1The Digest::SHA1 module allows you to use the NIST SHA-1 message 2digest algorithm from within Perl programs. The algorithm takes as 3input a message of arbitrary length and produces as output a 160-bit 4"fingerprint" or "message digest" of the input. 5 6SHA1 is described at <http://www.itl.nist.gov/fipspubs/fip180-1.htm> 7 8You will need Perl version 5.004 or better to install this module. 9 10Copyright 1999-2004 Gisle Aas. 11Copyright 1997 Uwe Hollerbach. 12 13This library is free software; you can redistribute it and/or 14modify it under the same terms as Perl itself. 15
