Class CMSEnvelopedDataStreamGenerator
public class CMSEnvelopedDataStreamGenerator
General class for generating a CMS enveloped-data message stream.
A simple example of usage.
CMSEnvelopedDataStreamGenerator edGen = new CMSEnvelopedDataStreamGenerator();
edGen.addKeyTransRecipient(cert);
ByteArrayOutputStream bOut = new ByteArrayOutputStream();
OutputStream out = edGen.open(
bOut, CMSEnvelopedDataGenerator.AES128_CBC, "BC");*
out.write(data);
out.close();

protected OutputStream | open(OutputStream out, String encryptionOID, SecretKey encKey, AlgorithmParameters params, ASN1EncodableVector recipientInfos, String provider)
|
OutputStream | open(OutputStream out, String encryptionOID, String provider) - generate an enveloped object that contains an CMS Enveloped Data
object using the given provider.
|
OutputStream | open(OutputStream out, String encryptionOID, int keySize, String provider) - generate an enveloped object that contains an CMS Enveloped Data
object using the given provider.
|
void | setBEREncodeRecipients(boolean berEncodeRecipientSet) - Use a BER Set to store the recipient information
|
void | setBufferSize(int bufferSize) - Set the underlying string size for encapsulated data
