 Explanation:
   - Convert JWK to PEM
   - Load PEM with nodeForge
-  - Convert msg buffer to nodeForge buffer: it's already uint8array, so do nothing
-  - Convert resulting nodeForge buffer to buffer: it returns a binary string, turn that into a uint8array
+  - Convert msg buffer to nodeForge buffer: ByteBuffer is a "binary-string backed buffer", so let's make our buffer a binary string
