genpass

A simple yet robust commandline random password generator.

Multiplatform (Linux, Mac, Windows). Fast.

You can use it generate keys or passwords in scripts or use it as your primary desktop password generator.

Has extensive generative test suite, including tests against a Rust port of Dropbox's password strength tester zxcvbn

Typical usage

genpass # use defaults, they're good genpass 2048 # generate long password, can be used as a key genpass --passphrase 128 # generate longer passphrase genpass -dlu # no special characters

Generating a password directly into your system clipboard

On a Mac: genpass | pbcopy On Linux: genpass | xclip -selection clipboard

Installation

On a system with Rust installed: $ cargo install genpass

Commandline options

``` $ genpass --help

USAGE: genpass [FLAGS] [length]

FLAGS: -h, --help Prints help information -d, --include-digit Include at least one digit -l, --include-lowercase Include at least one lowercase letter -s, --include-special Include at least one special (non-alphanumeric) character -u, --include-uppercase Include at least one uppercase letter --passphrase Create a passphrase of (at least) the given length instead of a password. --version

A note on passphrases

• Passphrases are generated using EFF's "long" password list.
• Passphrases are at least --length characters long, not necessarily exactly that long.

A road to 1.0

TODOs to get genpass to 1.0

• support custom sets of characters
• add benchmarks
