Module signature 

SignaturePlugin trait — the Rust-side counterpart of the asymmetric signature v0 wire protocol.

The signature interface has three object types: a signer (holds the secret key), a verifier (holds the public key), and a keypair generator. A single plugin implements all three.

Plugin authors implement this trait on a state type that represents the signer/verifier context, then apply #[plugin_interface(name = "signature", version = 0)] to the impl block.

The FFI surface splits symbols into cfmp_sig_signer_*, cfmp_sig_verifier_*, and cfmp_sig_keypair_generate. The trait methods map to these symbols.

See crates/confium-core/src/ffi/signature.rs for the loader-side wire types.

Structs

SignatureKeypair

A keypair generation result.

Traits

SignaturePlugin

Trait implemented by signature plugins. The type Self serves as both the signer and verifier state — the plugin dispatches internally based on which entry points are called.
