It seems like the benefits are having the device lock/wipe itself after a set amount of attempts in case of a brute force attack and not having to run software to decrypt the drive on the device you plug it into.

I included a picture of the IronKey Keypad 200 but that's just because it's the first result that came up when I was looking for an example. There seem to be a few other manufacturers and models out there and they probably have different features.

I am curious what do you think of them? Do you think they are useful? Do you find it more a novelty?


It was an ExplainingComputers video titled Very Useful Small Computing Things that made me think of them.

It seems like these drives can use up to 15 digit pins and lock out after a set number of attempts. I don't know if that would be a huge issue

It still drastically narrows down the search space and makes social engineering a LOT easier.

Because you tend to have one of two sources for any password that people need to remember.

  1. Randomly generated with no rhyme or reason. And written down on a sticky note as a result
  2. Something with meaning to the user

And it is the latter where this becomes an issue. Because let's say they are a 50 year old and 1, 4, 6, 7, and 9 are heavily worn. Well, they were born in the 70s so let's verify exactly when. Hmm, May. No 5 means it probably isn't their birthday. Wait... their partner was born on April 7th, 1976. No luck. Oh, but what if they were clever and it is actually 197647 instead of 471976? Boom, in.

Related XKCD

It's a shame more people don't think of obscure numbers they've been forced to remember in the past or see constantly and use those.

  • A number from a song

  • Your middle school locker combination

  • The number of a local pizza place

  • Your library card number

  • The barcode number on something you carry around all the time

If you combined any two of those I imagine it would make for a pretty secure password.

Ironkey has been more careful than some other vendors but the concept still seems dubious to me, if you are trying to stop serious attackers. You want the decryption key to be completely separated from the storage.

Ironkey has been more careful than some other vendors

In what aspects? I don't know much about these specific devices

[–] solrize 11 points 4 months ago* (last edited 4 months ago) (3 children)

Cryptography and tamper resistance implementation. E.g. search "ironkey fips certification". Ironkey is a Kingston brand now though, and Kingston has traditionally been crap, so be careful. Anyway if it's for run of the mill personal files where you just want some extra protection, the device is probably ok if you don't mind the semi-ridiculous cost. This is interesting though: https://www.wired.com/story/unciphered-ironkey-password-cracking-bitcoin/

Also a teardown report: https://hardwear.io/netherlands-2021/presentation/teardown-and-feasibility-study-of-IronKey.pdf

There are more serious technical approaches to data protection, but fairly quickly the weak spot becomes the humans in the loop, which are harder to handle with pure technology.

Do encryption in software. History taught us hard lessons about this.

[–] [email protected] 13 points 4 months ago* (last edited 4 months ago) (1 children)

Can you think of some notable examples of hardware based encryption failing?

Besides the actual device dying I mean

I had one of the SanDisk flash drives that had some launcher thing on it and I had a password for some reason on it.

In high school, a classmate tried to guess it, 3 times and I lost everything on it forever, since it stupidly locked forever after 3 tries.

I had software projects from back then that I can never get back.. including a web browser. I could have had the next Firefox..

If you're out there, Liz: I'll never forgive that.

[–] [email protected] 9 points 4 months ago

Liz taught you to make backups of data you value

[–] [email protected] 6 points 4 months ago (1 children)

Was it going to be open source ?

[–] [email protected] 14 points 4 months ago

I didn't know what that was yet.. but probably.

[–] [email protected] 28 points 4 months ago* (last edited 4 months ago) (1 children)

Hardware signing devices have lots of utility because they keep the key from ever being on the machine (which is more likely to be compomised). Think ledger or trezor for your Bitcoin. Hardware encryption devices are just really expensive and black-box ways to avoid Veracrypt.

If your encryption algorithm is secure, you have no use for automatic lock-out. If it's not, automatic lockout won't do much against an attacker with physical access to the device. Unless they are dumb enough to trigger the lockout AND the internal memory wipes itself sufficiently well AND/OR the attacker doesn't have the resources to reverse engineer the device.

Like most things, it's important to remember what threats you're trying to protect yourself against.

Are you trying to protect yourself against dropping a USB in a parking lot and someone picking it up? Or are you trying to protect yourself from a nation state?

[–] [email protected] 9 points 4 months ago

Just my opinion but I don't really like the common belief of separating nation and non nation state actors. We're getting to the point where nation states are making up a large portion of the really damaging attacks, and it's frequently ones own government or a government they're in conflict with which means there are very kinetic consequences for failure even if you're a nobody. It's not just someone stealing some money anymore.

They occupy a strange niche full of contradictions.

