hashBrowser

JS TODO

Creates a hash for a value using the SHA-256 algorithm. Returns a promise.

Use the SubtleCrypto API to create a hash for the given value.

const hashBrowser = (val) =>
crypto.subtle
.digest("SHA-256", new TextEncoder("utf-8").encode(val))
.then((h) => {
let hexes = [],
view = new DataView(h);
for (let i = 0; i < view.byteLength; i += 4)
hexes.push(("00000000" + view.getUint32(i).toString(16)).slice(-8));
return hexes.join("");
});
hashBrowser(
JSON.stringify({ a: "a", b: [1, 2, 3, 4], foo: { c: "bar" } })
).then(console.log); // '04aa106279f5977f59f9067fa9712afc4aedc6f5862a8defc34552d8c7206393'
