Examples of BufferedBlockCipher

org.bouncycastle.crypto.BufferedBlockCipher
A wrapper class that allows block ciphers to be used to process data in a piecemeal fashion. The BufferedBlockCipher outputs a block only when the buffer is full and more data is being added, or on a doFinal.
Note: in the case where the underlying cipher is either a CFB cipher or an OFB one the last block may not be a multiple of the block size.
