Types ¶

type Decrypt ¶

type Decrypt struct {
	// contains filtered or unexported fields
}

Decrypt for HPKE implements interface HybridDecrypt.

func NewDecrypt ¶

func NewDecrypt(recipientPrivKey *pb.HpkePrivateKey) (*Decrypt, error)

NewDecrypt constructs a Decrypt using HpkePrivateKey.

func (*Decrypt) Decrypt ¶

func (d *Decrypt) Decrypt(ciphertext, contextInfo []byte) ([]byte, error)

Decrypt decrypts ciphertext, verifying the integrity of contextInfo.

type Encrypt ¶

type Encrypt struct {
	// contains filtered or unexported fields
}

Encrypt for HPKE implements interface HybridEncrypt.

func NewEncrypt ¶

func NewEncrypt(recipientPubKey *pb.HpkePublicKey) (*Encrypt, error)

NewEncrypt constructs an Encrypt using HpkePublicKey.

func (*Encrypt) Encrypt ¶

func (e *Encrypt) Encrypt(plaintext, contextInfo []byte) ([]byte, error)

Encrypt encrypts plaintext, binding contextInfo to the resulting ciphertext.
