+.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:
+.Bl -tag -width indent
+.It Fl a Ar algorithm
+When invoked as
+.Nm cksum ,
+use the specified
+.Ar algorithm .
+Valid algorithms are:
+.Bl -column -offset indent ".Sy Algorithm" ".Sy Bits" ".Sy Description"

+.It Li old1 Ta 16 Ta Algorithm 1, per Fl o Ar 1
+.It Li old2 Ta 16 Ta Algorithm 2, per Fl o Ar 2
+.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.
+.Ed
+.Pp
+The
+.Nm
+and
+.Nm sum
+utilities exit 0 on success, and \*[Gt]0 if an error occurs.
