- VALIDATE FOR OS/2
- Version 0.5
- From McAfee Associates
- (408) 988-3832
-
-
- NOTE: VALIDATE FOR OS/2 (OS2VAL.EXE) is an OS/2 V2.0-specific
- version of VALIDATE for checking files. It should be
- used to check any OS/2-based programs instead of the DOS-
- based VALIDATE.COM program.
-
- OS2VAL is a file-authentication program that may be used to
- check other programs for signs of tampering. OS2VAL uses two
- discreet 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 source. The dual CRC checking provides
- a high degree of security.
-
- To confirm that a program is in its original, untampered
- state, run the OS2VAL 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 OS2VAL, type:
-
- OS2VAL {d:\path\filename.ext}
-
- The OS2VAL 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)
-
- NOTE: The VALIDATE.COM for DOS will return a different Check
- Method 1 value for files than OS2VAL.EXE. Do not use
- VALIDATE.COM to validate OS/2 files.
-
- The OS2VAL 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:
