Functions

func CheckTrailingGarbage

func CheckTrailingGarbage()

CheckTrailingGarbage tries to read one byte from stdin and exits with a fatal error if the read returns any data. This is meant to be called after reading the password, when there is no more data expected. This helps to catch problems with third-party tools that interface with gocryptfs.

This is tested via TestInitTrailingGarbage() in tests/cli/cli_test.go.

func Once

func Once(extpass string) []byte

Once tries to get a password from the user, either from the terminal, extpass or stdin.

func Twice

func Twice(extpass string) []byte

Twice is the same as Once but will prompt twice if we get the password from the terminal.
