+
+Если доступен `rhash`, посчитайте ГОСТ и сравните с суммой вендора. ФИКС

+несколько вариантов:
+
+```sh
+rhash --gost "$ISO"
+rhash --gost --gost-reverse "$ISO"
+rhash --gost-cryptopro "$ISO"
+rhash --gost-cryptopro --gost-reverse "$ISO"
+```
+
+Для ISO `049-16-d-01.iso` сумма вендора совпала с `rhash --gost`.
+
+Подлинность принимается, если совпала ГОСТ-сумма **или** одновременно
+выполнены все условия ниже:
+
+- volume id ISO = `KESL12SP4`;
+- внутри есть `kesl/kesl_12.4.0-1225_amd64.deb`;
+- SHA-256 ISO зафиксирован в evidence;
+- источник — официальный канал вендора.
+
+Файл `.sig` без доверенного публичного ключа не заменяет эту проверку.
+
+Только после совпадения хеша смонтируйте ISO только для чтения и найдите
+`kesl_*_amd64.deb` без GUI:
+
+```sh
+install -d -m 0700 -o root -g root /root/kesl-install /mnt/kesl-iso
+mount -o ro,loop "$ISO" /mnt/kesl-iso
+find /mnt/kesl-iso -type f \( -iname '*kesl*' -o -iname '*.deb' \) | sort
+```
+
+Ожидается имя вида `kesl_12.4.0-*_amd64.deb`. Не копируйте `kesl-gui`, i386,
+arm64, RPM, KSC agent и Windows-пакеты. Если внутри только 12.0.x или нет
+amd64 DEB — stop: для Ubuntu 24.04 нужен KESL 12.4.
