Encrypting seed with AES 256

Mentions

Yes, in theory. The same algorithm would be able to crack HSA-256 in general, and others like AES. A lot of different, more important, things would also be crackable (encrypted bank data, password hashes, anything over HTTPS, etc). 1. The value of bitcoin would be essentially zero, so what would the hacker benefit from? 2. That technology would be considered a risk to national security. Whoever or whatever created it would be hunted with the full force and fury of several world power militaries. 3. With that amount of computing power, there are far more profitable (and legal) possibilities.

Just encrypt it and store it anywhere. You can put it on a billboard if you want. I have a container for this purpose with disabled network. Encrypt it with AES256 or something, then make an armored output, then make a QR code, then make a tattoo of that QR code 😁 Or just print that QR code Or engrave that QR code Numerous possibilities really as long as it is encrypted properly - you are safe.

AES-256 is not quantum safe. You need 6.8k qubits to break it. We are at 1.2k qubits currently. Assuming moore's law applies to quantum computers, it'll take 2-3 years to have a quantum computer powerful enough. Bitcoin hopefully swaps to a quantum safe encryption by then, but doing so is non-trivial. Apple's pq3 is not completely quantum safe, and dilithium is weak against classical computers.

r/CryptoCurrencySee Comment

I mean, you say people are not imagine its magical, yet your comment make it look like that. Let's assume you have a big QC available. Its good enough to break known algorithms vulnerable to Shor, like RSA, ECDSA or Diffie Hellman. It is not good enough to break other stuff, even if it can get an advantage via Grover like SHA or AES. Company A is your target. It's one of those systems you want to fill with trojans, rootkits, backdoors, escape hatches and who the fuck knows. Let's make things easy for you, one of Company A employees have connected to company A VPN from a public wifi that you got access to. You were able to steal the traffic and get that employee credentials. Because Company A is not making use of two factor authentication for the VPN, so you can now connect to Company A VPN as that user, and to make things simpler, you now have shell access to one server in the company as that user. Now what? QC helped you get to this point, but now you have a problem. QC will not give you root access out of the blue, and every action you do from now on has the chance to expose you. Just the act of connecting to the VPN itself can be easily flagged by the security team (two connections from different geographical zones or you connecting via VPN from the outside while the employee is known to be in the office). You could set up an alternative access bypassing the VPN, but that will most likely be flagged by the networking team too. Even if you manage to get a local privilege escalation and become root (that could be quickly flagged, btw), you still need to potentially do multiple jumps to different computers in the company before you can set all your stuff. And this is not a wifi, this is now a wired network. You won't see traffic that wasn't directed to your server. I guess your best bet would be to try to connect to a kerberos AS or go back to the VPN, see if you can snoop more credentials of users. But unless someone connects to those servers from the one you are on right now, you don't really have a way to do it. QC helped you with the initial step, getting those initial credentials, but the rest? No, everything else is up to you. How long until you get find out?

We are working on a hypothetical scenario on which a QC computer with enough qbits to break ECDSA can actually be built. Whether our current inability to produce one is a technical limitation or a physical limitation I don't know. The number of qbits on existing QC has been increasing, and the pace has increased too, but they are still very far from the amount of qbits that will be needed to effectively break ECDSA. Whether that point is reachable or not is still to be determined. It is clear based on the amount of investment there is enough people that believe it can be scaled, but it is also true that just because enough people believe something can be done, it doesn't mean it can. Regarding bank and session cookie, yes, that is the whole point of decrypting the traffic, either get the username/password or pick the session cookie. But that doesn't change anything. I don't know how is it with your bank, but in mine, logging into my bank allows me to do some basic operations (like check my accounts), but when I want to send a transaction, it will not go through without a second validation, be it SMS or 2FA (authenticator). I put the example of SMS because it may be simpler to hijack (and I didn't even mentioned banks blocking transactions that look suspicious, which would be another hurdle), as 2FA is based on a shared secret and is QC resistant. I assume there are banks out there that allows for transfers without the extra security, but I wouldn't be confident using them. After all, stealing credentials or cookies can happen without a QC. Regarding AES, you mention that nothing is resistant if you have the private key. And that is true, whether you have a Quantum Conputer or not. But having a QC does not magically break AES and tell you the private key. It does reduce it's security when performing Grover's attacks, but that means AES-256 would be as secure to a QC as AES-128 is to a regular computer. And we are very still far from breaking AES-128 with classical computers. So that leaves us with the idea of "If you have a QC, is Bitcoin worth attacking?" It certainly represents a lot of money, and by carefully choosing what wallets to attack, a lot of money could be extracted from the system before being detected. Sure, other targets exists, but as we discussed, it is not "point & click", you don't "just hack the bank and get the money".

