Slackware::Slackget::MD5 - A simple class to verify files checksums

Version 0.2

A simple class to verify files checksums with md5sum.

    use Slackware::Slackget::MD5;

    my $slackget10_gpg_object = Slackware::Slackget::MD5->new();

IMPORTANT NOTE : This class is not design to be use by herself (the constructor for example is totaly useless). the Slackware::Slackget::Package class inheritate of this class and this is the way is design Slackware::Slackget::MD5 : to be only an abstraction of the MD5 verification operations.

You may prefer to inheritate from this class, but take attention to the fact that I design it to be inheritate by the Slackware::Slackget::Package class !

new() : The constructor doesn't take any arguments but be sure the md5sum binary is in the PATH !

This method call the getValue() accessor (from the Slackware::Slackget::Package class) on the 'checksum' or 'signature-checksum' field, and check if it match with the MD5 of the file passed in argument.

If the argument ends with ".tgz" this method use the 'checksum' field and if it ends with ".asc" it use the 'signature-checksum' field.

	$package->verify_md5("/home/packages/update/package-cache/apache-1.3.33-i486-1.tgz") && $sgo->installpkg($packagelist->get_indexed("apache-1.3.33-i486-1")) ;

Returned values :

	undef : if a problem occur (ex: the current instance do not inheritate from Slackware::Slackget::Package, the file is not a package nor a signature, etc.)
	1 : if the MD5 is ok
	0 : if not.

This method also set a 'computed-checksum' and a 'computed-signature-checksum' in the current Slackware::Slackget::Package object.
