erase method
void
erase()
Securely overwrites all sensitive data with zeros.
Call this method after successfully sending the verifiers to the server to prevent the ephemeral key and session verifier from lingering in memory.
Implementation
void erase() {
userId = ''; // Allows string to be GC.
ephemeralUserPublicKey.overwriteWithZeros();
sessionKeyVerifier.overwriteWithZeros();
}
