[comp.binaries.ibm.pc.d] SEA's ARC522.EXE - how to check other copies

W8SDZ@SIMTEL20.ARPA (Keith Petersen) (07/27/88)

The ARC522.EXE available from SIMTEL20 is authentic, having been
obtained directly from SEA's BBS.  If you find a copy of it on your
local BBS here's how to check to make sure it is authentic.

After running ARC522.EXE to extract its files you should see:

ARCE     COM     7136   9-16-87   3:12a
ARC      DOC   103359   3-31-88   5:22p
ARC      EXE    32706   3-23-88   3:22p
ARCE     DOC    11373   9-16-87   3:12a
ARCORDER TXT     4309   3-31-88   5:14p

Using CRC67, a CRC checking program, to check the files you should see:

--> FILE:  ARCE    .COM		CRC = D0 6A
--> FILE:  ARC     .DOC		CRC = 45 FD
--> FILE:  ARC     .EXE		CRC = 85 68
--> FILE:  ARCE    .DOC		CRC = 9E D8
--> FILE:  ARCORDER.TXT		CRC = A1 9C

If you don't have CRC67, use the new ARC.EXE to make an archive of the
extracted files.  The archive should look like this (note the CRCs and
file sizes).
