@ingroup crypto Derive a public key from a given public key and a label. Essentially calculates a public key ‘V = H(l,P) * P’.

@param pub original public key @param label label to use for key deriviation @param context additional context to use for HKDF of ‘h’. typically the name of the subsystem/application @param result where to write the derived public key
