=head1 NAME

shasum - Print or Check SHA Checksums

=head1 SYNOPSIS

Usage: shasum [OPTION] [FILE]...
    or: shasum [OPTION] --check [FILE]
 Print or check SHA checksums.
 With no FILE, or when FILE is -, read standard input.

-a, --algorithm    1 (default), 224, 256, 384, 512
  -b, --binary       read files in binary mode (default on DOS/Windows)
  -c, --check        check SHA sums against given list
  -p, --portable     read files in portable mode
                         produces same digest on Windows/Unix/Mac
  -t, --text         read files in text mode (default)

The following two options are useful only when verifying checksums:

-s, --status       don't output anything, status code shows success
  -w, --warn         warn about improperly formatted SHA checksum lines

-h, --help         display this help and exit
  -v, --version      output version information and exit

The sums are computed as described in FIPS PUB 180-2.  When checking,
 the input should be a former output of this program.  The default mode
 is to print a line with checksum, a character indicating type (`*'
 for binary, `?' for portable, ` ' for text), and name for each FILE.

=head1 DESCRIPTION

The I<shasum> script provides the easiest and most convenient way to
compute SHA message digests.  Rather than writing a program, the user
simply feeds data to the script via the command line, and waits for
the results to be printed on standard output.  Data can be fed to
I<shasum> through files, standard input, or both.

The following command shows how easy it is to compute digests for typical
inputs such as the NIST test vector "abc":

perl -e "print qw(abc)" | shasum

Or, if you want to use SHA-256 instead of the default SHA-1, simply say:

perl -e "print qw(abc)" | shasum -a 256

Since I<shasum> uses the same interface employed by the familiar
I<sha1sum> program (and its somewhat outmoded anscestor I<md5sum>),
you can install this script as a convenient drop-in replacement.

shasum is implemented using the Perl module L<Digest::SHA> or
L<Digest::SHA::PurePerl>.
