AES256-CBC only requires that IVs be unpredictable, so I don't see the need to generate IVs via PBKDF2, nor do I need salt; this approach would waste a lot of time.
Using hashed random data as IV can have the same effect, both crypto.randomInt and crypto.randomUUID can generate random data. This approach will be less time consuming.
