+--org.bouncycastle.openpgp.PGPEncryptedData
- Direct Known Subclasses:
- PGPPBEEncryptedData, PGPPublicKeyEncryptedData
- public abstract class PGPEncryptedData
- extends java.lang.Object
- implements SymmetricKeyAlgorithmTags
A PGP encrypted data object.
Encrypted data packets are decrypted using a PGPDataDecryptor
obtained from a
PGPDataDecryptorFactory
.

getInputStream
public java.io.InputStream getInputStream()
- Return the raw input stream for the data stream.
Note this stream is shared with all other encryption methods in the same
PGPEncryptedDataList
and with any decryption methods in sub-classes, so consuming
this stream will affect decryption.
- Returns:
- the encrypted data in this packet.
isIntegrityProtected
public boolean isIntegrityProtected()
- Checks whether the packet is integrity protected.
- Returns:
true
if there is a modification detection code package associated with
this stream
verify
public boolean verify()
throws PGPException,
java.io.IOException
- Verifies the integrity of the packet against the modification detection code associated with
it in the stream.
Note: This can only be called after the message has been read.
- Returns:
true
if the message verifies, false
otherwise.- Throws:
- PGPException - if the message is not
integrity
protected
.
