org.bouncycastle.cms.CMSSignedDataGenerator
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);
