I pulled this example from the following link. I am having problems because I can't get the compiler to find the CMSProcessableInputStream class.
Does anyone have any suggestions?
This is a snippet of my pom.xml:
<dependency>
<groupId>org.apache.pdfbox</groupId>

</dependency>
<dependency>
<groupId>org.bouncycastle</groupId>
<artifactId>bcprov-ext-jdk16</artifactId>
<version>1.46</version>
</dependency>
This is the code:
@Override
public byte[] sign(InputStream content) throws SignatureException,
IOException {
CMSProcessableInputStream input = new CMSProcessableInputStream(content);
CMSSignedDataGenerator gen = new CMSSignedDataGenerator();
// CertificateChain
List<Certificate> certList = Arrays.asList(cert);
CertStore certStore = null;
try {
certStore = CertStore.getInstance("Collection",
new CollectionCertStoreParameters(certList), provider);
gen.addSigner(privKey, (X509Certificate) certList.get(0),
CMSSignedGenerator.DIGEST_SHA256);
gen.addCertificatesAndCRLs(certStore);
CMSSignedData signedData = gen.generate(input, false, provider);
return signedData.getEncoded();
} catch (Exception e) {
// should be handled
System.err.println("Error while creating pkcs7 signature.");
e.printStackTrace();
}
throw new RuntimeException("Problem while preparing signature");
}
