data class MessageKeys(val chachaKey: ByteArray, val chachaNonce: ByteArray, val hmacKey: ByteArray)

Container for per-message cryptographic keys.

Holds the ephemeral keys derived for encrypting/decrypting a single message. Keys should be cleared from memory after use via clear.

Constructors

constructor(chachaKey: ByteArray, chachaNonce: ByteArray, hmacKey: ByteArray)

Properties

val chachaKey: ByteArray

The 32-byte ChaCha20 encryption key

val chachaNonce: ByteArray

The 12-byte ChaCha20 nonce

val hmacKey: ByteArray

The 32-byte HMAC-SHA256 key

Functions

fun clear()

Securely clears all keys from memory by overwriting with zeros.
