.Sh DESCRIPTION
|
||||||
|
The
|
||||||
|
.Nm
|
||||||
|
utility writes to the standard output three whitespace separated
|
||||||
|
fields for each input file.
|
||||||
|
These fields are a checksum
|
||||||
|
.Tn CRC ,
|
||||||
|
the total number of octets in the file and the file name.
|
||||||
|
If no file name is specified, the standard input is used and no file name
|
||||||
|
is written.
|
||||||
|
.Pp
|
||||||
|
The
|
||||||
|
.Nm sum
|
||||||
|
utility is identical to the
|
||||||
|
.Nm
|
||||||
|
utility, except that it defaults to using historic algorithm 1, as
|
||||||
|
described below.
|
||||||
|
It is provided for compatibility only.
|
||||||
|
.Pp
|
||||||
|
The
|
||||||
|
.Nm md2 ,
|
||||||
|
.Nm md4 ,
|
||||||
|
.Nm md5 ,
|
||||||
|
.Nm sha1 ,
|
||||||
|
and
|
||||||
|
.Nm rmd160
|
||||||
|
utilities compute cryptographic hash functions, and write to standard
|
||||||
|
output the hexadecimal representation of the hash of their input.
|
||||||
|
.Pp
|
||||||
|
The options are as follows:

|
||||||
|
.El
|
||||||
|
.It Fl c Op Ar sumfile
|
||||||
|
Verify (check) files against a list of checksums.
|
||||||
|
The list is read from
|
||||||
|
.Ar sumfile ,
|
||||||
|
or from stdin if no filename is given.
|
||||||
|
E.g. first run
|
||||||
|
.Dl Ic md5 *.tgz \*[Gt] MD5
|
||||||
|
.Dl Ic sha1 *.tgz \*[Gt] SHA1
|
||||||
|
to generate a list of MD5 checksums in
|
||||||
|
.Pa MD5 ,
|
||||||
|
then use the following command to verify them:
|
||||||
|
.Dl Ic cat MD5 SHA1 | cksum -c
|
||||||
|
If an error is found during checksum verification, an error
|
||||||
|
message is printed, and the program returns an error code of 1.
|
||||||
|
.It Fl o
|
||||||
|
Use historic algorithms instead of the (superior) default one.
|
||||||
|
.Pp
|
||||||
|
Algorithm 1 is the algorithm used by historic
|
||||||
|
.Bx
|
||||||
|
systems as the
|
||||||
|
.Xr sum 1
|
||||||
|
algorithm and by historic
|
||||||
|
.At V
|
||||||
|
systems as the
|
||||||
|
.Xr sum 1
|
||||||
|
algorithm when using the
|
||||||
|
.Fl r
|
||||||
|
option.
|
||||||
|
This is a 16-bit checksum, with a right rotation before each addition;
|
||||||
|
overflow is discarded.
|
||||||
|
.Pp
|
||||||
|
Algorithm 2 is the algorithm used by historic
|
||||||
|
.At V
|
||||||
|
systems as the
|
||||||
|
default
|
||||||
|
.Xr sum 1
|
||||||
|
algorithm.
|
||||||
|
This is a 32-bit checksum, and is defined as follows:
|
||||||
|
.Bd -unfilled -offset indent
|
||||||
|
s = sum of all bytes;
|
||||||
|
r = s % 2^16 + (s % 2^32) / 2^16;
|
||||||
|
cksum = (r % 2^16) + r / 2^16;
|
||||||
|
.Ed
|
||||||
|
.Pp
|
||||||
|
Both algorithm 1 and 2 write to the standard output the same fields as
|
||||||
|
the default algorithm except that the size of the file in bytes is
|
||||||
|
replaced with the size of the file in blocks.
|
||||||
|
For historic reasons, the block size is 1024 for algorithm 1 and 512
|
||||||
|
for algorithm 2.
|
||||||
|
Partial blocks are rounded up.
|
||||||
|
.It Fl w
|
||||||
|
Print warnings about malformed checksum files when verifying
|
||||||
|
