Constructors in ch.epfl.dedis.lib.darc with parameters of type Signer

Constructor and Description
Darc(Signer owner, List<Signer> users, byte[] data) Overloaded function for convenience.
DarcSignature(byte[] msg, Darc darc, Signer signer, int role)
DarcSignature(byte[] msg, SignaturePath path, Signer signer) This will return a new DarcSignature by the signer on the message.
IdentityEd25519(Signer signer) Creates an IdentityEd25519 from a SignerEd25519.
IdentityX509EC(Signer signer) Creates an IdentityEd25519 from a SignerEd25519.
SignaturePath(Darc darc, Signer signer, int role) Overloaded method for convenience.
SignaturePath(List<Darc> darcPath, Signer signer, int role) Overloaded method for convenience.
SignaturePath(Signer signer, int role) For creating online paths that don't inlcude the previous darcs but that need the path to be verified by the verifier itself.

Uses of Signer in ch.epfl.dedis.ocs

Methods in ch.epfl.dedis.ocs with parameters of type Signer

Modifier and Type	Method and Description
Darc	OnchainSecrets.addIdentityToDarc(Darc darc, Identity identity, Signer signer, int role) Adds a new identity to an existing darc under the given role.
Darc	OnchainSecrets.addIdentityToDarc(DarcId id, Signer identity, Signer signer, int role) Instead of giving a darc, this method will search for an existing darc given its id on the skipchain.
Darc	OnchainSecrets.addIdentityToDarc(Darc darc, Signer identity, Signer signer, int role) Overloaded method for convenience in case the identity is only available as a signer.
SignaturePath	OnchainSecrets.getDarcPath(DarcId base, Signer identity, int role) Convenience method to pass a signer as identity and get the darc-path used in signatures.
Document	OnchainSecrets.getDocument(WriteRequestId wrId, Signer reader) Creates a read-request, if successful fetches the document from the skipchain and decodes the keymaterial.
Document	OnchainSecrets.getDocumentEphemeral(WriteRequestId wrId, Signer reader) Requests the re-encryption symmetricKey from the skipchain, but uses an ephemeral key for it.
DarcSignature	WriteRequest.getSignature(OnchainSecretsRPC ocs, Signer publisher) Creates a correct signature-path starting from the admin darc and signs that path to get a correct write-request.
WriteRequest	OnchainSecrets.publishDocument(Document doc, Signer writer) Publishes a document given the Document and the writer with write-authorization.
Darc	OnchainSecrets.removeIdentityFromDarc(Darc darc, Identity identity, Signer signer, int role) Remove identity from an existing darc under the given role.

Constructors in ch.epfl.dedis.ocs with parameters of type Signer

Constructor and Description
ReadRequest(OnchainSecretsRPC ocs, WriteRequestId wrId, Signer reader) This fetches the write-request and the path for the reader to sign.
