Добрый день. Пытаюсь получит подписанный контент.
Код подписание:
CMSSignedDataGenerator gen = new CMSSignedDataGenerator();
InputStream dataLoaded = this.getClass().getResourceAsStream("/Tickets.pdf");
byte[] data = dataLoaded.toString().getBytes();
Signature sig = Signature.getInstance(certToCheck.getSigAlgName(), provider);
KeyStore.PrivateKeyEntry pkEntry = (KeyStore.PrivateKeyEntry) store.getEntry(alias,new KeyStore.PasswordProtection(password.toCharArray()));
privateKey = pkEntry.getPrivateKey();
sig.initSign(privateKey);
sig.update(data);
CMSProcessableByteArray cmsData = new CMSProcessableByteArray(data);
gen.addSigner(privateKey, certToCheck, CMSSignedDataGenerator.DIGEST_SHA256);
CertStore chainStore = CertStore.getInstance("Collection", new CollectionCertStoreParameters(Arrays.asList(certToCheck)),provider.getName());
gen.addCertificatesAndCRLs(chainStore);
CMSSignedData signed = gen.generate(cmsData, true, provider.getName());
FileOutputStream fileOuputStream = new FileOutputStream("C:\\Test\\test_4.txt");
byte[] signedDataEncoded = signed.getEncoded();
fileOuputStream.write(Base64.encode(signedDataEncoded));
Сохраняю в формате txt. Внутри:

Проблема в линии:

Почему он не может прочитать?
Если ли примеры ?
В интернете нашел код который и отталкивался(
www.programcreek.com/java-api-examples/?...t/etee/SealTest.java):
CMSTypedData signedContent = cmsSignedData.getSignedContent();
byte[] data = (byte[]) signedContent.getContent();
// decrypt content
CMSEnvelopedDataParser cmsEnvelopedDataParser = new CMSEnvelopedDataParser(
data);
Но там
CMSTypedData а у меня
CMSProcessableByteArray , так как в библиотеке KALKAN нету обьекта с типом CMSTypedData.