checksums with
|
||||||
|
.Fl c .
|
||||||
|
.El
|
||||||
|
.Pp
|
||||||
|
The following options apply only when using the one of the message
|
||||||
|
digest algorithms:
|
||||||
|
.Bl -tag -width indent
|
||||||
|
.It Fl n
|
||||||
|
Print the hash and the filename in the normal sum output form, with
|
||||||
|
the hash at the left and the filename following on the right.
|
||||||
|
.It Fl p
|
||||||
|
Echo input from standard input to standard output, and append the
|
||||||
|
selected message digest.
|
||||||
|
.It Fl s Ar string
|
||||||
|
Print the hash of the given string
|
||||||
|
.Ar string .
|
||||||
|
.It Fl t
|
||||||
|
Run a built-in message digest time trial.
|
||||||
|
.It Fl x
|
||||||
|
Run a built-in message digest test script.
|
||||||
|
The tests that are run
|
||||||
|
are supposed to encompass all the various tests in the suites that
|
||||||
|
accompany the algorithms' descriptions with the exception of the
|
||||||
|
last test for the SHA-1 algorithm and the RIPEMD-160 algorithm.
|
||||||
|
The
|
||||||
|
last test for these is one million copies of the lower letter a.
|
||||||
|
.El
|
||||||
|
.Pp
|
||||||
|
The default
|
||||||
|
.Tn CRC
|
||||||
|
used is based on the polynomial used for
|
||||||
|
.Tn CRC
|
||||||
|
error checking
|
||||||
|
in the networking standard
|
||||||
|
.St -iso8802-3 .
|
||||||
|
The
|
||||||
|
.Tn CRC
|
||||||
|
checksum encoding is defined by the generating polynomial:
|
||||||
|
.Pp
|
||||||
|
.Bd -unfilled -offset indent
|
||||||
|
G(x) = x^32 + x^26 + x^23 + x^22 + x^16 + x^12 +
|
||||||
|
x^11 + x^10 + x^8 + x^7 + x^5 + x^4 + x^2 + x + 1
|
||||||
|
.Ed
|
||||||
|
.Pp
|
||||||
|
Mathematically, the
|
||||||
|
.Tn CRC
|
||||||
|
value corresponding to a given file is defined by
|
||||||
|
the following procedure:
|
||||||
|
.Bd -filled -offset indent
|
||||||
|
The
|
||||||
|
.Ar n
|
||||||
|
bits to be evaluated are considered to be the coefficients of a mod 2
|
||||||
|
polynomial M(x) of degree
|
||||||
|
.Ar n Ns \-1 .
|
||||||
|
These
|
||||||
|
.Ar n
|
||||||
|
bits are the bits from the file, with the most significant bit being the most
|
||||||
|
significant bit of the first octet of the file and the last bit being the least
|
||||||
|
significant bit of the last octet, padded with zero bits (if necessary) to
|
||||||
|
achieve an integral number of octets, followed by one or more octets
|
||||||
|
representing the length of the file as a binary value, least significant octet
|
||||||
|
first.
|
||||||
|
The smallest number of octets capable of representing this integer are used.
|
||||||
|
.Pp
|
||||||
|
M(x) is multiplied by x^32 (i.e., shifted left 32 bits) and divided by
|
||||||
|
G(x) using mod 2 division, producing a remainder R(x) of degree \*[Le] 31.
|
||||||
|
.Pp
|
||||||
|
The coefficients of R(x) are considered to be a 32-bit sequence.
|
||||||
|
.Pp
|
||||||
|
The bit sequence is complemented and the result is the CRC.

||||||

|
The
|
||||||
|
.Nm
|
||||||
|
and
|
||||||
|
.Nm sum
|
||||||
|
utilities exit 0 on success, and \*[Gt]0 if an error occurs.
