added in this version, taken from the reference code from the NESSIE
project. Passes regression test suite on NetBSD/{i386,sparc64} and
also on SunOS 5.9 sparc (thanks, Jonathan).

|
.Ar algorithm
|

|
|
.Sh DESCRIPTION
|
|
The
|
|
.Nm
|
|
utility calculates message digests of files or,
|
|
if no file is specified, standard input.
|
|
The list of possible algorithms is:
|
|
.Bl -tag -width Ds
|
|
.It md5
|
|
the
|
|
.Xr md5 3
|
|
algorithm will be used.
|
|
.It rmd160
|
|
the
|
|
.Xr rmd160 3
|
|
algorithm will be used.
|
|
.It sha1
|
|
the
|
|
.Xr sha1 3
|
|
algorithm will be used.
|
|
.It sha256
|
|
the
|
|
sha256
|
|
algorithm will be used.
|
|
.It sha384
|
|
the
|
|
sha384
|
|
algorithm will be used.
|
|
.It sha512
|
|
the
|
|
sha512
|
|
algorithm will be used.
|
|
.It tiger
|
|
the
|
|
tiger
|
|
algorithm will be used.
|
|
.It whirlpool
|
|
the
|
|
whirlpool
|
|
algorithm will be used.
|
|
.El
|
|
.Pp
|
|
The
|
|
.Nm
|
|
utility is a simple wrapper for the various different
|
|
algorithm implementations, which are located in the standard
|
|
C library, and was designed to be scalable as new message digest
|
|
algorithms are developed.
|
|
.Pp
|
|
The
|
|
.Nm
|
|
utility exits 0 on success, and \*[Gt]0 if an error occurs.
