Rust Password Generator is a simple and lightweight password generator written in Rust.
- Generate a random password with options to include or exclude numbers and symbols in password generation to increase password complexity.
- Generate a random PIN number with the option to configure the PIN number length.
- Analyze the security and crack time estimations of the generated password or pin number.
You will need to have Rust and Cargo installed.
# Build the project
$ cargo build --release
# Run all tests

The normal password generator mode uses a weighted distribution method, in which the weights depend on the settings enabled:
- 60% alphabets, 20% numbers, 20% symbols
- 80% alphabets, 20% numbers
- 80% alphabets, 20% symbols
- 100% alphabets
Note that in rare cases, due to the weighted distribution method, it will generate a password without numbers/symbols even though users have already enabled the enable numbers and symbols option.
-
The password security analysis and password crack time estimations uses the zxcvbn library, which is a password strength estimator through pattern matching and conservative estimation, based on Dropbox's zxcvbn library.
