VALIDATE Version 0.4 Copyright (C) 1989-1992 by McAfee Associates. TEL (408) 988-3832 NOTE: VALIDATE version 0.4 is being released so that VALIDATE will remain compatible with the /SAVE option of SCAN. The new /SAVE option changes the SCAN.EXE file, and the new VALIDATE will be able to compensate for the changes, so that the validation results before and after the /SAVE switch will be identical. This in no way impairs the validating process. VALIDATE is a file-authentication program that may be used to check other programs for signs of tampering. VALIDATE uses two discrete methods to generate Cyclic Redundancy Checks (CRC's), which are then displayed for the user to compare against the known value for the program(s) validated. The known validation data can be published by the author of the program or be obtained from a trusted information database. The dual CRC checking provides a high degree of security. To confirm that a program is in its original, untampered state, run the VALIDATE program on it, record the validation data produced, and compare it against the record in the online database. If they match, than it is highly improbable that the program has been modified. To run VALIDATE, type: VALIDATE d:\path\filename.ext The VALIDATE program will then display the following information: Size: Date: File Authentication Check Method 1: Check Method 2:

(#/bytes) (file creation date) (a four digit CRC) (a four digit CRC)

The VALIDATE program may be copied and distributed at no charge as long as it is distributed whole and intact and unmodified in any way, along with this file.
