- Make POW checked before captcha in POST handler, since they both must be submittedin captcha mode, we don't want to send POST to /siteverify if they didnt even solve the POW
Other:
- Change (improve) split util to leave empty table entries for repeated delimiters
- Minor frontend script bugfix so error messages display properly in captcha mode
- Wrap submit button of noscript pow form to next line
Make failed request for captcha/bot form show a little error text.
Make CHALLENGE_INCLUDES_IP "1" = on, anything else = off instead of needing to be unset.
- memory and time params customisable as well as "difficulty", default 1 iteration, 6000KB, 3 difficulty.
- updated the noscript bash method to work with argon2
- works in webworkers or main thread, capped at 8 threads (doesn't seem to crash firefox anymore -- we could go higher)
Still TODO actually converting it to argon, but should be straightforward from this point.
Another advantage of making POW check use POST is a better noscript experience. We now provide a box and "submit" button, so they don't have to mess with setting a cookie.
- Move to new scheme with some hashing, sigs, and a random user key. close#13
- Change to sha256 rather than sha1 (temporary, but i guess its slightly more secure which is nice for now) ref #10
- Change POW output checked value
- Add lib for randombytes, udpate lua sha lib
- Remove outdated difficulty checks in frontend (was hardcoded 0 anyway) and since algo change is coming soon, there is no need to keep it
- Reduce the default concurrency of the frontend script to 2 threads because any higher seems to crash firefox (and its quick enough even with 2 threads anyway)
- Remove the footerlogo from challenge and maintenance page, and update the link
Even if a lot of distros just symlink sh > bash the script needs to do some substitutions not supported in sh, so it's more correct. Who doesnt have bash these days anyway?
old code was just dumb, dunno what i was thinking.
now domain+path takes priority and can be lower or hight level, not just higher level than domain only.
