- public class CMSSignedDataGenerator
- extends CMSSignedGenerator
general class for generating a pkcs7-signature message.
A simple example of usage, generating a detached signature.
List certList = new ArrayList();
CMSTypedData msg = new CMSProcessableByteArray("Hello world!".getBytes());
certList.add(signCert);
Store certs = new JcaCertStore(certList);
CMSSignedDataGenerator gen = new CMSSignedDataGenerator();
ContentSigner sha1Signer = new JcaContentSignerBuilder("SHA1withRSA").setProvider("BC").build(signKP.getPrivate());
gen.addSignerInfoGenerator(
new JcaSignerInfoGeneratorBuilder(
new JcaDigestCalculatorProviderBuilder().setProvider("BC").build())
.build(sha1Signer, signCert));
gen.addCertificates(certs);
CMSSignedData sigData = gen.generate(msg, false);
