AgileDecryptor |
clone() |
InputStream |
getDataStream(DirectoryNode dir)
Return a stream with decrypted data.
|
long |
getLength()
Returns the length of the encrypted data that can be safely read with
Decryptor.getDataStream(org.apache.poi.poifs.filesystem.DirectoryNode) . |
boolean |
verifyPassword(KeyPair keyPair,
X509Certificate x509)
instead of a password, it's also possible to decrypt via certificate.
|
boolean |
verifyPassword(String password)
set decryption password

public boolean verifyPassword(String password) throws GeneralSecurityException
verifyPassword
in class Decryptor
GeneralSecurityException
public boolean verifyPassword(KeyPair keyPair, X509Certificate x509) throws GeneralSecurityException
keyPair
- x509
- GeneralSecurityException
public InputStream getDataStream(DirectoryNode dir) throws IOException, GeneralSecurityException
Decryptor
Use Decryptor.getLength()
to get the size of that data that can be safely read from the stream.
Just reading to the end of the input stream is not sufficient because there are
normally padding bytes that must be discarded
getDataStream
in class Decryptor
dir
- the node to read fromIOException
GeneralSecurityException
public long getLength()
Decryptor
Decryptor.getDataStream(org.apache.poi.poifs.filesystem.DirectoryNode)
.
Just reading to the end of the input stream is not sufficient because there are
normally padding bytes that must be discarded
The length variable is initialized in Decryptor.getDataStream(org.apache.poi.poifs.filesystem.DirectoryNode)
,
an attempt to call getLength() prior to getDataStream() will result in IllegalStateException.
public AgileDecryptor clone() throws CloneNotSupportedException
