code: public static String encode(final byte[] input) {
  		char[] chars = encode(input, input.length);
  		return new String(chars);
  	}
docs: Encodes a byte array into Base64 format. No blanks or line breaks are inserted.
  <p>
  This method has been modified to return a string not a char[].
  
  @param input an array containing the data bytes to be encoded.
  @return A character array with the Base64 encoded data.
