Struct aes128gcm

credentials/alts/internal/conn/aes128gcm.go:37–44

aes128gcm is the struct that holds necessary information for ALTS record. The counter value is NOT included in the payload during the encryption and decryption operations.

// The counter value is NOT included in the payload during the encryption and
// decryption operations.
type aes128gcm struct {
	// inCounter is used in ALTS record to check that incoming counters are
	// as expected, since ALTS record guarantees that messages are unwrapped
	// in the same order that the peer wrapped them.
	inCounter  Counter
	outCounter Counter
	aead       cipher.AEAD
}

// NewAES128GCM creates an instance that uses aes128gcm for ALTS record.
