NEAR Protocol - matching base64 strings in JS and Rust

near-base64.js

// JS (node - for browser you need to use btoa(String.fromCharCode(...new Uint8Array(...)))

const hash = sha256.create();
const hashesBase64 = [
	'some string'
].map((src) => {
	return Buffer.from(hash.update(src).array()).toString('base64')
})	
 

near-base64.rs

// RUST

use near_sdk::{log, base64::{encode}};
let s = "some string".to_string()
let token_id = encode(env::sha256(format!("{}", s).as_bytes()));


// Notes for hex (hacky but matches JS sha256('some string'))

let s = "some string".to_string()
let token_id = format!("{:02x?}", env::sha256(
            env::sha256(format!("{}", s).as_bytes()
        )).replace(", ", "").replace("0x", "").replace("[", "").replace("]", "");
