Er schreibt immer wieder besonders viel an Wochenenden und Feiertagen, ggf. einsam.
Und schadet damit selbstverständlich ebenso wie sein "Boss" Ben-Gvir massiv dem Ansehen der Republik Israel.
Immerhin gab und gibt es mutige Stimmen wie eine mutige Generalkonsulin, die ihm öffentlich widersprachen.

🧵 Thread: Building information-theoretic security for personal cold storage
After almost losing access to critical crypto wallets during a team transition, I've been thinking about the cold storage problem differently.
Most people store seeds/keys in single locations: hardware wallets, encrypted files, safety deposit boxes. But what happens when that ONE thing fails, gets stolen, or you forget where you put it?
1/8
🔐 The solution we ended up building uses Shamir's Secret Sharing - the same math that Trezor uses internally, but applied to any secret you need to store long-term.Split your seed phrase into 5 pieces, need any 3 to recover. The beautiful part: 2 pieces reveal ZERO information. Information-theoretic security, not just "computationally hard."
2/8
💡 Real-world threat models this addresses:
🔥 House fire (shares elsewhere survive)
🚪 Inheritance planning (family can pool shares)
🏠 Forgotten hiding spots (only need threshold)
⚔️ Physical coercion (attacker needs multiple locations)
💾 Hardware failure (recover to any new device)3/8
🛡️ The crypto nerd in me loves that this is provably secure:- AES-256-GCM for file encryption
- Shamir's algorithm over GF(256)
- Each share is self-contained with recovery tools
- Air-gapped operation (Docker --network=none)
- No proprietary crypto, everything auditable4/8
🎯 Use cases beyond crypto:- Password manager master vault exports
- GPG/SSH keys you can't afford to lose
- Encrypted family photos/documents
- Any "nuclear option" secret that needs decades of survivalThe key insight: some secrets are too important for single points of failure.
5/8
🔓 Why we open-sourced it:
When your financial security depends on a tool, you can't trust it to any company's business model. Cryptographic tools for long-term storage need to be:- Transparent (audit the math)
- Immortal (survive any vendor)
- Community-maintained6/8
💻 Implementation details for the security-minded:- Runs completely offline
- Cross-platform (Linux/macOS/Windows)
- Each share includes full recovery application
- FIPS 140-2 compatible algorithms

Question for #infosec community:I'm wondering How do you handle long-term storage of critical secrets? Especially curious about approaches that survive both digital and physical threats over decades.
What threat models am I missing for personal cold storage scenarios? -

Rockets launched from Gaza fell in Sderot
I thought Israel had evacuated everyone from Sdrot as one of the first cities before the mobilization of reservists?!These desperate launch of rockets that only cause fear and anger is not going to help Palestinians in any way.
But I guess, it is their desperate show of defiance against the military might of Israel, to show that they are still fighting.
If the peace deal between Arafat and Shamir was not just a sham sell out by Arafat to gain status in delusion of having a Palestinian state, and included real issues such as status of #Jerusalem, disbanding of illegal settlements and the compensation or plan for millions of refugees to have the right to return, there could be a real #peace between the two nations.
Unfortunately, #Shamir was killed and Ariel #Sharon the butcher of #Sabra and #Chatila became PM of Israel and killed #Arafat together with any hope of a real Palestinian state. Ever since then, situation has gone from bad to worse and more than half the population of occupied territories who were born after that "peace deal" have only seen betrayal after betrayal, followed by uprising, brutal crack down and expansion of illegal Jewish #settlements.
The corrupt and useless #PA who turned into extended hands of apartheid regime lost it's power to the radical Hamas that gave Israel the excuse to put a deadly blockade against Gaza and turning into the world largest prison.
From then, we have only seen the spiral of violence on both sides, with the rise of serial liar and corrupt politician #Netanyahu who now have legitimized #Kahanist terrorist group in Israel while the "world" not only given up on a just and lasting peace between the 2 groups, but an unconditioned support of the most extreme form of #fascism in Israel while condemning the same escalation among Palestinians.
10s of thousands of people have died (the vast majority of them Palestinians), many more maimed by #IDF shooting on knee-caps and eyes of protesters for decades (an escalation of #Sharon's breaking the bones of palestinian kids to prevent them from participating in the first #Intifada).
Today we see the bloodiest escalation of this conflict, a level of violence that has gone beyond any laws of war and once again, the "world community" seems to be only condemning one side while cowardly "aaking" Israel to be merciful.
The mullahs in #Iran joyfully watching the conflict turn into a regional war in their wet dream of liberating Palestine or turn the world on fire (like their American evangelical christians) to enter the dooms day and return of #Mahdi (12rh imam of Shia) or #Jesus for the christian crazies.
All with 0 care about the suffering and death they are causing.

Quelqu'un sait s'il existe un programme pour le partage de secret facile à utiliser ?
Ma debian me propose "ssss" ?
J'ai trouvé un depôt gihtub aussi ( https://github.com/codahale/shamir ), quelqu'un a testé ?
