=head1 NAME

OAuth::Lite2::Signer::Algorithms - signature algorithms

=head1 SYNOPSIS

    my $algorithm = OAuth::Lite2::Signer::Algorithms->get_algorithm('hmac-sha256');
    my $signature = $algorithm->hash($key, $text);

=head1 DESCRIPTION

DEPRECATED. algorithm object store for OAuth 2.0 signature.

=head1 METHODS

=head2 add_algorithm( $signer )

Add signer algorithm object. the class should be L<OAuth::Lite2::Signer::Algorithm> or its child.
L<OAuth::Lite2::Signer::Algorithm::HMAC_SHA256> is automatically added by default.

=head2 get_algorithm( $algorithm_name )

Get algorithm object by its name.

    my $algorithm = OAuth::Lite2::Signer::Algorithms->get_algorithm('hmac-sha256');
