File integrity
To check the integrity of downloaded files, one can use an MD5 hash to calculate the MD5sum of the downloaded file and compare it with a known good sum. Below is a table of known good MD5sums (the list will be fleshed out shortly):

!Filename !MD5sum
 * TWEE_Upgrade.exe (August 2011)
 * TWEE_Upgrade.exe (Bad, pre-August 2011)
 * TWEE_English_language_pack.exe
 * TWEE_adventure_The_Price_of_Neutrality.exe
 * TWEE_adventure_Side_Effects.exe
 * TWEE_Polish_language_pack.exe
 * TWEE_German_language_pack.exe

 * TWEE_Italian_language_pack.exe
 * TWEE_French_language_pack.exe
 * TWEE_Russian_language_pack.exe
 * TWEE_Hungarian_language_pack.exe
 * TWEE_Czech_language_pack.exe
 * TWEE_EAX_HotFix_2.3.exe
 * }
 * TWEE_Hungarian_language_pack.exe
 * TWEE_Czech_language_pack.exe
 * TWEE_EAX_HotFix_2.3.exe
 * }
 * TWEE_Czech_language_pack.exe
 * TWEE_EAX_HotFix_2.3.exe
 * }
 * TWEE_EAX_HotFix_2.3.exe
 * }
 * }
 * }

There are many tools that can calculate an MD5sum, for reference one can use the freely available MD5-Checksum by Nero because it lets you specify a known good MD5sum and it automatically compares it with the MD5sum calculated from your chosen file.
