Background

This repository exists in order to provide easy functional testing for shssoichiro/zxcvbn-rs#83

Prerequisites

• Go toolchain
• Rust toolchain
• wasm-objdump and wasm-snip: see installation instructions

Testing environment

This project is made of two components:

• core, a Rust WASM library that calls the zxcvbn function of the zxcvbn crate. It exposes a function strength_for_password consuming a string, and returns the guesses_log10 attribute of its entropy.
• client, a Go app consuming the WASM-compiled core. It injects the unix_time_milliseconds_imported in the environment, which is called within the zxcvbn library, imported in core's Cargo.toml with the custom_wasm_env feature on.

Testing steps

From the root of the repository, run

make run

This should output the entropy score of the PASSWORD_TO_TEST var defined in client/main.go.

Not injecting the function, or importing the crate without the custom_wasm_env will result in errors.
