pas

A random passphrase generator using indonesian wordlist.

Notes

This is only used for poc to generate random passphrase based on @geovedi's indonesian-wordlist dataset using rand crates.

Also, for now the 05-ivanlanin2011-sort-alpha.lst file (dataset) is required to live in cwd to make this program works. In future, we'll embed the files (~156K) into program at compile-time.

Development

Clone this repository, run cargo run, that's it.

Wasi

If you want build the project as Wasm in WASI format, first of all:

You need to add wasm32-wasi as the build target:

rustup target add wasm32-wasi

And then build the project for that target:

cargo build --target wasm32-wasi

Verify the build by using this command:

$ file target/wasm32-wasi/debug/pas.wasm
target/wasm32-wasi/debug/pas.wasm: WebAssembly (wasm) binary module version 0x1 (MVP)

If the output similar with above, your wasm module is ready to use.

This is the example using wasmtime runtime.

$ wasmtime --version
0.7.0

$ wasmtime --dir=. target/wasm32-wasi/debug/pas.wasm
kedai kasur meringkus mukjizat bergegas miris kliyengan melarat peradaban menggerumit intuisi jujur

Pretty good.

Btw, this is just for fun (unoptimized build):
