The "good-enough" password generator ¯\(ツ)/¯
passt is a "zero-dependency" random string generator that can be used to generate passwords in terminals or in your application.
- Zero Dependencies? - Supported operating systems - *nix - Windows Support - Usage: library - Usage: cli - Known issues - Emoji support - Why the name "passt" - License
passt only depends on Rust standard library, namely:
- std::fs::File
- std::io::Read
and additionally for the CLI part:
- std::env
and no other crates.
The only other "dependency" is /dev/urandom from which random ints are read to generate random values. So "zero-dependency" may be a bit of a stretch. 😬
All GNU/Linux / *nix systems should be supported as long as they have /dev/urandom. Only tested on MacOS and Ubuntu.
For Windows file:/dev/urandom is read but this is not yet tested. It may or may not work. 🤷♀️ Help with Windows support is appreciated!
Use the standard character sets. This means possible characters are:
- a-zA-Z0-9 if no special chars are included
- a-zA-Z0-9 and !§$%&/()=?´-_.,:;#'+*<>°^ if special chars are included
```rust use passt:Passt;
fn myrandompassword() -> String {
// Passt::randompassword(length: i32, withspecialchars: Option
fn myrandompasswordwithnone() -> String {
// Passt::randompassword(length: i32, withspecialchars: Option
fn myrandompasswordwithspecialchars() -> String { Passt::randompassword(16, Some(true)); } ```
Specify custom character set
This allows you to use a different set of possible characters.
rust
fn my_custom_set() {
// Create password only from random chars "acefhjlnprtvxz13579"
Pass::random_password_with_custom_set(16, "acefhjlnprtvxz13579")
}
```bash
USAGE: passt -l
-l length of the generated password -s use special characters ```
```bash $ passt -l 16 -s D#§2§RgI0Ou°F#
$ passt -l 32 OgHFnTrSH5liCPhkrfbHdfhSWFwGGAPA ```
Right now the generation does not work with a string of emojis. This must have to do with the way the random characters are extracted.
"passt" is a German word you can say if something is "okay". Since this tool is "okay" in generating random strings that can be used for passwords I found the name fitting.
