Java Security

Hi,
My AES key has some characters like '$' etc. So the normal methods to convert string to byte and byte to string didn't seem to work because they use this set of characters.

public static String strHexVal = "0123456789abcdef";

So I have started using CharsetEncoder, ByteBuffer and CharBuffer and now I am able to encode and decode this sample string successfully.

ByteBuffer bbuf = encoder.encode(CharBuffer.wrap( "Te$$$st" ));

		    CharBuffer cbuf = decoder.decode(bbuf);

But when I use this code to read an actual key from a JCEKS keystore

	        Key key = store.getKey( "aesfileencryption", getPassword() );

	        CharBuffer cbuf = decoder.decode( key.getEncoded() );

I don't get the correct key.

What am I missing ?


Thanks,
Mohan
