Without accepting this pull request your project will work just like it did before. There might be a bunch of new features, fixes and perf improvements that the maintainers worked on for you though.

I recommend you look into these changes and try to get onto the latest version of tweetnacl.
Given that you have a decent test suite, a passing build is a strong indicator that you can take advantage of these changes by merging the proposed change into your project. Otherwise this branch is a great starting point for you to work on the update.

Release Notes

v1.0.0-rc.1 (Release candidate)

• IMPORTANT! In previous versions, nacl.secretbox.open, nacl.box.open,
  and nacl.box.after returned false when opening failed (for example, when
  using incorrect key, nonce, or when input was maliciously or accidentally
  modified after encryption). This version instead returns null.

  The usual way to check for this condition:

  if (!result) { ... }

  is correct and will continue to work.

  However, direct comparison with false:

  if (result == false) { ... }

  it will no longer work and will not detect failure. Please check
  your code for this condition.

  (nacl.sign.open always returned null, so it is not affected.)

• Arguments type check now uses instanceof Uint8Array instead of Object.prototype.toString.

• Removed deprecation checks for nacl.util (moved to a separate package in v0.14.0).
• Removed deprecation checks for the old signature API (changed in v0.10.0).
• Improved benchmarking.
