readpassphrase_3

Function readpassphrase

Source 
pub fn readpassphrase(prompt: &CStr, flags: RppFlags) -> Result<String, Error>
Expand description

Reads a passphrase using readpassphrase(3), returning it as a String. Internally uses a buffer of PASSWORD_LEN bytes, allowing for passwords up to PASSWORD_LEN - 1 characters (including the null terminator.)

§Security

The returned String is not cleared on success; it is the caller’s responsibility to do so, e.g.:

let pass = Zeroizing::new(readpassphrase(c"Pass: ", RppFlags::default())?);
