Examples of org.bouncycastle2.crypto.BufferedBlockCipher

org.bouncycastle2.crypto.digests.RIPEMD256Digest
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.

            ivLength = baseEngine.getBlockSize();
            if (ivLength < 16)
            {
                throw new IllegalArgumentException("Warning: SIC-Mode can become a twotime-pad if the blocksize of the cipher is too small. Use a cipher with a block size of at least 128 bits (e.g. AES)");
            }
            cipher = new BufferedGenericBlockCipher(new BufferedBlockCipher(
                        new SICBlockCipher(baseEngine)));
        }
        else if (modeName.startsWith("CTR"))
        {
            ivLength = baseEngine.getBlockSize();
            cipher = new BufferedGenericBlockCipher(new BufferedBlockCipher(
                        new SICBlockCipher(baseEngine)));
        }
        else if (modeName.startsWith("GOFB"))
