

• toString(): string

  Get string representation.

  Returns string

equals

• equals(other: HKDFParams): boolean

  Check equality with another HKDFParams.

  Parameters

  • other: HKDFParams

  Returns boolean

toCbor

• toCbor(): Cbor

  Convert to CBOR. Format: [0, Salt, HashType] (Salt is encoded as a tagged value — #6.40018(bytes))

  Returns Cbor

toCborData

• toCborData(): Uint8Array

  Convert to CBOR binary data.

  Returns Uint8Array

StaticfromCbor

• fromCbor(cborValue: Cbor): HKDFParams

  From the CBOR array, as the reference's TryFrom<CBOR> (a dcbor error): every failure is Cbor with the bare message. The index element is read as a usize (with dcbor's negative wrap) and its value ignored; the fixed-width fields wrap the same way.

  Parameters

  • cborValue: Cbor

  Returns HKDFParams
