As you said it's 5 characters it takes months to find the password using this tool because they don't support GPU yet unless you know some parts of your password.
btcrecover benchmarks give 10,400 passphrases per second for a NVIDIA GTX 1660 Ti - https://btcrecover.readthedocs.io/en/latest/GPU_Acceleration/. Obviously your values will vary depending on your hardware. A very quick test shows I can get a little under this out of the box, so could probably get quite a bit over this with a little optimization.Still, assuming 5 random characters from the set of lower case, upper case, and numbers, 10k attempts per second would only take a little over a day to exhaust the search space. Add in symbols and use the full 95 character ASCII set then you are still only looking at 9 days to perform a complete search, so 4.5 days on average to crack the passphrase.
