Uncaught __dir__ while trying to generate a SubtleCrypto.generateKey()

[BobSquarePants]

Hi,

in my brython file II've tried the following

def successCallback(result):
	print('so far so good')  

window.crypto.subtle.generateKey(
	{'name':'ECDSA','namedCurve':'P-256'},
	True,
	["encrypt", "decrypt"]).then(successCallback)

But I got, in the DOM console

Uncaught dir:

Any ideas ?

info: https://developer.mozilla.org/en-US/docs/Web/API/SubtleCrypto/generateKey

Thanks

Brython: 3.11.2

I've updated my code with a try except

and I got

'Javascript Crypto' object has no attribute 'subtle'

an on MDN we can read:

This feature is available only in secure contexts (HTTPS)...

and I make obviously my test in local so in HTTP. so no access to subtle 😬

TBC

I confirm, the error was happening because SubtleCrypto is only available in HTTPS...

Anyway, making some test with the method of SubtleCrypto
it make me almost puke... They have made it complex for no reason ! (when I compare the same function in 🐍 Python, damn it so much easier, readable, make sense !)

//The minimum to generate a hash and print it !!! 🤮 
const sha256 = async (data) => {
    const textAsBuffer = new TextEncoder().encode(data);
    const hashBuffer = await window.crypto.subtle.digest('SHA-256', textAsBuffer);
    const hashArray = Array.from(new Uint8Array(hashBuffer))
    const digest = hashArray.map(b => b.toString(16).padStart(2, '0')).join('');
    return digest;
}
const textToHash = "myData";
const hash = await sha256(textToHash);
console.log(hash);

So I will do the necessary on the server side ¯\(ツ)/¯ with our beloved 🐍 Python.
