P.S. I'm tired of transferring ASN.1 schema to TS like 10 times and catching errors because of fucking CHOICE

Especially funny situation with Ukrainian algorithms (DSTU)
Kupyna (DSTU 7564:2014) - modified Grøstl;
Kalyna (DSTU 7624:2014) - modified AES;
Strumok (DSTU 8845:2019) - modified SNOW 2.0;
Skelya (DSTU 8961:2019) - modified NTRU;
Vershyna (DSTU 9212:2023) - modified CRYSTALS-Dilithium.

Remarkably, Signal had same problem when developing the XEdDSA and VXEdDSA algorithms, but they solved it by forcibly zeroing the sign bit. (check 2.3 section of specification)
P.S I especially like that "libsession-util" repository intentionally disables issues

Specifications >> The XEdDSA and VXEdDSA Signature Schemes
This document describes how to create and verify EdDSA-compatible signatures using public key and private key formats initially defined for the X25519 and X448 elliptic curve Diffie-Hellman functions.

Also keep in mind that the current Blinded ID algorithm is reversible, i.e. it is possible to get the user ID knowing only the public key of SOGS.
A practical implementation of this algorithm is - github.com/theinfinityw...
