Functions ¶
func CreateKeySalt ¶
CreateKeySalt derives a key and salt from a password: returns key, salt, err
func DecryptFile ¶
DecryptFile decrypts the passed ciphertext with the supplied key.
func EncryptFileData ¶
EncryptFileData encrypts the data with the supplied key
func GenerateRandomID ¶
func GenerateRandomID() string
GenerateRandomID generates a random 16 byte hex id code
func InitV1Directory ¶
InitV1Directory generates a key and salt from a password, writes a SALT and VERSION file and returns the key and salt
Types ¶
type FileStore ¶
type FileStore interface {
Write([]byte) error
Read() ([]byte, error)
Delete()
ChangeKey(newkey [32]byte)
}
FileStore is a primitive around storing encrypted files
type MessageStoreInterface ¶
type MessageStoreInterface interface {
AddMessage(groups.EncryptedGroupMessage)
FetchMessages() []*groups.EncryptedGroupMessage
MessagesCount() int
FetchMessagesFrom(signature []byte) []*groups.EncryptedGroupMessage
SetMessageCap(newcap int)
Close()
}
MessageStoreInterface defines an interface to interact with a store of cwtch messages.
type SqliteMessageStore ¶
type SqliteMessageStore struct {
// contains filtered or unexported fields
}
SqliteMessageStore is an sqlite3 backed message store
func InitializeSqliteMessageStore ¶
func InitializeSqliteMessageStore(dbfile string, messageCap int, incMessageCounterFn func()) (*SqliteMessageStore, error)
InitializeSqliteMessageStore creates a database `dbfile` with the necessary tables (if it doesn't already exist) and returns an open database
func (*SqliteMessageStore) AddMessage ¶
func (s *SqliteMessageStore) AddMessage(message groups.EncryptedGroupMessage)
AddMessage implements the MessageStoreInterface AddMessage for sqlite message store
func (*SqliteMessageStore) Close ¶
func (s *SqliteMessageStore) Close()
Close closes the underlying sqlite3 database to further changes
func (*SqliteMessageStore) FetchMessages ¶
func (s *SqliteMessageStore) FetchMessages() []*groups.EncryptedGroupMessage
FetchMessages implements the MessageStoreInterface FetchMessages for sqlite message store
func (*SqliteMessageStore) FetchMessagesFrom ¶
func (s *SqliteMessageStore) FetchMessagesFrom(signature []byte) []*groups.EncryptedGroupMessage
FetchMessagesFrom implements the MessageStoreInterface FetchMessagesFrom for sqlite message store
func (*SqliteMessageStore) MessagesCount ¶
func (s *SqliteMessageStore) MessagesCount() int
