RepeatableCipherInputStream

public RepeatableCipherInputStream(java.io.InputStream input,
                           CipherFactory cipherFactory)

Constructs a new repeatable cipher input stream using the specified InputStream as the source data, and the CipherFactory for building Cipher objects.

パラメータ:

input - The original, unencrypted data stream. This stream should be markable/resetable in order for this class to work correctly.

cipherFactory - The factory used for creating identical cipher objects when this stream is reset and a new CipherInputStream is needed.
