Tink for JavaScript

[Aviva Mael]

Hi all,

I would like to use Tink in JavaScript (to be used with GooglePay). Does anyone know when that would be available? In the Tink repo it says that it is in active development. Any information would be appreciated.

Many thanks,

Aviva

We published an alpha package a while ago: https://www.npmjs.com/package/tink-crypto (sample usage). Note that this depends on WebCrypto. If you want to run it on Node.js, you'll have to install a WebCrypto shim.

 

Many thanks,

Aviva

I wonder if the Golang implementation would run in the browser via WASM. I would be interested to know if anyone has tried this yet.

You could maybe make that work, but the binary size will be huge. On my machine a basic "hello world" program using Tink for Go compiled to WebAssembly weighs in at 6.1 megabytes. If you value your users, don't send them that.

Also, I think it's using the pure-Go implementation of the crypto primitives, which is going to be both slower and more vulnerable to timing attacks than one implemented in assembly.
