=head1 NAME

RDFStore::Util::Digest - Utility library to manage SHA-1 cryptographic digests

=head1 SYNOPSIS

	use RDFStore::Util::Digest;
	if( getDigestAlgorithm() eq 'SHA-1' ) {
		my $sha1_digest = computeDigest( $string );
		};

=head1 DESCRIPTION

Simple SHA-1 cryptographic digest generator

=over 4

=item computeDigest ( STRING )

Return binary formatted cryptographic digest of give STRING

=item getDigestAlgorithm ()

Return 'SHA-1' - no other cryto method implemented for the moment
