      • read

        public int read()
         throws java.io.IOException
        Read a byte from the stream. Blocking is dependent on the base stream.
        Specified by:
        read in class java.io.InputStream
        Returns:
        -1 if there are no more bytes from the stream otherwise the next byte value (0-255).
        Throws:
        java.io.IOException - Thrown if there is an IO error.

      • read

        public int read​(byte[] buffer,
                int offset,
                int count)
         throws java.io.IOException
        Read a sequance of bytes from the base stream into the buffer provided.
        Overrides:
        read in class java.io.InputStream
        Parameters:
        buffer - the buffer into which the data is read.
        offset - the start offset in array b at which the data is written.
        count - the maximum number of bytes to read.
        Returns:
        The number of bytes read.
        Throws:
        java.io.IOException - with an optional inner Exception if the base stream is a AesStream

      • close

        public void close()
           throws java.io.IOException
        Closes the base stream.
        Specified by:
        close in interface java.lang.AutoCloseable
        Specified by:
        close in interface java.io.Closeable
        Overrides:
        close in class java.io.InputStream
        Throws:
        java.io.IOException - Thrown if there is an IO error.

        java.io.IOException - Thrown if there is an IO error.

      • skip

        public long skip​(long pos)
          throws java.io.IOException
        Skip number of bytes on the stream.
        Overrides:
        skip in class java.io.InputStream
        Parameters:
        pos - the number of bytes to be skipped.
        Returns:
        The number of bytes that were skipped.
        Throws:
