de.intarsys.pdf.crypt .ISecurityHandler

All known Subclasses:   de.intarsys.pdf.crypt .AbstractSecurityHandler,
ISecurityHandler
public interface ISecurityHandler extends ICryptHandler(Code)
The security handler as defined in the PDF spec. This is the exchangeable behavior in the PDF security spec.
The ISystemSecurityHandler is asked for de/encryption, which is done by himself for the defined standard encryptions, using ICryptHandler instances for RC4 and AES. These ICryptHandler instances are initialized using the encryption key provided by this ISecurityHandler .
With /V 4 encryption, thhe application may ask for "transparent" de/encryption, in which case it is forwared to the installed ISecurityHandler itself.

Method Summary
public void authenticate(IPasswordProvider passwordProvider)
     Perform an authentication of the current "user" on behalf of the information in the encryption dictionary.
public IAccessPermissions getAccessPermissions()
     The access permissions encoded in the encryption object for the current document or null if not applicable.
public byte[] getCryptKey()

public void init(STDocument document, COSEncryption encryption)


Method Detail
authenticate
public void authenticate(IPasswordProvider passwordProvider) throws COSSecurityException(Code)
Perform an authentication of the current "user" on behalf of the information in the encryption dictionary.
In most situations this will consist of checking user/owner password and setting the resulting access permissions.
throws:
  COSSecurityException -

getAccessPermissions
public IAccessPermissions getAccessPermissions()(Code)
The access permissions encoded in the encryption object for the current document or null if not applicable.
The access permissions are not standardized, may be these are not available from arbitrary handlers. The access permissions encoded in the encryption object for thecurrent document or null if not applicable.

getCryptKey
public byte[] getCryptKey()(Code)

init
public void init(STDocument document, COSEncryption encryption) throws COSSecurityException(Code)
