      public OutputStreamStandardEncryption (OutputStream out, byte[] key, int off, int len)
      Creates a new instance of OutputStreamStandardEncryption
      Parameters:
      out - the OutputStream to which data will be written
      key - data to be written
      off - the start offset in data
      len - number of bytes to write

  • Method Details

    • write

      public void write (byte[] b, int off, int len) throws IOException
      Writes len bytes from the specified byte array starting at offset off to this output stream. The general contract for write(b, off, len) is that some of the bytes in the array b are written to the output stream in order; element b[off] is the first byte written and b[off+len-1] is the last byte written by this operation.

      The write method of OutputStream calls the write method of one argument on each of the bytes to be written out. Subclasses are encouraged to override this method and provide a more efficient implementation.

      If b is null, a NullPointerException is thrown.

      If off is negative, or len is negative, or off+len is greater than the length of the array b, then an IndexOutOfBoundsException is thrown.

      Specified by:
      write in class OutputStreamEncryption
      Parameters:
      b - the data.
      off - the start offset in the data.
      len - the number of bytes to write.
      Throws:
      IOException - if an I/O error occurs. In particular, an IOException is thrown if the output stream is closed.
