Sign Your Custom Maps

Use the Encryptomatic Signature app to sign modded map files.

Bungie signed each Halo 2 map with a data integrity signature. Without this signing process, a Halo 2 map will not load on the Xbox. A modder named Iron_Forge (from The Fantastic Six modding group) figured out how to create the signature and now all Halo 2 hackers can run modded Halo 2 maps on their modded Xbox consoles.

Without this ability, Halo 2 modding would not be possible. Although some people refer to this as a “security signature,” Iron_Forge believes that the intention of the signing is to verify that the file was copied properly to the Xbox hard drive (i.e., it effectively serves as an integrity checksum).

Whenever a hacker makes a change to a map, he must resign it (see Figure 6-15).
