Class CMSRecipientInfo

java.lang.Object

oracle.security.crypto.cms.CMSRecipientInfo

All Implemented Interfaces:

oracle.security.crypto.asn1.ASN1Object, oracle.security.crypto.util.Streamable

Direct Known Subclasses:

CMSKEKRecipientInfo, CMSKeyTransRecipientInfo

public abstract class CMSRecipientInfo
extends java.lang.Object
implements oracle.security.crypto.asn1.ASN1Object

The base class for all CMSRecipientInfo Objects.

A CMSRecipientInfo supports differents key management techniques:

• Key Transport - CMSKeyTransRecipientInfo

See Also:

• Key Agreement - CMSKeyAgreeRecipientInfo (Will be Supported in the next Release) oracle.security.crypto.cert.cms.CMSKeyAgreeRecipientInfo
• Symmetric Key-Encryption Keys - CMSKEKRecipientInfo,

Constructor Detail

CMSRecipientInfo

public CMSRecipientInfo()

Create an empty CMSRecipientInfo.

CMSRecipientInfo

public CMSRecipientInfo(java.io.InputStream is)
                 throws java.io.IOException

Create a new CMSRecipientInfo by reading the BER encoding from the specified input stream.

Parameters:

is - The input stream.

Throws:

java.io.IOException - The encoding is incorrect or an I/O error occurs.

Method Detail

input

public void input(java.io.InputStream is)
           throws java.io.IOException

Read the BER encoded CMSRecipientInfo structure from the input stream.

Specified by:

input in interface oracle.security.crypto.util.Streamable

Parameters:

is - The input stream.

Throws:

java.io.IOException - The input encoding is incorrect or an I/O error occurs.

inputInstance

public static CMSRecipientInfo inputInstance(java.io.InputStream is)
                                      throws java.io.IOException

Create and intialize a CMSRecipientInfo by reading the BER encoding from the specified input stream.

Parameters:

is - The input stream.

Returns:

The CMSRecipientInfo Object.

Throws:

java.io.IOException - The encoding is incorrect or an I/O error occurs.

inputRecipientInfo

protected abstract void inputRecipientInfo(java.io.InputStream is)
                                    throws java.io.IOException

Reads the CMSRecipientInfo structure. This method must be implemented by subclasses.

The input stream is positioned at the beginning of the tag octet of the SEQUENCE encoding.

Parameters:

is - The input stream.

Throws:

java.io.IOException - The encoding is incorrect or an I/O error occurs.

getVersion

public abstract oracle.security.crypto.asn1.ASN1Integer getVersion()

Returns the Version of the CMSRecipientInfo. This method must be implemented by subclasses.

Returns:

The version number.
