java.lang.Objectorg.eclipse.emf.ecore.resource.impl.AESCipherImpl
public class AESCipherImpl
EMF implementation for the URIConverter.Cipher
interface using
the AES encryption algorithm.
This shows how this class can be used:
Map options = new HashMap(); options.put(Resource.OPTION_CIPHER, new AESCipherImpl("12345")); // "That's amazing! I've got the same combination on my luggage!" resource.save(options); resource.load(options);

java.io.InputStream |
decrypt(java.io.InputStream in)
Decrypts the specified input stream. |
java.io.OutputStream |
encrypt(java.io.OutputStream outputStream)
Encrypts the specified output stream. |
void |
finish(java.io.InputStream in)
This method is invoked after the decrypted input stream is used allowing the Cipher implementation to do any maintenance work required, such as flushing internal cache. |
void |
finish(java.io.OutputStream out)
This method is invoked after the encrypted output stream is used allowing the Cipher implementation to do any maintenance work required, such as flushing an internal cache. |

public void setKeysize(int keysize)
Sets the keysize to be used when creating the AES key. Using anything larger than 128 may make the data file non-portable.
The keysize cannot be changed after this Cipher is used.
