finally memorized my private key :D

[slaveforanunnak1]

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.

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..

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?

[haploid23]

Just hope you don't get Alzheimer later on. I would still make a backup anyways.

[herzmeister]

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.

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. ) Lf9z
Day2. then i wrote the next four on my hand. gWQn
Day3. All eight. Lf9z gWQn
Day4. All eight. Lf9z gWQn
Day5. ogid
day6. DA76
day7. ogid DA76
day8. ogid DA76
day9. MzPL
day10 6TsZ
day11 MzPL 6TsZ
day12 MzPL 6TsZ
day13 ZY36
day14 hWXM
day15 ZY36 hWXM
day16 ZY36 hWXM
day17 ssSz
day18 NydY
day19 ssSz NydY
day20 ssSz NydY
day21 XYB9 KB
day22 XYB9 KB

then I tried to associate the end of one block of 8 to the beginning of the new block of 8 so i could get the order correctly, you know, kinda like TCP sequencing.
after that i could say about 90% of it. 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. ( thanks snowboarding)

You should have converted it into a mnemonic of English words. Or started with diceware and sha256ed that to get a key pair.

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...

[jonald_fyookball]

I could memorize a private key in probably  20 minutes.

[Yakamoto]

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.

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.

[Watoshi-Dimobuto]

I think memorizing private key is not that hard. Currently my brain phonebook has currently 22 phone numbers its in on my brain for 2 years now. I will try to memorize mine, but how to find the private key where to look?

[nkocevar]

If you are just keeping them in cold storage, best thing to do is have 2 paper copies of your private key and then out them both in separate safe deposit boxes. At least that's my opinion

[lemfuture]

genius.

If you are talking about torture, it may be best not to even know a few digits of it. But then again with my idea they could just force you to open the safe deposit boxes.

Kind of ironic that all this effort could be compromised by hitting him on the head with a 5$ wrench isn't it?
