(My German is... well, nonexistent, so I'm going off what Deepl tells me you said)

Hmm... When I started using Hive again two months ago, I created a new master password. Didn't look at it till now (just copied and saved). Looks like the first two chars are VG and it is exactly 100 char long. Wow, that seems long. Did I sent that or did the system give it to me... hmm.. I don't remember.

Anyway, and the private keys all start with 5K, except the owner key which starts with 5J
