    key: ByteArray, 
    algorithm: String = "HmacSHA256")

SessionTransportTransformerMessageAuthentication(
    keySpec: SecretKeySpec, 
    algorithm: String = "HmacSHA256")

Properties

algorithm	`val algorithm: String` is a message authentication algorithm name
keySpec	`val keySpec: SecretKeySpec` is a secret key spec for message authentication

Functions

transformRead	`fun transformRead(transportValue: String): String?` Un-apply a transformation for transportValue representing a transformed session. Returns null if it fails.
transformWrite	`fun transformWrite(transportValue: String): String` Apply a transformation for transportValue representing a session.
