[Return to contents]

generate_key

fn generate_key() !(PublicKey, PrivateKey)

generate_key generates a public/private key pair entropy using crypto.rand.

[Return to contents]

new_key_from_seed

fn new_key_from_seed(seed []u8) PrivateKey

sign

fn sign(privatekey PrivateKey, message []u8) ![]u8

sign`signs the message with privatekey and returns a signature

[Return to contents]

verify

fn verify(publickey PublicKey, message []u8, sig []u8) !bool

verify reports whether sig is a valid signature of message by publickey.

[Return to contents]
