ed25519_sign(+KeyPair, +Data, -Signature, +Options) is det

Create an Ed25519 (RFC 8032) signature for Data with the private key of KeyPair, as created by ed25519_new_keypair/1 or obtained with load_private_key/3. Signature is a hexadecimal atom.

Options:

encoding(+Encoding): Encoding to use for Data. Default is utf8. Alternatives are octet, text and hex. Note that this differs from ecdsa_sign/4 and rsa_sign/4, which default to hex because they are typically applied to a hash of the data. Ed25519 signs the data itself.
