init(privateKey:ciphersuite:info:encapsulatedKey:)

Declaration

init<SK>(privateKey: SK, ciphersuite: HPKE.Ciphersuite, info: Data, encapsulatedKey: Data) throws where SK : HPKEDiffieHellmanPrivateKey

Parameters

• privateKey:

  The recipient’s private key for decrypting the incoming messages.

• ciphersuite:

  The cipher suite that defines the cryptographic algorithms to use.

• info:

  Data that the key derivation function uses to compute the symmetric key material. The sender and the recipient need to use the same info data.

• encapsulatedKey:

  The encapsulated symmetric key that the sender provides.

Discussion

The Receiver decrypts messages in base mode using the encapsulated key with the key schedule information (info data).
