[erlang-questions] crypto ECDSA private key -> public

[semmit mondo]

Hi, How can I generate an ECDSA public key from the private one using crypto?All I can do with it is to generate a public and private key pair at once:   {Pub, Priv} = crypto:generate_key(ecdh, prime239v3). but can't calculate the public key if the private key was known beforehand. (prime239v3 isn't important, it could be any EC curve...)