Sorry, but I don't agree with you here. First, the non-controversial part, ECDSA is vulnerable to a machine that as of today or the near future, cannot be built. But if that machine were to be built, it would be vulnerable. That is different to other cryptographic schemes, were even if this QC computer were built, it wouldn't be vulnerable. Now, into the meat part. QC as an instrument to break cryptography doesn't mean you immediately have access to every bank/military/etc. It will be extremely powerful, but doesn't mean you have a button that says "hack" and it works. Let's imagine I do have that computer, one that can instantly hack non-QC resistant ciphers like RSA, ECDSA or ECDHE. What would it take for an attacker to steal money from the bank? So, what does the hack allow them? Well, if they get access to my traffic while I connect to the bank, they can decipher it. That means they are able to see my user and password. But having my user and password is not enough to get access to my money, there is an SMS that needs to be sent. So they also need to hijack my phone company, or the cell network in my area. Or alternative, instead of just capturing my traffic (not so easy honestly, most wifi are protected by AES, which is QC resistant), but to establish a MITM attack. With that approach, they could create a "fake" website of my bank that would look like legit (thanks to the computer, they will present what my computer will consider a valid TLS certificate), wait for me to do a transfer or another operation that requires the SMS and use that code for them). Establishing a MITM attack would require some extra work, mostly hijacking a DNS so they can redirect my traffic to them, but let's assume they already control my traffic, maybe because they are an ISP or I'm accessing my bank through a public wifi or something like that. Also, they don't know how much money they will be able to steal from me. Do I have $100 on my bank or $100000? And even after all that, there is a possibility that the transfer will be rolled back, and if the bank detects there is a QC attack, they can block access via web to the accounts, force customers to go to the office (yes, horrible, but possible) and eventually, bring the web back online with some QC safe approach. That's not the case for Bitcoin. I don't need to attack your communication to the bank and your SMS or your DNS or something like that. I just need to look for wallets I can hack, and start getting money. Sure, if I get greedy and go for high profile wallets like Satoshi (actually, these may not be possible, you need wallets that have signed a transaction already to hack) or big exchanges I will be noticed and Bitcoin value will tank, but I can get a lot of money from less prominent wallets. You could try to sell the magic QC computer itself, selling to someone that is interested in using it to attack other, more specific targets, like military ones. But I'm not sure that is a great idea, there is a good chance you get "silenced" instead of paid.

My 2 cents: 1) download veracrypt portable from official website, verify installation checksums and signatures 2) disconnect your computer from internet 3) create encrypted container disk, mount it, write you seed there in text file or store you wallet/primary keys/etc there (does not mater) 4) imagine yourself 17+ character password containing symbols, numbers, lowercase uppercase letters. Learn about strength of padded passwords ( [https://www.grc.com/haystack.htm](https://www.grc.com/haystack.htm) ) 5) never write this password anywhere, don't tell anyone. it must exist only in your head. Memorize it, repeating makes master. 6) for several days or weeks, try at at least once a day disconnect your computer from the internet, and mount encrypted container using memorized password 7) when you are sure that you know this password by heart and never forget it, make as many copies of this volume as you want, upload it to 25 cloud service... does not matter - AES is unbreakable if you use strong password. It is industry-strength protection. It would take about 100 trilion years to brute-force long strong password. Now you have your secure encrypted container which contains your seed/wallet/primary keys, and only "physical copy" of password for it exists in your head.

Turn your seed into a AES cipher with a strong password. Stamp the cipher into several metal plates. Keep one for yourself, and leave the others with trusted family members. Now, you can recover your seed with any one of the metal plates as long as you have your password (store this in password manager). Now, your seed is backed up in multiple locations. Even if one of your trusted family members betrays you, they can't do anything with the metal plate, since they won't have the password to decipher your seed.

