Calculates 32-bit CRC.

Full Description of File


XSUM V1.1 Checksumming utility suite
---------------------------------------
Calculates the 32-bit CRC and the MD4
and MD5 message digests of files and
displays them along with the file size,
time, and date. MD5 calculation is
much faster than in the previous
release. Contains mdx version 1.05
and crc version 1.07.

The XSUM package of checksum utilities is FreeWare from David R. Conrad
consisting of the following files:

README This file
WHATSNEW Some notes on the differences from previous versions.
FILE_ID.DIZ A brief description of the package.
XSUM.MAN The manual, formatted (suitable for printing).
XSUM.DOC The manual in `plain ASCII' form.
CRC.EXE Program which generates 32-bit CRCs of files.
MDX.EXE Program which generates MD4 and MD5 message digests.

This package may be used and distributed freely as long as no changes
are made, all files are distributed, and no more than a nominal fee is
charged for distribution.

No guarantees are made, but you may send bug reports to the author by
any of the ways described in the manual or at the address below.

The formatted version of the manual contains overstriking to produce
bold and underlined text. This will look good on a printer or a smart
pager such as less, or even with the type or more commands. But if it
doesn't look good, try the plain ASCII version, which contains no
special characters other than formfeeds.

A note on viruses: The programs have been pronounced clean by F-Prot
2.16, and CatchMte 1.8. My thanks to Fridrik Skulason of Frisk
Software, and Tarkan Yetiser of the VDS Advanced Research Group.
The programs will refuse to run if they are infected with a
non-stealth file infecting virus.

A note on checksums: CRC is intended for error detection. It is not
suitable for authentication or validation since it is trivial to forge.
MD4 and MD5, however, are `one-way' hash functions. It is asserted
that it is computationally infeasible to create a file with a specific
message digest.

MD4 and MD5 refer to The RSA Data Security, Inc. MD4 Message-Digest
Algorithm and The RSA Data Security, Inc. MD5 Message-Digest Algorithm.
