This document enables PGP users to verify that the Anti-Vir.Dat file supplied in the distribution archive of TBAV originates from us, developers of TBAV, and has not been modified by somebody else. For information about PGP read the file ESASS.PGP and/or download the PGP package from our support BBS. If PGP has been installed and configured properly, and after you have added the ESASS.PGP public key, you can now verify the Anti-Vir.Dat file. Enter: PGP SECURITY.TXT ANTI-VIR.DAT You will see something like this: > File has signature. Public key is required to check signature. >File 'security.$00' has signature, but with no text. >Text is assumed to be in file 'anti-vir.dat'. >Good signature from user "ESaSS B.V. ". >Signature made 1996/03/27 01:52 GMT using 1024-bit key, key ID 25ADBF1D > > Signature and text are separate. No output file produced. Note that the information displayed will probably differ from this example. However, if the phrase "Good signature from user ESaSS B.V." is displayed you can be sure the file originated from ESASS. If the Anti-Vir.Dat file is verified, you can use this Anti-Vir.Dat file to find out that the executable files in the archive are unmodified too: TbScan C:\TBAV AvFile=Anti-Vir.Dat -----BEGIN PGP MESSAGE----- Version: 2.6.3i iQCVAwUANWIwJ5lbNCQlrb8dAQHaBAP7B16NuOueiG8XShWGhPM9ZwomOCIqci/u HiAB2R8Uce87+csO+Hwndm7gUwlF7HodWmnvSufEkG73p0nPR34TkBUeDCccUY/f 8QYDOu70fmzn3e/M2FERreBuJjSebiBIkHVXLV6dl1dMozOdzA0Bq9qR8jRKDmYY 2ZzgPAdoBsw= =mOFw -----END PGP MESSAGE----- 9805201221
