То есть, как считать эту самую подпись, непонятно
Я смотрел ваши примеры. Я реализовал код метода createCMSEx из файла CMS.java
Результат приведен выше. На вход метода в параметре buffer был передан результат следующего вычисления:
Код:private byte[] signMessage(String algoName, PrivateKey privateKey, String msg) throws NoSuchProviderException, NoSuchAlgorithmException, InvalidKeyException, SignatureException {
Signature signer = Signature.getInstance(algoName, JCP.PROVIDER_NAME);
signer.initSign(privateKey);
signer.update(msg.getBytes());
return signer.sign();
}
Видно, что если первые две подписи отличаются минимально, как я понимаю - отличается имитовставка, то подпись вычисленная в java коде отличается сильно.
Поэтому, далее войти на сайт не получается, так как подпись не опознаётся сайтом.
