in general, it makes things more readable and maintainable if avoid magic numbers and you instead make this a descriptive constant. E.g., (modulo style, and is this bits or bytes, who knows :-) ) `32_BYTES = 32`), and then `hawkCredentials(sessionToken, "sessionToken",  2 * 32_BYTES)`. This `3 * 32` pattern is all over, though, so whatever.
