Try to run as may test as possible to make sure SDK 2.21 for ESP8266 can be released.

function buildKey() {
      var randomString = btoa(Math.random().toString(36).substr(2, 8)+
                          Math.random().toString(36).substr(2, 8));
      var toHash = randomString + '258EAFA5-E914-47DA-95CA-C5AB0DC85B11';
      return {
          source: randomString,
          hashed: btoa(require('crypto').SHA1(toHash))
      }
}

console.log(buildKey());
{
    "source": "MXFwZDFiamFmM2Jyd2xsaA==",
    "hashed": ""
 }

Shouldn't hashed has a non empty string?

Works for strings but not for arrays, created issue #1509
```
>btoa("Hallo");
="SGFsbG8="
>btoa([0,1,2,3,4,5,6,7,8,9]);
=""
```

Don't worry about formatting, just type in the text and we'll take care of making sense of it. We will auto-convert links, and if you put asterisks around words we will make them bold.

Tips:

Create headers by underlining text with ==== or ----

To *italicise* text put one asterisk each side of the word

To **bold** text put two asterisks each side of the word

Embed images by entering:

That's the hard one: exclamation, square brackets and then the URL to the image in brackets.

* Create lists by starting lines with asterisks

1. Create numbered lists by starting lines with a number and a dot

For syntax highlighting, surround the code block with three backticks:

```

Just like Github, a blank line must precede a code block.
