TAC Database Client vs ThreatScoopOnionChat
Side-by-side comparison of two open source alternatives
TAC Database Client
This project aims to provide a publicly, community-maintained, and well-organized database to collect Type Allocation Codes (TACs). While other databases exist, they either don't provide the full data set (e.g. by providing a query interface with rate limiting) or are not maintained in a way that we consider helps the community (submission process cumbersome, data not cleaned/sanitized,...). What is a TAC? A Type Allocation Code (TAC) is made up by the first 8 digits of the so-called International Mobile Station Equipment Identity (IMEI) associated with mobile devices. Earlier versions of the 3GPP TS 03.03 specification defined it as 6 bytes. The TAC is a unique identifier to determine the device manufacturer/model and its marketing name. These records are allocated by certain groups and a full list of all IMEIs is maintained by the GSMA.
ThreatScoopOnionChat
# ThreadScoopOnionChat This version is a fork from " https://github.com/session-foundation/session-android ", enfocado en la privacidad. ## How Did ThreadScoopOnionChat Come About? I have always been a fan of privacy and security in communications, and I am constantly researching potential security breaches in messaging applications. ThreadScoopOnionChat emerged after the analysis of this blog "https://soatok.blog/2025/01/14/dont-use-session-signal-fork/", in which several aspects are described as to why using Session is not recommended, and I wondered how it is possible that a foundation focused on privacy—with the grants and support it receives—has not been able to improve this protocol. I still do not understand the answer, since my resources are much smaller than those of a foundation compared to that of a person who is simply a fan of privacy and security. In this blog, certain problems were described: 1> "https://soatok.blog/2025/01/14/dont-use-session-signal-fork/#insufficient-entropy-ed25519" 2> "https://soatok.blog/2025/01/14/dont-use-session-signal-fork/#in-band-negotiation" 3> "https://soatok.blog/2025/01/14/dont-use-session-signal-fork/#public-keys-aes-gcm" This is a forked version privacy focussed from Session. Go Github to check all features implemented.
