Module sodoken::sign

Api functions related to cryptographic signatures and verification.

Example

// we have a keypair
let pk: sodoken::BufWriteSized<{ sodoken::sign::PUBLICKEYBYTES }> =
    sodoken::BufWriteSized::new_no_lock();
let sk: sodoken::BufWriteSized<{ sodoken::sign::SECRETKEYBYTES }> =
    sodoken::BufWriteSized::new_mem_locked().unwrap();
sodoken::sign::keypair(pk.clone(), sk.clone()).await.unwrap();
let pk = pk.to_read_sized();
let sk = sk.to_read_sized();

// we can generate a signature
let sig: sodoken::BufWriteSized<{ sodoken::sign::BYTES }> =
    sodoken::BufWriteSized::new_no_lock();
sodoken::sign::detached(
    sig.clone(),
    b"test message".to_vec(),
    sk,
).await.unwrap();
let sig = sig.to_read_sized();

// we can validate the signature
assert!(sodoken::sign::verify_detached(
    sig,
    b"test message".to_vec(),
    pk,
).await.unwrap());
