    • RACFOutputStream

      public RACFOutputStream(String userID, String ringid, char[] passwd) throws IOException
      Constructs an instance of RACFOutputStream. A RACFOutputStream is used to write certificates and keys to a RACF key ring.
      Parameters:
      userID - a string containing the ID of the user that owns the keyring
      ringid - a string containing the name of the RACF key ring
      passwd - a character array containing the password for the keystore
      Throws:
      IOException - if there is an error writing keys and certificates to the key ring.

  • Method Details

    • write

      public void write(int b) throws IOException
      Writes the specified byte to this output stream.
      Specified by:
      write in class OutputStream
      Parameters:
      b - the byte to write
      Throws:
      IOException - if an I/O error occurs. In particular, an IOException may be thrown if the output stream has been closed.

    • write

      public void write(byte[] b) throws IOException
      Writes b.length bytes from the specified byte array to this output stream.
      Overrides:
      write in class OutputStream
      Parameters:
      b - the data
      Throws:
      IOException - if an I/O error occurs. In particular, an IOException may be thrown if the output stream has been closed.

    • 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.
      Overrides:
      write in class OutputStream
      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 may be thrown if the output stream has been closed.

    • close

      public void close() throws IOException
      Closes this output stream and releases any system resources associated with this stream.
      Specified by:
      close in interface AutoCloseable
      Specified by:
      close in interface Closeable
      Overrides:
      close in class OutputStream
      Throws:
      IOException - if an I/O error occurs.

    • flush

      public void flush() throws IOException
      Flushes this output stream. Parse the header and the accumulated entries added by JceRACFKeyStore. Write the parsed data into a buffer to be used by the underlying JNI code to add certificates and keys to the RACF key ring. Finally, resets the accumulated data.
      Specified by:
      flush in interface Flushable
      Overrides:
      flush in class OutputStream
      Throws:
      IOException - if an I/O error occurs.
