Functions
QByteArray	randomBytes (int count)
quint64	randomUInt64 ()
QString	encryptSecret (const QByteArray &plaintext, const QByteArray &key, const QByteArray &aad={})
	Seal a secret with AES-256-GCM as "enc1:<b64 nonce>:<b64 ciphertext+tag>". Returns an empty string unless key is a valid 32-byte key and the cipher completes. aad is authenticated but not stored (bind the ciphertext to its context, e.g. the user name it belongs to).
QByteArray	decryptSecret (const QString &sealed, const QByteArray &key, const QByteArray &aad={})
	Open a string produced by encryptSecret(). Returns an empty array on any failure: unknown format, malformed base64, wrong key, wrong aad, or tampering.
