Function ed25519_dalek::hazmat::raw_sign

source · 
pub fn raw_sign<CtxDigest>(
    esk: &ExpandedSecretKey,
    message: &[u8],
    verifying_key: &VerifyingKey,
) -> Signature
where
    CtxDigest: Digest<OutputSize = U64>,
Expand description

Compute an ordinary Ed25519 signature over the given message. CtxDigest is the digest used to calculate the pseudorandomness needed for signing. According to the Ed25519 spec, CtxDigest = Sha512.

§⚠️ Unsafe

Do NOT use this function unless you absolutely must. Using the wrong values in ExpandedSecretKey can leak your signing key. See here for more details on this attack.