Entering the code on the device itself should increase security as opposed to entering it on a compromised computer.

But plugging it into a compromised computer means the data is compromised anyway.

Their security is way harder to audit than a software solution like PGP. The actual "encryption" varies from actual decent setups to "entering the code connects the data pins with no actual encryption on the storage chip"

Not having to instal/use software to use them means they are suitable for non-technical users which in turn means more support calls for "I forgot the pin, it wiped itself, can you restore my data"

They are kind of useful to check the "data is transported on encrypted media" box for compliance reasons without having to manage something bigger.

Yeah i dont see how this would be better then a run of the mill thumb drive (that doesnt scream im worth stealing) and just creating a cryptomator vault on it.

[–] fidodo 5 points 4 months ago (5 children)

Is that solution portable for any device and os you might plug it into?

These are handy if you have to move sensitive information but I've experienced more than one event at work where irreplaceable files were lost due to user error on these type of drives.

I couldn't tell you about the lifespan of these devices either, something tells me the keys won't last more than a few years if it's being used regularly.

I wouldn't trust any part of its hardware and software to store anything worth encrypting on it

[–] [email protected] 16 points 4 months ago (1 children)

Looks find to me, depending on your use case, everything would have a use case

Many people mention airport red flags and checks, for me I never had any issues with the airport stuff, except one time in China when I had a full case of wires, really 10kg of wires, and they just asked me me to open and show, np

[–] [email protected] 21 points 4 months ago (3 children)

Why did you have a 10kg bag of wires?

[–] BeMoreCareful 32 points 4 months ago (2 children)

What, do you work at a Chinese airport or something?

I like wires! Who doesn't like wires??

I donct have much stuff, but i have a lot of electronics, and at that moment i was very into sdr, so, wires, antennas, adapters, antennas, wires, and also additional hdmis, vgas, ethernet cables, usb, chargers, etc, etc, etc

Fair, I do like wires

What do you buy when you're in China. Dude wanted cheap wires. Let him have his cheap wires.

The ones that went through FIPS 140-2 Type 3 or above validation are legit. We used Apricorn for CUI data…examples: https://www.archives.gov/cui/registry/category-list

I don't trust hardware implementations of encryption in the same way I don't trust hardware raid arrays.

[–] [email protected] 11 points 4 months ago (5 children)

Useful for what? Hiding stuff from family-member or coworkers? Yeah sure. Why not.

Hiding stuff from professionals that really want your data? Probably not very helpful.

Also what about backup? One controller-malfunction and your stuff goes poof. I just assume the data is somehow important or else you wouldn't care about such a device 😊

Too expensive. Use software encryption instead

[–] [email protected] 8 points 4 months ago

First time I've seen something like that, but my initial thought was: wow, that's a lot of parts that can break and things that can go wrong (compared to only encrypting the data itself before storage).

[–] [email protected] 8 points 4 months ago* (last edited 4 months ago)

Same problems as any firmware based encryption (encrypting SSDs, etc.). Firmware is quickly outdated and the triangle price - speed - security usually neglects the security part.

[–] [email protected] 8 points 4 months ago

like everyone else has said hardware level encryption doesn’t seem like the most sound option.

Personally i’ve just encrypted sensitive files with picocrypt, only just started looking into better encryption techniques though so there’s probably better alternatives.

[–] Jiggle_Physics 7 points 4 months ago

As long as the security software it uses is solid I think it's a decent idea.

[–] [email protected] 7 points 4 months ago

Good until you spill a Cuppasoup on it's chinesium keyboard.

[–] [email protected] 6 points 4 months ago* (last edited 4 months ago) (2 children)

What is your use case for this?

  • Confidential files in a public setting? Don't fucking bring confidential files to a public setting. But if you must, a big bulky laptop with (good) FDE is a lot more sequre than a flash drive someone can pickpocket.
  • Border crossing? Guess what? You paint a MASSIVE red flag on your back and get to learn that you don't actually have all that many rights in the time between stepping on foreign soil and being admitted by customs. Congrats, you gave them the wrong code three times and it got wiped. They are going to break your face and put you in a black site.
  • Hiding sensitive/highly illegal content in the event of a police investigation: Yeah... if you are at the point where there is a warrant (or black van) out for your arrest than it really doesn't matter if they can see whatever you were looking at last night.

At my old job we required these for "thumb drives" and all they ever did was make reformatting machines pure hell.

Stopping low effort attempts to get data it seems good, as an addition too software encryption it seems great. Of course hardware can range from child toys, gimmicks, to serious hardened hardware, so results WILL vary.
