Constructor Detail

EncryptedContentInfo

public EncryptedContentInfo()
                     throws SMIMEException

Constructs empty Encrypted Content Info. All methods: addContentType, addEncryptAlgorithmID and addEncryptContent must be performed after construction for obtaining valid CMS object.

Throws:

SMIMEException - thrown from super class constructor.

Method Detail

addContentType

public void addContentType(byte[] contType0)
                    throws SMIMEException

Adds Content Type

Parameters:

contType0 - Content Type represented as byte array

Throws:

SMIMEException - if order of adding components is wrong. Also, it can be thrown from super class addContent method.

addEncryptAlgorithmID

public void addEncryptAlgorithmID(byte[] alg0)
                           throws SMIMEException

Adds Encrypted Algorithm Identifier

Parameters:

alg0 - Encrypted Algorithm Identifier represented as byte array

Throws:

SMIMEException - if order of adding components is wrong. Also, it can be thrown from super class addContent method.

addEncryptContent

public void addEncryptContent(byte[] cont0)
                       throws SMIMEException

Adds Encrypted Content

Parameters:

cont0 - encrypted content as byte array

Throws:

SMIMEException - if order of adding components is wrong. Also, it can be thrown from super class addContent method.
