crypto: adjust types for getRandomValues #41481

LiviaMedeiros · 2022-01-11T17:15:46Z

Prevents Web Crypto API's getRandomValues from accepting DataView

WIP/draft at this moment.

I'm not sure if new DataView(buf.buffer) in this test was intentional:

node/test/parallel/test-webcrypto-random.js

Lines 47 to 53 in 6b7b0b7

    
           { 
        
             const buf = new Uint16Array(10); 
        
             const before = Buffer.from(buf).toString('hex'); 
        
             getRandomValues(new DataView(buf.buffer)); 
        
             const after = Buffer.from(buf).toString('hex'); 
        
             assert.notStrictEqual(before, after); 
        
           }

@LiviaMedeiros If this is ready (it seems so) please remove the draft status, otherwise CI does not run. Thank you.

LiviaMedeiros · 2022-01-11T23:43:22Z

Sure, now it's ready.

Also I should explicitly mention that this is a potentially breaking change, if someone actually uses this method with DataView.
Such usage is unlikely; but it's a part of public API and current documentation allows that.

lpinca · 2022-01-12T20:01:32Z

The Web Crypto API is experimental so I do not think we should label this as "semver-major". Can you please also update the doc to remove the no longer supported types?

LiviaMedeiros · 2022-01-12T22:25:08Z

That's great.
Updated the doc.

Raw ArrayBuffer from previous version wasn't acceptable and didn't work:

crypto.getRandomValues(new ArrayBuffer(8)); // DOMException [TypeMismatchError]

LiviaMedeiros · 2022-01-12T22:53:36Z

Rebased to make linter happy, updated list of jsGlobalTypes to make type parser happy.
If the union type looks too pedantic and ugly, it may be reduced to just {Buffer|TypedArray}.
But technically even Buffer is redundant, since its prototype is Uint8Array; and it would require an explicit warning about Float32Array and Float64Array anyway.

@LiviaMedeiros, thank you so much for this PR!

Did a light review, so pre-approving for now, but hope that we can get a more thorough review on this by other collaborators more involved in these parts — would like to see if further improvements can be made here. :)