Thank you for your insight. So, if I use AES-256 encryption, the only vulnerability would be the password I use. Provided I use a strong enough password, I can't see why I couldn't just store this encrypted file in the "cloud" in case the usb is lost for some reason.

Mnemonic seed security has not changed for 10 years. It is hacker proof because it never ever exists in digital form outside of your hardware wallet. You can write it down on paper with a pencil, or stamp it into metal with a hammer. There are some newer options now from SeedQR (you stamp the unencrypted seed into a QR code grid for a stateless signer like Seedsigner), Trezor T's SLIP39, BlockchainCommons' SSKR, and Coldcard can write an AES encrypted .7zip of your mnemonic seed to MicroSD

Actually AES encryption is safe even in with quantum computing. Because current know attack on AES cut key length to half. So 256bit encryption effectively becomes 128bit which is still safe. But basic 128bit AES can become vulnerable because 64bit key length can be cracked today.

Unless you're confident the password is less than 10 characters, you've got practically 0% chance of brute forcing it. The main problem is that the passphrase is converted to AES 256 and then several rounds of hashing/salt are used to make things hard. Therefore you can't just attempt a single combination, it has to be attempted as many as 1000 times to compensate for the hashing/salt.

What I did for a while was store the keys in an encrypted 7-zip archive (AES-256) with a rediculous password, nested that inside another 7-zip archive with a different rediculous password, then I kept a copy of that on a couple flash drives (used BitLocker To Go, so 3 layers in that case) and one in my Google Drive. This doesn't facilitate transacting, but for long-term holding it gives you redundancy in case your house burns down and you are relying on industry-standard encryption instead of some company making hardware trying to handle your keys.

Noooo, don't ever put it online. Use a proper secure airgapped computer running Linux. Use OpenSSL in the Linux terminal to AES encrypt your seed. Write down the cipher on paper and bring it with you. That way, your seed has not been exposed to the internet, and the cipher you wrote down can only be decrypted with your secret password.

Sure on USB, but this isn't the main problem. If you reaaaally want secure communication between PC and MCU, then you need AES encryption. Anything else is tricky. AES key can be exchanged using ECDH protocol. So far so good. Now the problem is that AES encryption must be done inside MCU, not inside the secure chip, because MCU is the one who needs valid data to be decrypted. According to the ECDH protocol (or RSA for instance), AES key is calculated from the exchange of public components, and then computed using private keys on each side. Private key is stored on the I2C-connected crypto chip and never leaves the chip (which is the only correct way). This means that AES crypto key MUST be computed on the secure chip (remember, connected via I2C to the main MCU, which needs this AES key for the future). Now, AES key must use I2C communication between main MCU and secure chip, to perform the task. That being said, if someone, for some reason, has access to sniff I2C lines between MCU and secure chip they can have an access. Company behind the wallet may say "we use personalization, light encryption to transfer AES key". Sure they can, but main MCU is NOT physical attacks resistant, making it prone do hack. Code is open source, so it is just a matter to analyze the code to find address of where in memory is this "personalized algo key stored". For an attacker, this definitely isn't a one day task, but way way more. they have to do many tricks to gain access to the main MCU. Still, if there is an organized group to go towards them, they are less secure than Ledger in that sense. Because in case of Ledger, EVERYTHING is in one chip. All the crypto apps, all the crypto keys.

I have encrypted my seed with AES and it requires a key for decryption. The key is not stored anywhere, it's in my head and easy to remember. I'll never forget it. I have a QR code as an output, that must be deciphered using the key. So I can replicate that QR code in several places to make sure I never lose it, and simply decipher it using the key I memorized, and recover my seed. I don't care if somebody finds the QR code. They can't do shit with it. They don't even know what it is. Engraving your seed in clear is retarded, because then you have to hide it and make sure not to lose it either. It's much better to hide a decryption method in your head, and re-generate it whenever you need it.

Use any software with encryption capabilities. Like WinZip or WinRAR (buy the license, you'd be part of a very small club), or gpg on Linux. There's about half dozen ultra common ciphers AES is the fastest but you can use blowfish or something slow since your clear text is just a few bytes long. Encrypt wallet option in many wallets uses AES to encrypt the file. But it's unusable unless decrypted so must be done on secured environment. Do not invent your own "ROT 7 plus backwards" or whatever. It will be weak even if it seems clever.

