Class CMSAuthenticatedDataStreamGenerator
java.lang.Object
org.bouncycastle.cms.CMSEnvelopedGenerator
org.bouncycastle.cms.CMSAuthenticatedGenerator
org.bouncycastle.cms.CMSAuthenticatedDataStreamGenerator
General class for generating a CMS authenticated-data message stream.
A simple example of usage.
CMSAuthenticatedDataStreamGenerator edGen = new CMSAuthenticatedDataStreamGenerator(); edGen.addRecipientInfoGenerator(new JceKeyTransRecipientInfoGenerator(cert).setProvider("BC")); ByteArrayOutputStream bOut = new ByteArrayOutputStream(); OutputStream out = edGen.open( bOut, new JceCMSMacCalculatorBuilder(CMSAlgorithm.DES_EDE3_CBC).setProvider("BC").build());* out.write(data); out.close();

setBufferSize
public void setBufferSize(int bufferSize) Set the underlying string size for encapsulated data- Parameters:
bufferSize
- length of octet strings to buffer the data.
-
setBEREncodeRecipients
public void setBEREncodeRecipients(boolean useBerEncodingForRecipients) Use a BER Set to store the recipient information. By default recipients are stored in a DER encoding.- Parameters:
useBerEncodingForRecipients
- true if a BER set should be used, false if DER.
-
