Какие ещё нужны док-ва, что т.н "госмессенджер макс", это очередное поделие ВК (точнее переделанный ТамТам)

Developed a library for working with ICAO Visible Digital Stamps (VDS). I like this standard; it is much simpler and more standardized than whole eMRTD.

ISO/IEC 39794 is good replacement for ISO/IEC 19794, but i have never seen so many "pyramid" ASN.1 structures. tsemrtd will implement this standard, but only for mandatory fields and only for DG2 now

"Many thanks" to Roskomnadzor, cuz now I can't open sites that using @cloudflare.social without using VPN.

btw GPL (and AGPL, LGPL) sucks, use MIT
I got permanently banned from r/opensource on reddit for saying GPL license is bullshit. wow that's fucking pathetic lol

Why do I have to specify an explicit type for constants?
I understand that this should work with variables, but constants just got me...

Context: Project has no dependencies at all, but JSR changed format of Bun lock file (.lockb -> .lock), and also throwed error 🫠

How do know which Swarm is serving specific Session ID?
- Split Session ID into 4 parts of 8 bytes and XOR each other.
- Next, you need to find closest Swarm ID value in blockchain
Example: d31609a18228b69e -> d300000000000000 (closest value in blockchain)
- Split Session ID into 4 parts of 8 bytes and XOR each other.

Messenger Session in new Blinded ID algorithm makes same mistake as in old algorithm.
Again failed if-condition is used to check the sign bit (pk[31 & 0x80) to generate hash of the server's public key, as result we again have 2 variants of possible public key when converting key pair

It's pretty funny that Session messenger uses 16 bytes, obtained from the seed phrase and not modified in any way, as the Ed25519 private key for your profile 🫠
