type SharedSecretEncryptions 

type SharedSecretEncryptions struct {
	// (secret key chosen by dealer) * g, X25519 point
	DiffieHellmanPoint [curve25519.PointSize]byte

	// keccak256 of plaintext sharedSecret.
	//
	// Since SharedSecretEncryptions are shared through a smart contract, each
	// oracle will see the same SharedSecretHash. After decryption, oracles can
	// check their sharedSecret against SharedSecretHash to prevent the dealer
	// from equivocating
	SharedSecretHash common.Hash

	// Encryptions of the shared secret with one entry for each oracle. The
	// i-th oracle can recover the key as follows:
	//
	// 1. key := Keccak256(DH(DiffieHellmanPoint, process' secret key))[:16]
	// 2. sharedSecret := AES128DecryptBlock(key, Encryptions[i])
	//
	// See Decrypt for details.
	Encryptions []encryptedSharedSecret
}

SharedSecretEncryptions is the encryptions of SharedConfig.SharedSecret, using each oracle's SharedSecretEncryptionPublicKey.

We use a custom encryption scheme to be more space-efficient (compared to standard AEAD schemes, nacl crypto_box, etc...), which saves gas in transmission to the OCR2Aggregator.

func EncryptSharedSecret 

func EncryptSharedSecret(
	keys []ocrtypes.SharedSecretEncryptionPublicKey,
	sharedSecret *[SharedSecretSize]byte,

	sharedSecret *[SharedSecretSize]byte,
	sk *[32]byte,
) SharedSecretEncryptions

EncryptSharedSecretInternal constructs a SharedSecretEncryptions from a set of SharedSecretEncryptionPublicKeys, the sharedSecret, and an ephemeral secret key sk
