Types

type ECDHAEADCompositeDecrypt

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

ECDHAEADCompositeDecrypt is an instance of AES-GCM decryption in the context of ECDH/concat kdf WK of CEK and AEAD content decryption.

func NewECDHAEADCompositeDecrypt

func NewECDHAEADCompositeDecrypt(encHelper composite.EncrypterHelper, cek []byte) *ECDHAEADCompositeDecrypt

NewECDHAEADCompositeDecrypt returns ECDH composite decryption construct with Concat KDF/ECDH-ES key unwrapping and AEAD payload decryption.

func (*ECDHAEADCompositeDecrypt) Decrypt

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

Decrypt using composite ECDH-ES with a Concat KDF key unwrap and AEAD content decryption.

type ECDHAEADCompositeEncrypt

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

ECDHAEADCompositeEncrypt is an instance of ECDH-ES encryption with Concat KDF and AEAD content encryption.

func NewECDHAEADCompositeEncrypt

func NewECDHAEADCompositeEncrypt(encHelper composite.EncrypterHelper, cek []byte) *ECDHAEADCompositeEncrypt

NewECDHAEADCompositeEncrypt returns ECDH (KW done outside of this Tink key implementation) AES encryption construct for AEAD content encryption.

func (*ECDHAEADCompositeEncrypt) Encrypt

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

Encrypt using composite ECDH with a Concat KDF key wrap and CBC+HMAC content encryption.
