Available on crate feature hazmat only.
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.
