public interface Content

extends ContentStream

The interface for the non-stream implementations of the PKCS#7 content types.

This interface extends the ContentStream interface about the decode(ASN1Object obj) method that additionally has to be implemented by any class that represents the non-stream implementation of one the several PKCS#7 content types. Within the IAIK-JCE PKCS#7 package, this interface is implemented for all six content types specified by PKCS#7, Version 1.5:

• Data
• SignedData
• EnvelopedDate
• SignedAndEnvelopedData
• DigestedData
• EncryptedData

Implementations of this interface do not represent the contentType field of the PKCS#7 ContentInfo structure. They represent the ASN.1 structures defined in the PKCS#7 specification for the several PKCS#7 content types. Implementations of this interface are instantiated for supplying values for the content field of the PKCS#7 ContentInfo structure.
