Functions ¶
func AddAccess ¶
func AddAccess(stub cached_stub.CachedStubInterface, startKey data_model.Key, targetKey data_model.Key, edgeData ...map[string]string) error
AddAccess gives startKey access to targetKey.
func AddAccessWithKeys ¶
func AddAccessWithKeys(stub cached_stub.CachedStubInterface, startKey []byte, startKeyId string, targetKey []byte, targetKeyId string, encKey []byte, edgeData ...map[string]string) error
(Deprecated, use AddAccess() function instead) AddAccessWithKeys gives startKey access to targetKey. It does this by encrypting targetKey with encKey, which can then be decrypted using startKey. If startKey is a sym key, encKey must be identical. Otherwise startKey must be a private key and encKey the matching public key. Stores an edge in the graph from startKeyId -> targetKeyId, and a reverse edge from targetKeyId -> startKeyId.
func ConvertKeyBytesToKey ¶
func ConvertKeyBytesToKey(keyId string, keyBytes []byte) (*data_model.Key, error)
ConvertKeyBytesToKey converts a keyId + keyBytes to a Key object
func GetAccessEdge ¶
func GetAccessEdge(stub cached_stub.CachedStubInterface, startKeyId string, targetKeyId string) ([]byte, map[string]string, error)
GetAccessEdge gets the Access key graph edge. Returns edgeValueByte, edgeDataMap, error.
func GetKey ¶
func GetKey(stub cached_stub.CachedStubInterface, keyIdList []string, startKey []byte) ([]byte, error)
GetKey follows the path of keys in keyIdList, decrypting each key along the way. When it reaches the end of the list, it returns that final key.
func GetLogSymKeyId ¶
GetLogSymKeyId returns the ID that should be assigned to a log sym key.
func GetOwnerKeys ¶
func GetOwnerKeys(stub cached_stub.CachedStubInterface, targetKeyId string, filter ...interface{}) ([]string, error)
GetOwnerKeys returns a list of keyIds which can be used to access targetKeyId (directly or indirectly).
func GetPrivateKeyHashSymKeyId ¶
GetPrivateKeyHashSymKeyId returns the ID that should be assigned to a sym key derived from the hash of a private key.
func GetPubPrivKeyId ¶
GetPubPrivKeyId returns the ID that should be assigned to a public or private key.
func GetStateByPartialCompositeKey ¶
func GetStateByPartialCompositeKey(stub cached_stub.CachedStubInterface, keys []string) (shim.StateQueryIteratorInterface, error)
func GetSymKeyId ¶
GetSymKeyId returns the ID that should be assigned to a sym key.
func GetUserKeys ¶
func GetUserKeys(stub cached_stub.CachedStubInterface, user data_model.User, filter ...interface{}) ([]string, error)
GetUserKeys returns a list of keyIds that can be accessed by the User (directly or indirectly).
func Init ¶
func Init(stub cached_stub.CachedStubInterface, logLevel ...shim.LoggingLevel) ([]byte, error)
Init sets up the key_mgmt package.
func KeyExists ¶
func KeyExists(stub cached_stub.CachedStubInterface, keyId string) bool
KeyExists checks if the key already exists in the graph, It does not check the validity of the key, only its existence in the graph.
func RevokeAccess ¶
func RevokeAccess(stub cached_stub.CachedStubInterface, startKeyId string, targetKeyId string) error
RevokeAccess revokes access from startKey to targetKey. It does this by deleting the edge from startKey -> targetKey (and the reverse edge from targetKeyId -> startKeyId).
func SlowGetMyKeys ¶
func SlowGetMyKeys(stub cached_stub.CachedStubInterface, startKeyId string, filter ...interface{}) ([]string, error)
SlowGetMyKeys returns a list of keyIds that can be accessed starting from startKeyId (directly or indirectly).
func SlowVerifyAccess ¶
func SlowVerifyAccess(stub cached_stub.CachedStubInterface, startKeyId string, targetKeyId string, filter ...interface{}) ([]string, error)
SlowVerifyAccess checks for a path in the graph from startKeyId to targetKeyId. Uses recursive DFS. Returns the list of keyIds in the path. If no path is found, returns nil.
func SlowVerifyAccessAndGetKey ¶
func SlowVerifyAccessAndGetKey(stub cached_stub.CachedStubInterface, startKeyId string, startKey []byte, targetKeyId string, filter ...interface{}) ([]byte, error)
SlowVerifyAccessAndGetKey calls FindPath and passes the result to GetKey. This is a convenience function for callers who want a key but don't want to make 2 calls. If no path is found to the targetKey, (nil, nil) is returned.
func UpdateAccessEdge ¶
func UpdateAccessEdge(stub cached_stub.CachedStubInterface, startKeyId string, targetKeyId string, edge ...interface{}) error
UpdateAccessEdge updates Access key graph edge without checking error.
func ValidateKey ¶
func ValidateKey(stub cached_stub.CachedStubInterface, key data_model.Key, mustExist bool) (bool, error)
ValidateKey checks if key matches existing key in the graph. If key does not exist, returns !mustExist. If key does exist, returns true if valid, false otherwise.
func VerifyAccessPath ¶
func VerifyAccessPath(stub cached_stub.CachedStubInterface, path []string) (bool, error)
VerifyAccessPath checks if all edges in the path exist.
func VerifyAccessPathAndGetKey ¶
func VerifyAccessPathAndGetKey(stub cached_stub.CachedStubInterface, startKeyId string, startKey []byte, path []string) ([]byte, error)
