The user simply feeds data to the script through files or +standard input, and then collects the results from standard output. +.PP +The following command shows how to compute digests for typical inputs +such as the NIST test vector "abc": +.PP +.Vb 1 +\& perl \-e "print qq(abc)" | shasum +.Ve +.PP +Or, if you want to use SHA\-256 instead of the default SHA\-1, simply say: +.PP +.Vb 1 +\& perl \-e "print qq(abc)" | shasum \-a 256 +.Ve +.PP +Since \fIshasum\fR mimics the behavior of the combined GNU \fIsha1sum\fR, +\&\fIsha224sum\fR, \fIsha256sum\fR, \fIsha384sum\fR, and \fIsha512sum\fR programs, +you can install this script as a convenient drop-in replacement. +.PP +Unlike the GNU programs, \fIshasum\fR encompasses the full SHA standard by +allowing partial-byte inputs. This is accomplished through the BITS +option (\fI\-0\fR). The following example computes the SHA\-224 digest of +the 7\-bit message \fI0001100\fR: +.PP +.Vb 1 +\& perl \-e "print qq(0001100)" | shasum \-0 \-a 224 +.Ve +.SH AUTHOR +.IX Header "AUTHOR" +Copyright (C) 2003\-2023 Mark Shelor <mshelor@cpan.org>. +.SH "SEE ALSO" +.IX Header "SEE ALSO" +\&\fIshasum\fR is implemented using the Perl module Digest::SHA. |