Key reuse is a mathematical issue, a potential pattern weakness for AES. Salting also defeats rainbow tables of passphrase-key pairs. In this use case, the salt is recorded in the metadata stored with the cipertext. It's not secret. Similarly, when PBKDF2 is used for passphrase-based authentication, the salt is recorded alongside the hash. It's partially secret, depending on whether the shadow file is leaked BIP39 PBKDF2 does not record the salt. It's not necessary to record it. The 512-bit "seed" is nothing more than the starting entropy for BIP32 HD key chains. So the salt and the payload are equal components of PBKDF2's initial SHA2 payload

Indeed it is. Can use any strong, modern encryption with a very strong, unique, long passphrase. IIRC 7zip supports AES, as does Office. Better yet, use a well vetted password manager or key storage program like KeePass, OnePassword, etc. depending on your threat model. I would only recommend storing encrypted seed phrases for hot wallets (spending money wallets) that are already PC/mobile based. Don't type a cold wallet (hardware wallet) seed into a PC/mobile, even in encrypted form. This is b/c it breaks the security model of generating and storing keys offline and away from general-purpose compting devices.

That's not quite what obscurity means in the context of cryptography. In crypto, we generally say that an algorithm is secure if all details of the algorithm and its workings are public/known information, and the only *secret* is the key/passphrase. For example, modern symmetric encryption like AES. AES is everywhere, people know all of the very standard operations involved. AES is secure provided proper implementation and a good secret key. Contrast this with "security through obscurity" like the above. Just encoding a seed as base64. If an attacker finds out or guesses the implementation details (that the secret is just encoded as base64) then the "security" is completely broken. All the attacker has to do is decode the base64. I can encrypt a piece of information with AES and publish the ciphertext, and challenge people to decrypt it. They can't, without doing attacks to guess the secret key. If I publish base64 encoded information, tell people nothing about the methods of encoding that information, and someone will be able to extract the plaintext almost immediately.

You can crack easy to remember pass-phrases very fast with rainbow-tables. You would have to use a strong encryption (like AES256) but it doesn't matter if you use an easy to guess password. So you create a strong password. Now you have the same problem: you have to store securely a key.

Even discounting human error I still wouldn't bet that no one ever finds a vulnerability or a trick to make even AES-256 decryptable within a human meaningful amount of time. When the service in question is talking about persisting data for, at a minimum, 200 years then I wouldn't want to take that bet. And of course there's always the far more reliable way of cracking something like this, which is get the key from the user(s). Yeah at that point the encryption algorithm doesn't matter, but it's still a risk when talking about any publicly posted data. The more valuable the data the greater the risk, hence why anyone pushing for stuff like government documents or medical information on the blockchain is a moron!

No, the truncation of 256 bits will not give you GUARANTEE of a unique number translated from a sequence of numbers. Translation via matrix, like in AES, does that. If you keep adding 1 to an input and hash it once with AES, the resulting 128 bits are guaranteed to be unique, with no repetitions, no matter what key you choose. But if you truncate AES output to 66 bits, it is possible number 747374 AESed first 66 bits will be exactly same as +1, so 747375 AESed could in theory result in the same first 66 bits followed by different bits. Next, hashing algos in general are lossy in nature , o by design, you also could have collisions of your sequence inputs resulting in the same 66 bits. The best solution would be getting AES-like 64 bit algo (3DES for example), running it on 0..64bit sequences and the remaining 2 bits reserve for your threading, so choose assign each combo of them to each cracking thread, or if its one, run through them for each sequence number. For a single thread, assuming you're using 3DES it would go like: Input seed value (default 0) -> x For (unsigned int128 i=x, i<=0xffffffffffffffff, i++) { X0=3DESEncrypt(i); X1=3DESEncrypt(i^1<<64); X2=3DESEncrypt(i^2<<64); X3=3DESEncrypt(i^3<<64); ValidateBtckey(X0); ... ValidateBtckey(X3); ... } This way, you run through all sequences of 0..64bit in unique random way, no repetitions possible.
