Constructor Detail

DecryptingInputStream

public DecryptingInputStream(byte[] readKey,
                             InputStream inputStream)

Creates a new stream that decrypts data from the encapsulated stream.

Parameters:

readKey - The key to decrypt with.

inputStream - The wrapped InputStream.

Method Detail

available

public int available()
              throws IOException

Return the minimum number of bytes that can be read without blocking. Currently not synchronized.

Overrides:

available in class InputStream

Throws:

IOException

read

public int read(byte[] buf)
         throws IOException

Overrides:

read in class InputStream

Throws:

IOException

read

public int read(byte[] buf,
                int off,
                int len)
         throws IOException

Read up to "len" bytes into this buffer, starting at "off". If the layer above needs more data, it asks for more, so we are responsible only for blocking to fill at most one buffer, and returning "-1" on non-fault EOF status.

Overrides:

read in class InputStream

Throws:

IOException

read

public int read()
         throws IOException

Specified by:

read in class InputStream

Throws:

IOException

close

public void close()
           throws IOException

Specified by:

close in interface Closeable

Overrides:

close in class InputStream

Throws:

IOException

toString

public String toString()

Overrides:

toString in class Object
