Struct fog_crypto::identity::UnverifiedSignature

pub struct UnverifiedSignature { /* fields omitted */ }

A signature that has been read from a byte slice but hasn’t been verified yet.

Verification can be done by getting the appropriate version of hash into the verify(...) function.

Example

let data = b"I am some test data";
// ...

let unverified = UnverifiedSignature::try_from(&encoded[..])?;
let hash_version = unverified.hash_version();
let hash = Hash::with_version(&data[..], hash_version)?;
match unverified.verify(&hash) {
    Ok(verified) => {
        println!("Got valid signature, signed by {}", verified.signer());
    },
    Err(_) => {
        println!("Signature failed validation");
    }
}
