Protect

Tag Info
Tag Number: 
24
Tag Type: 
Define
Tag Flash Version: 
2
Brief Description: 

Disable edition capabilities of the given SWF file. Though this doesn't need to be enforced by an SWF editor, it marks the file as being copyrighted in a way.

WARNING: this tag is only valid in Flash V2.x, V3.x, and V4.x, use the EnableDebugger instead in V5.x and EnableDebugger2 in V6.x and newer movies.

Tag Structure: 
struct swf_protect {
	swf_tag			f_tag;		/* 24, 58 or 64  */
	if(version >= 5) {
		if(tag == ProtectDebug2) {
			unsigned short	f_reserved;1
		}
		/* the password is optional when tag == Protect */
		string		f_md5_password;
	}
};
  • 1. f_reserved must be set to zero.

The protection tag is totally useless. The SWF format is an open format, otherwise how would you have so many players and tools to work with SWF movies? Thus, you can pretend to protect your movies, but anyone with a simple binary editor can transform the tag and make it another which has no such effect. Also, swf_dump and some other tools (such as flasm) can read your movie anyway.

For the sake of defining what you have in each tag, there are the protection tags fully described.

File Header

Tag Info
Tag Number: 
-1
Tag Type: 
Format
Tag Flash Version: 
1
Brief Description: 

Although it isn't a tag per say, we consider the file header as being a tag because it represents a block in the flash file. Since version 8, it can be complemented by the FileAttributes tag.

Tag Structure: 
struct swf_header {1
	unsigned char		f_magic[3];	/* 'FWS' or 'CWS' */
	unsigned char		f_version;
	unsigned long		f_file_length;
}

struct swf_header_movie {2
	swf_rect		f_frame_size;
	unsigned short fixed	f_frame_rate;
	unsigned short		f_frame_count;
};
  • 1. This part is never compressed
  • 2. Although considered part of the header, this part is compressed in the 'CWS' format.

The file header is found at the very beginning of the file. It should be used to determine whether a file is an SWF file or not. Also, it contains information about the frame size, the speed at which is should be played and the version (determining the tags and actions possibly used in the file).

The f_magic[3] array is defined as the characters: 'FWS' (it is going backward probably because it was supposed to be read in a little endian as a long word). A movie can be compressed when the version is set to 6 or more. In this case, the magic characters are: 'CWS'.

LinuxWorld Conference & Expo 2008

This year, 2008, I decided to register and go to LinuxWorld. It is in August and my kids are not at school so it was easy to manage. Also, I had to go to the French consulate to get a birth certificate for my daughter. In other words, I had the chance to do two things at once!

I found it quite interesting to hear that many people were not too excited about the event. Many of the people walking around are like me: they themselves sell their own Linux solution. In other words, they are not going to be customers. I had the chance to talk with Roger Levi, the Vice President of the Open Platform ...
