Title: finally memorized my private key :D Post by: slaveforanunnak1 on August 03, 2014, 12:06:05 AM I have several wallets, some cold, some hot, but one has the most amount of BTCs in it. Of course it's one of my cold ones and i decided a few weeks ago to memorize the private key. Today, i like to say i managed to do it.
Anyone else done this? It's not that hard, if you memorize them in chunks of 4 for a few weeks. Title: Re: finally memorized my private key :D Post by: bigasic on August 03, 2014, 12:08:19 AM I was going to do that but since the key is so long, I can see me forgetting on or 2 characters, especially if I dont repeat it daily. I would never memorizing it as the only copy. Now memorizing it and having a paper copy, now thats doable, even for me, lol..
Title: Re: finally memorized my private key :D Post by: Mitchell on August 03, 2014, 12:10:45 AM Well, congrats on remembering it, I think. I can honestly say that I won't be able to remember something like that. I can barely remember the birthday of my own mom, so how would I remember something like that? ;D

Title: Re: finally memorized my private key :D Post by: herzmeister on August 03, 2014, 12:26:49 AM i guess it's possible by forming a story out of the characters of one's private key, by expanding them into words... that's how these brain-masters in TV shows do it
leave a character out or two and the story wouldn't make sense anymore.

I can honestly say that I won't be able to remember something like that. I can barely remember the birthday of my own mom, so how would I remember something like that? ;D Try it bud, this is what i did. When I created my wallet from bitaddress I kept hitting "generate new wallet" until I saw a funny word at the start. we all know they start with a 5. Here is an example address; 5NiNJA Lf9z gWQn ogid DA76 MzPL 6TsZ ZY36 hWXM ssSz NydY XYB9 KF 1234 5678 9012 3456 7890 1234 5678 9012 1234 5678 9012 34 so memorizing NiNJA is easy. The rest I did like this: Day1. After the shower, I wrote down 4 charachters on the palm of my hand. ( luckily i have a lot of meetings at work, so i get to look at my hand a lot. :D) Lf9z Day2. then i wrote the next four on my hand. gWQn Day3. All eight. Lf9z gWQn Day4. All eight.

The other 10 % I just had to work on a bit to get it. (association with things) I will def keep a paper copy somewhere. I've had several head injuries.

It's not that hard, if you memorize them in chunks of 4 for a few weeks. You should have converted it into a mnemonic of English words. Or started with diceware and sha256ed that to get a key pair. http://world.std.com/~reinhold/diceware.html Title: Re: finally memorized my private key :D Post by: keithers on August 03, 2014, 01:23:21 AM That is pretty impressive, congrats. Obviously you are keeping several physical copies. Would give you an anxiety attack trying to type it in if you forgot 1 or 2 keys and couldn't figure out which one you were messed up on...

Title: Re: finally memorized my private key :D Post by: Yakamoto on August 03, 2014, 02:00:35 AM Memorizing a private key?
Yeah, I'm out. No way I would be able to memorize an entire private key. It's pretty hard, even with all the patterns in it... Congrats, though. That's probably the best security you can possibly get. Title: Re: finally memorized my private key :D Post by: tmbp on August 03, 2014, 02:18:30 AM Why not memorize hashing functions plus entropy instead? For example SHA256("I like to post on bitcointalk and remember easy entropy.") this way if you get hit on the head your private key will not be lost.
Title: Re: finally memorized my private key :D Post by: jonald_fyookball on August 03, 2014, 02:23:48 AM Why not memorize hashing functions plus entropy instead? For example SHA256("I like to post on bitcointalk and remember easy entropy.") this way if you get hit on the head your private key will not be lost. as long as your phrase has enough entropy. best is something like electrum. human chosen phrases are dangerous unless you really know what you're doing. Title: Re: finally memorized my private key :D Post by: Watoshi-Dimobuto on August 03, 2014, 02:24:23 AM I think memorizing private key is not that hard.

A good option is to store your private key in the vault but encrypted with bip038 Title: Re: finally memorized my private key :D Post by: Omikifuse on August 04, 2014, 12:25:51 AM finally memorized my private key "We have ways of making you talk." :D The same ways can be used to make OP tell where he puts the private keys, so we are still tied. And this way OP can deny the very fact that he has something to do with the bitcoin address or that he owns or owned the private key, what can be usefull in certain situations(that would be usefull for the silkroad guys).

It sounds easy to get wrong or forget, but it really isn't. I recite it every morning for over one month now. My other idea was to tattoo the private key underneath my armpit which would get hidden by the hair when it grows back, or on my ass crack or somewhere random like that. Obviously you'd need to trust the tattoo artist. Title: Re: finally memorized my private key :D Post by: jubalix on August 04, 2014, 06:54:01 AM and if you want to use another address....

Agreed, that's the problem with memorising a private key over a seed... With my brain wallet I can simply add another digit to my pass-phrase and it becomes a whole new brain wallet. Title: Re: finally memorized my private key :D Post by: Mobius on August 05, 2014, 05:56:59 AM I think this is a very dangerous way to store your bitcoin and will likely give you a false sense of security. You may be able to memorize something today and remember it accurately next week or even next month, but I don't think you can likely remember a string of random numbers and letters that is this long over the long term. You may think that you have it but if even one unknown digit is off then you will have a very difficult time accessing your funds. I would argue that if you were to make one small mistake, you would attempt to figure out your mistake, but would become frustrated and start to lose confidence in more and more over time.
I think a better solution would be to make a brain wallet with some phrase that you can easily remember while adding in a string of random numbers/letters at the end. I would suggest using the first x digits of the coinbase transaction of a block number that you can easily remember. Title: Re: finally memorized my private key :D Post by: Buffer Overflow on August 05, 2014, 08:27:09 AM I don't understand why people are implementing their own custom brainwallet ideas, it's just asking for trouble.
Just use armory. It's been designed for this sort of thing. Title: Re: finally memorized my private key :D Post by: oceans on August 05, 2014, 11:35:20 AM Pretty amazing that you managed to remember your key :) I have trouble memorizing way smaller numbers that these ones so I don't think there would ever be a chance I would memorize something this long.
