PHP: is there a way to convert a private ECDSA key to its corresponding public key?
PHP: is there a way to convert a private ECDSA key to its corresponding public key? As described here ( http://ift.tt/1l34mjq ) I am trying to convert a private ECDSA key to its corresponding public key. (See step1 and step2). I think I need some code which multiplies some coordinates on the elliptic curve. But I dont know how. Can someone help me, please? http://ift.tt/2BzyQqK
