Functions

func Prompt

func Prompt(msg string, hidden bool) (string, error)

func PromptFileName

func PromptFileName() string

func Read

func Read(prompt string, hidden bool) ([]byte, error)

Read prints the given prompt to standard output and then reads a line of input from standard input with echoing of input disabled. This is commonly used for inputting passwords and other sensitive data. The byte slice returned does not include the terminating "\n".

func ReadWithTimings

func ReadWithTimings(prompt string, timings chan<- time.Time, hidden bool) ([]byte, error)

ReadWithTimings prints the given prompt to standard output and then reads a line of input from standard input with echoing of input disabled. This is commonly used for inputting passwords and other sensitive data. The byte slice returned does not include the terminating "\n".

The time of every keypress during password input is written into the channel 'timings'. This allows to use password input to gather entropy for a random number generator. Care must be taken to not disclose these timings to an attacker: there is correlation between keys pressed and the times between key presses.
