Examples of CMSSignedDataGenerator

org.bouncycastle.cms.CMSSignedDataGenerator

general class for generating a pkcs7-signature message.

A simple example of usage.

 CertStore               certs... CMSSignedDataGenerator    gen = new CMSSignedDataGenerator(); gen.addSigner(privKey, cert, CMSSignedGenerator.DIGEST_SHA1); gen.addCertificatesAndCRLs(certs); CMSSignedData           data = gen.generate(content, "BC");
