# A CSPRNG for TinyGo/WebAssembly (WASI)

TinyGo doesn't support `crypto/rand` yet, which is quite of a deal breaker for many cryptographic operations.

This module implements `wasi_rand`, a secure random number generator for TinyGo when used in a WebAssembly/WASI environment.

Usage:

```go

import (

    wasi_rand "github.com/jedisct1/tinygo-wasi_rand"

)

func main() {

    var key [32]byte

    if err := wasi_rand.Read(key[:]); err != nil {

        // panic: no entropy source available

    }

}

```

`wasi_rand.Read()` can fill buffers of arbitrary sizes.
