How safe is to storage private keys in the cloud?

[400actforsale]

It is unsafe. That's why I had stopped using my blockchain.info account and migrated to mobile wallets where only I have control of my keys. I am also generating some vanity address on my PC (online but browsing only trusted sites like bitcointalk) and store the keys only in my PC's hard disk.

P.S. I have lost a litecoin on a scam wallet site. You have been warned.

[traderethereum]

i am not prefer to save my bitcoin in the cloud, because not all the time, the cloud can be safe and we know it. i think i am feel better to safe my bitcoin into my pc or my android phone so i can manage directly my bitcoin in my wallet.

Can someone know where a private key belongs once a person have found it?

Let's say a private key copy is stored in the cloud and is found for a bad person; is it possible for that person to know where to use that private key?

Noooo. Dont ever, EVER store any private key in the cloud. If you really have to use Pcloud not Dropbox. Dropbox could be working with the NSA in snooping on its users' files.

first of all there is always options for multiple encryptions that even NSA can not break, you should look into them before doing it. you don't just put it up there un-encrypted! anybody can steal that.

second of all so what! even if NSA checks your cloud which there is no reason for it, and then another if, if they break the encryption, are you doing something illegal? are the bitcoins gained from an illegal channel or did you evade paying taxes? if not you shouldn't be worried.

This is not a good option for your funds. There other solutions where only you and someone you can trust have access on it. If these private keys correspond to your savings you can encrypt your private keys and store it in a safe in your home or to a bank locker. If the keys correspond to small amount, how small it depends from you, many members of the above have proposed some very good solutions.

Your bitcoin would get hacked faster than you can see Silently seduce my BTC. In this day and age we should all be using secure hardware wallets for any tangible amounts.

Its a bad habit to do even if you encrypt your files and store it in the cloud. I dont like the idea of a hacker getting them even if I know he cant decrrypt them. Its better to store them offline.

[Taki]

I don't trust such things as clouds. I think as it's possible to steal private information by using public Wi-Fi as it's possible to steal private information using cloud. In the area of new high technologies people have to be careful.

Multiple encryptions would really do to make your files safe even you put it on cloud storage but we all know that not all people is aware to do such action and just carelessly put up any important informations without encrypting thats why its risky and as you said NASA will just check your account or cloud if you do something illegal though.

obviously nobody likes that to happen ever, but if you learn what encryption is and how to do it right there is nothing to worry about even if a super hacker gets your encrypted wallet or private keys online.
it is going to look like this you can try and break this AES encryption all you like but you can never do it in a million years:

you can always take extra security measures like double encrypting the file, and do a password protection kind of thing on top of that, and including it among other irrelevant files which has no indication of bitcoin in them.

Decrypting an encrypted file will really be hard even how good hacker or expert you are.You are right it would really took million years before you could able to decrypt it specially if you make double encryption.No one would could able to touch your keys no matter what.

A private key is the most important part of the wallet because it signifies that you are the owner of a particular

wallet. Now What if someone has your pprivate key, The answer is simple that person can easily access your wallet

by importing it and empty it in one go. Making an online wallet is considered very risky but keeping your keys in a

cloud is one hundred times worse. It is the best for your wallet and every important parts of it to be offline as

much as possible.

[USBitcoinServices.Com]

How about that someone decides to split their pvt key and store half of it in one cloud and the other half in another cloud?

[thend1949]

Yes that will be easy for them when they get your private key,they can easily import and acces your wallet through their device without needing any verification which is bad in the side of private wallet keys.And they can freely spend your bitcoins everywhere

[normanbc]

How about that someone decides to split their pvt key and store half of it in one cloud and the other half in another cloud?

Or even in  three parts.

Sounds like a good idea, but actually it could complicate things for  key's owner .

[the rise]

I am not fully believe to store private keys in cloud storage, all our secrets will open if the emails we've been penetrated by hackers,
I consider the cloud is not a safe way because it still has a gap to be consumed together.

[USBitcoinServices.Com]

Speaking of privacy what email service would you use: Gmail (non encrypted) or protonmail (encrypted)

[dwieyani]

The safest thing it apart offline and credible what?

[Nudlz]

No, just no. Whenever you hear "online" you should know it's not safe to store critical data.

If the owner of the cloud storage wants to f*** you up, they can do that without any problem. What's even worse? They can use your BTC addresses without you even finding out about it.

I'd rather find a safer, offline way I can store my private keys and not let these guys possibly use them without my knowledge and agreement.

Don't do it if you can.

If you definitely have to do it then make sure that you are using a trusted service such as google docs or dropbox that also encrypts your document in the cloud. Don't use any of the small services.

Don't store any more than 0.1 BTC in the wallet either.

Just use an online wallet like blockchain.info. You are probably safer that way than to store your private keys in a cloud storage service.
