Are Steam files signed with unique ID of the buyer ?

[heroskeep]

I want to create torrent from Steam purchased game but I'm worried if the files are signed with some unique ID that will lead to my Steam account.

If anyone know if this files are signed somehow please let me know, I don't know if other uploaders are stripping those files from ID's / buying from fake accounts or if there aren't any signing.

I don't want my Steam account to be banned or to be chased by copyright trolls.

Thank You

I have found one file that is definitely signed:

appmanifest.acf

when I open it with notepad there is one suspicious line:

"LastOwner" "SOME LONG NUMBER HERE"

I will change this number to some other, If someone got hints on this, please reply.

Thank You
