3.1.1.3.5 SetUserKeyPair
SetUserKeyPair stores a key pair for a specified account in internal or external storage so that it can be retrieved by GetUserKeyPair. An implementation can choose not to store these key pairs, in which case a new key pair is generated each time it is needed. In this case, each RAC belonging to the user has a different key, so ULs issued to the user will work only with the RAC that was used to request the UL. The interface takes two parameters: account of type string and keyPair, an asymmetric key pair. The interface does not have a return value.
