Struct ValidatableEd25519Signature

pub struct ValidatableEd25519Signature {
    key: PublicKey,
    sig: Signature,
    entire_text_of_signed_thing: Vec<u8>,
}

An ed25519 signature, plus the document that it signs and its public key.

Fields

key: PublicKey

The key that allegedly produced the signature

sig: Signature

The alleged signature

entire_text_of_signed_thing: Vec<u8>

The entire body of text that is allegedly signed here.

TODO: It’s not so good to have this included here; it would be better to have a patch to ed25519_dalek to allow us to pre-hash the signed thing, and just store a digest. We can’t use that with the ‘prehash’ variant of ed25519, since that has different constants.
