RDF::Crypt::Role::DoesSign - signing methods
Given an RDF::Trine::Model, returns a signature as a string.
The model is converted to a canonicalised N-Triples representation (see RDF::Trine::Serializer::NTriples::Canonical) with any triples that cannot be canonicalised being truncated. This representation is then signed using an MD5 digest, and the resulting binary signature encoded using base64.
Given a WebID that people can use to recover your public key, and a list of URLs that need signing, signs each and returns an RDF::Trine::Model containing the results of processing. This can be serialised as, say, Turtle to act as an endorsement for a bunch of RDF graphs.
Parses the given Turtle into a model, generates a signature for that and then returns the original Turtle with the signature embedded as a comment. This allows the signature to sit in the same file as the data itself.
The base URI is used to resolve any relative URI references. Note that if a different base URI is provided when verifying the signature, this may cause verification to fail. The base URI is optional.
sign_embed_turtle, but RDF/XML.
sign_embed_rdfa($html, $baseuri, \%config)
sign_embed_rdfxml. The base URI is required. A set of configuration options may be provided, which will be passed along to RDF::RDFa::Parser's constructor.
Rather than storing the signature as an XML/HTML comment, the signature is stored on the root element as an attribute.
Signs a literal string which may or may not have anything to do with RDF.
This role does not implement these methods, but requires classes to implement them instead:
Generates a signature for an octet string.
Returns a string used as a marker for signatures within serialised RDF.
