Interface DecryptedState

All Superinterfaces:

Serializable

public interface DecryptedState
extends Serializable

This interface represents the security state of an unlocked document. Clients can get this state from unlocked PDFDocument objects. This state information can be used to decrypt unlocked PDFDocument without need for entering user password or credential information.

Method Summary

Modifier and Type	Method and Description
byte[]	getEncryptKey() Get encryption key when no crypt filter is used
byte[]	getEncryptKey(String cryptFilter) Get encryption key corresponding to a cryptfilter
Integer	getPerms() Get perms flag
SecurityManager	getSecurityManager(CosDocument cosDocument) Get security manager for this decrypted state.
void	setEncryptKey(byte[] encryptKey) Set encryption key when no crypt filter is used
void	setEncryptKey(String cryptFilter, byte[] encryptKey) Set encryption key corresponding to a cryptfilter
void	setPerms(Integer mPerms) Set perms flag

Method Detail

getEncryptKey

byte[] getEncryptKey()

Get encryption key when no crypt filter is used

Returns:

byte[]

getEncryptKey

byte[] getEncryptKey(String cryptFilter)

Get encryption key corresponding to a cryptfilter

Returns:

byte[]

setEncryptKey

void setEncryptKey(String cryptFilter,
                   byte[] encryptKey)

Set encryption key corresponding to a cryptfilter

Parameters:

cryptFilter - Crypt filter

encryptKey - byte array representing encryption key

setEncryptKey

void setEncryptKey(byte[] encryptKey)

Set encryption key when no crypt filter is used

Parameters:

encryptKey - byte array representing encryption key

setPerms

void setPerms(Integer mPerms)

Set perms flag

Parameters:

mPerms -

getPerms

Integer getPerms()

Get perms flag

Returns:

Integer

getSecurityManager

SecurityManager getSecurityManager(CosDocument cosDocument)
                            throws PDFSecurityConfigurationException,
                                   PDFSecurityAuthorizationException,
                                   PDFCosParseException,
                                   PDFIOException,
                                   PDFSecurityException

Get security manager for this decrypted state. For new implementations of DecryptedState, clients need to return their own SecurityManager which will ensure that state information in this class is correctly used while decrypting.

Parameters:

cosDocument -

Returns:

SecurityManager

Throws:

PDFSecurityConfigurationException

PDFSecurityAuthorizationException

PDFCosParseException

PDFIOException

PDFSecurityException
