I'm working with ReactJS + ArdorJS but the library has some small bugs:

**ardorjs/lib/account add:**  
`import { Buffer } from "buffer";`

**ardorjs/lib/helpers.js add:**  
`import { Buffer } from "buffer";`

**ardorjs/util/curve25519\_.js**  
`export default { curve25519_ };` to `export default curve25519_;`

I hope it can be useful to someone. 😁

mrv777 already merged the **curve25519\_** one. Could you create a pull request for the 2 other fixes so that we can discuss them with mrv777?

**It's ready!**

I also added a fix for decryption, it was not working properly.

> Instead of creating a new byte array with the length of wordArray.sigBytes, you …can create an array with length len \* 4 and then cut the unneeded bytes at the end of the loop. This will avoid creating a larger array than necessary and thus reduce memory usage.

> \*\*It now returns the exact amount it needs and decryption works perfectly.\*\*
> 
> On the other hand, \`\<Buffer\>\` was added to increase compatibility with other frameworks (in my case, ReactJS).
