Description: Directions on how to encrypt your weapon scripts and and any other file |
 ICE is the type of encryption Valve uses for scripts like the weapon scripts...Weapon script files are encrypted into a file of the extension .ctxIf you do not know the encryption key of your mod, it's probably x9Ke0BY7 (the default for HL2DM)
Why do I want to encrypt my script files?
You should encrypt your script files so they can not easily be changed by users.
To have the ability to change the weapon scripts, a mod user would have to delete the .ctx files and create the .txt files from scratch.
This makes your mod more resistant to change, which means hosted servers won't as likely have changed the weapon scripts.
How do I deal with encryption for my mod?
- Encrpyting script files
Download this file and install it into your Source SDK bin folder (C:\Program Files\[Valve]\Steam\SteamApps\[Username]\sourcesdk\bin):
Execute this in the command prompt to make the .ctx files:
"[Source SDK Bin]\vice.exe" -encrypt [Key: x9Ke0BY7 by default] -newext .ctx [.txt filenames (Use * for wildcard)]
- Changing the encryption key for your mod
To change the encryption key for your mod, you must change the returned string in the function "GetEncryptionKey" in the gamerules. The new encryption key must be eight characters long. This encryption key should be used when running vice.
- Decrypting script files
If you happen to lose your .txt files and you only have their .ctx files and your mod's encryption key, you can run vice to decrypt also:
"[Source SDK Bin]\vice.exe" -decrypt [Key: x9Ke0BY7 by default] -newext .txt [.ctx filenames (Use * for wildcard)]
Here's some defines to make your life somewhat easier if you wanna look for ctx and txt or just any specific type...
| | | #define findFiles( path, todo ) findExtFiles( path, todo, .txt );\
findExtFiles( path, todo, .ctx )
#define findExtFiles( path, todo, ext ) {\
FileFindHandle_t findHandle;\
const char *pFilename = filesystem->FindFirstEx( "##path##*##ext##", "MOD", &findHandle );\
while ( pFilename != NULL )\
{\
todo;\
}\
filesystem->FindClose( findHandle );\
}(void)0 |
then you just say
| | | findFiles(
scripts/weapons/,
char fileBase[512];
Q_FileBase( pFilename, fileBase, sizeof(fileBase) );
WEAPON_FILE_INFO_HANDLE tmp;
if ( ReadWeaponDataFromFileForSlot( filesystem, fileBase, &tmp, pICEKey ) )
gWR.LoadWeaponSprites( tmp );
pFilename = filesystem->FindNext( findHandle );
); |
but never do quotes around extensions or paths |

I see that it's near the start of CSGameRules in wordpad....
what doesnt make sense is why they have it defined as a gamerules function.....because if there are going to be multiple gamerules, they're gonna be using the same encryption key....of course if someone would want to disable a weapon in certain gamerules, they could do it this way with 100% control, (unless someone figured out the key and decrypted em all that is)Edited by ts2do on May 30 2005, 08:14:31

Pretty easy to find, actually. |
|
|
Alright, this is a really nub question, but how to you view the client.dll in wordpad? |
|
|
I am getting an error when I execute the vice program "Extra App ID set to 211, but no SteamAppId." What am I doing wrong??? Thanks for the input. |
|
|
Hey Absolute !! to answer your question... just right click on the client.dll file and chose open with and then select the program word pad. ( there may be one other step in between but can not recall at this time but I do remeber just select the bottom radio button) hope this helps.... |

Thanks ts2do !!! just one last thing. I have the file decrypted and modified for our Lan server. But there appears to be no way to re-encrypt with the new independent program. The help menue says nothing about encrypting. is the extention -e for encrypt?? The steam dependant one also does not work as would be expected. It appears that re-encryption is nessary for the game to work. Or does each computer need to have the decrypted CTX file ??? I will test that later today. Again Thanks for all your help. |

just leave -d out to encrypt... |

Sup yall
I am having a problem where i have the steam independed but it always fails to find the blasted file. anyu suggestions

Yes i did. Something apprently is when i put it in the msg board is knocks is off
ice -d -x .txt -k "" d:\program files\steam\models\weapon_ak47.ctx
"The system can not find the specified file"
I had to add the " " to make it work, it barks at me if i do not enter the key in "< key >" that format w/o the " " obviously.Edited by Unknown on Feb 08 2006, 12:01:42

the key is 8 characters long

Also call it from its folder...unless you placed it in your system folder |
