= Replacing Digest::SHA1 with Digest::SHA and removal of libdigest-sha1-perl package =

<<TableOfContents>>

== Why ==
 * [[DebianBug:594273]]

Most of the functionality (except sha1_transform) of Digest::SHA1 is also provided by Digest::SHA. Switching from Digest::SHA1 to Digest::SHA should be in principle as easy as substituting the use of Digest::SHA1 with Digest::SHA.

Digest::SHA is in Perl core since version 5.9.3 and thus is in Debian's perl since Lenny.

Changing use of Digest::SHA1 to Digest::SHA would thus reduce external dependencies by one.

Packages using Digest::SHA instead of Digest::SHA1 can then drop the (Build-)Depends(-Indep) on libdigest-sha1-perl.

== How ==

 1. Investigate the Debian Perl Group packages, and forward patches to upstream authors.
 1. File bugs on non-Debian Perl Group packages too.
 1. Add lintian check for obsolete libdigest-sha1-perl dependency? [[DebianBug:635441]]
 1. increasing severity and help out where possible to fix the packages.

=== Contacting Upstream for Perl modules ===
You can use something like the following to contact upstream (in this case with patch added):
{{{
Hi                                                
                                                                   
Attached patch changes the module to use Digest::SHA instead of
Digest::SHA1. Digest::SHA is part of the standard perl distribution
since perl v5.9.3 so this reduces the number of external
dependencies by one.
         
Please consider applying it for the next release.
                                                                             
Regards,                         
}}}
