Notes:
Changes:
0.3 February 25th, 2006 new encrypted file support by Dirk (dirk.barnikel@gmx.de) Thanks Dirk.
* Added test case for the file-related stuff. file-stuff
seems to work fine
* Replaced hard coded IO buffersize (512) with class attribute
Key#block_size and default value.
* Modification to create {De,En}crypters only via the factory methods
Key#{de,en}crypter.
* Added Key#{de,en}crypt_file methods that take a file and de- or encrypts it.
* The methods are implemented to call the cipher with small chunks of data (512 bytes) to keep memory usage low.
* By default, the original file is first overwritten and then removed.
* This overwrite is not really safe but should make it harder to restore the data of the removed file from the filesystem.
* Added Key#{store,load} methods that read and write Key data to/from files.
* Added Key#safe_{create,delete,read} methods to encapsulate the handling of files inside EzCrypto.
