It seems like setData() must be provided by classes using this trait. How about adding it as abstract method to this trait?

        $base = $this->getData();

It seems like getData() must be provided by classes using this trait. How about adding it as abstract method to this trait?

        return bin2hex($base);

    protected function decryption(string $encryption): ?string

        if (!ctype_xdigit($encryption)) {
            return null;

        if (strlen($encryption) % 2 !== 0) {
            return null;

        $encryption = hex2bin($encryption);

        $encryption = base64_decode($encryption);

        $encryption_iv = hex2bin($encryption_iv);

        $combined_key = CRYPTION_KEY . hex2bin($decryption_key);

        return openssl_decrypt($encrypted_data, CRYPTION_CIPHERING,

    }
