Method Detail

setEncoding

public void setEncoding(java.lang.String encoding)

Specify use of definite-length/DER rather than indefinite length encoding ("BER").

The in-memory generators honour the choice all the way through their generate() methods - in the definite-length modes the encrypted content is carried as a primitive definite-length OCTET STRING, with "DER" additionally sorting the sets the generator builds. The streaming generators that support definite-length output need the content length supplied up front via their length-taking open() methods; see the individual open() javadoc.

Parameters:

encoding - one of "DER", "DL", "BER".

setUnprotectedAttributeGenerator

public void setUnprotectedAttributeGenerator(CMSAttributeTableGenerator unprotectedAttributeGenerator)

setOriginatorInfo

public void setOriginatorInfo(OriginatorInformation originatorInfo)

addRecipientInfoGenerator

public void addRecipientInfoGenerator(RecipientInfoGenerator recipientGenerator)

Add a generator to produce the recipient info required.

Parameters:

recipientGenerator - a generator of a recipient info object.
