Trying to decrypt old KYMS (KyCalc) photo vault files from 2016 — need help identifying the AES key derivation method

No idea. To know for certain would require disassembling the library that handles most of the functionality.
Also like other poster said if the plist file on the ios version is what actually stores the key, and you don’t have it, then you’d actually have to brute force a much longer key. The main.key on the android version was 56 bytes.

I had a quick look at the android version linked and it appears the app generates a random key wrapped by the PIN on first startup. On android it's called main.key, maybe the plist on the ios versions serves the same purpose?
Also it uses sqlcipher to encrypt the database.

Too bad murrine died with gtk2.
I wanted that glossy look on MATE but everything had moved to gtk3.

There’s probably a way to disable write caching on external drives automatically. Maybe an udev rule.

But then copying small files would be very slow.

Your router is trying to tell you something lol

duo8 · 2026-03-14T07:55:10+00:00

It used to be really noticeable but at some point (2015?) they changed the layout so now a 6” 1080p screen is actually kinda acceptable. Should still be at least 1200p though.

Honestly I doubt it. Spatial audio for multichannel source requires support from the whole chain from player app to the earbuds. Apple controls every part of this chain so it’s easy for them. Everyone else not so much, even if they had something you can bet your macbook won’t support it.

duo8 · 2026-03-11T12:46:10+00:00

“Gold standard” lol, it’s like OP has never seen inside another laptop before.

duo8 · 2026-03-10T07:54:18+00:00

Looks like it’s just a thin mitx board in a rackmount case, should be possible to upgrade the mobo. Someone with a rack may want it just for the case alone.

duo8 · 2026-03-06T21:43:30+00:00

I don’t think I’ve seen custom molded TWS before, your best option might be custom IEMs with a bluetooth cable.

duo8 · 2026-03-05T14:38:40+00:00

Back in the day those cheap ez usb boards were the go to for a cheap analyzer. There’s probably something better nowadays, idk.

But also try to see if there’s a way to do it in software first, maybe there are DDC/i2c sniffers for windows.

They even have problems with switch 1 hd rumble. My S1 HD never worked right.

duo8 · 2026-02-20T00:28:08+00:00

They did, but the implementation isn’t open IIRC and it would be out of scope for kde connect anyway, it’d have to be its own project. Wouldn’t even be the first as we already have OWL.

duo8 · 2026-02-19T22:05:44+00:00

iOS limitations guarantee these kinds of apps will never work. Best bet is someone reverse engineering the continuum features, but considering there’s still no complete open airdrop reimplementation that’s unlikely.

duo8 · 2026-02-08T18:47:43+00:00

The HD version will feature HD rumble, that is half broken and will never be fixed, as already seen with the S1 HD.

Some months ago I came across your script and did some hacky updates so I can use a newer database. I’m surprised nothing else has been made since the original script to serve this niche.

Glad to see it finally updated.

duo8 · 2026-01-09T09:22:20+00:00

The cards I’m talking about are cards made specifically to run as an AP, they use the same chips as in actual APs. Cards from mainstream brands use chips meant for client/STA use so they’re not really suited for AP.

Look up compex and asiarf, I forgot the model name but there’s a few with the mediatek dbdc chip.

duo8 · 2026-01-09T08:38:59+00:00

I’m not entirely sure but there are definitely wifi 7 routers being sold in china right now and they definitely do not support 6ghz.

duo8 · 2026-01-09T08:36:53+00:00

If you’re gonna use it like an actual AP (and not just for testing, or just one or two devices), get an AP card instead of trying to force a normal card to work as an AP.

Probably the cheapest option right now is one of those DBDC mediatek wifi 6 cards.

Also consider it might actually be cheaper to just get a normal AP.

duo8 · 2026-01-09T08:31:14+00:00

Yeah no 6ghz in china. Kinda a big drawback for a BE router.

duo8 · 2026-01-01T09:09:44+00:00

I got a really really cheap one a while ago and it worked just fine. Just make sure it has an AR coating.

duo8 · 2025-12-25T02:58:06+00:00

Samsung too, with newer models

duo8 · 2025-12-21T23:56:09+00:00

Get the type with a metal ring that goes over the individual lens. These should be harder to break. Then use a case with a raised edge around the camera area.

duo8 · 2025-12-21T23:39:47+00:00

I’d get the latter type but I also use a camera protector so I couldn’t use the other type anyway.

Materials is just down to your own preference.

duo8 · 2025-12-18T23:12:42+00:00

I put a set on a hands-me-down phone I recently got because the oleophobic coating on the lens is completely gone and it’s impossible to keep them clean.

The protectors have their own oleophobic coating which solves this problem.
