- VALIDATE Version 0.3
- From McAfee Associates

-
- 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.
-
- The Computer Virus Industry Association (CVIA) provides an
- online database of validation values for shareware authors at no
- cost. You are encouraged to call the CVIA's BBS at (408) 988-4004
- to access current validation data for McAfee Associates' VIRUSCAN,
- California Software Concepts' SHEZ, Vern Berg's LIST, and other
- shareware programs.
-
- 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 (less than one in
- sixty-four quadrilion) 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: (#/bytes)
- Date: (file creation date)
- File Authentication
- Check Method 1: (a four digit CRC)
- Check Method 2: (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. Please report virus infections and
- reports of program tampering to:

- The validation data for VALIDATE.COM is:
-
- WITH CRC WITHOUT
- CHECKING CHECKING
- Size: 6495 6485
- Date: 10-31-1989 10-31-1989
- File Authentication
- Check Method 1: 4637 CB21
- Check Method 2: 1214 13B7
-
- If you have an older version of VALIDATE, it may be ten (10)
- bytes shorter. This is because it was not processed by VIRUSCAN's
- CRC-checking feature, added in Version 66 of VIRUSCAN. The
- validation code can be removed from VALIDATE.COM by running
- VIRUSCAN against it with the /RV Remove Validation option.
- However, this is not recommended.
