Topic: Use another bitcoin address as your password - page 2. (Read 4205 times)

Now we can tie our BTC to our testicles, thanks for the great info.

best ever 

Here's another hare brained scheme for you guys to consider:

- Take out your camera and take a picture.

- Make a hundred billion copies of that picture and stick it everywhere. In USB sticks, DVDs, memory cards. Throw them around the house. Make sure a few tiny memory cards end up behind the sofa like loose change. Even wear one as an amulet around your neck.

- Use the sha256sum of the picture as your password. Very easy to do on *nix


- And if you need multiple passwords just append a number:

Memorize a simple password in your head 1234BitcoinEater, then memorize the hashing procedure, e.g. SHA256(HEXTOBIN()) then use it as your password.

If you have multiple passwords you could combine multiple one way hashing algorithms and add 1 to the end of your memorized password, then every time you need a new one simply add 1 to it and hash the same way to get a completely different password.

Great idea, can't wait for the upcoming alt coin generator

...rather than use another bitcoin address , use a random altcoin address!

Heck , make your own alt coin just to make your own passwords!

When they say security through obscurity, this is what they should mean. Kinda hurt I was on the almost ignored list haha

Ps now that I've hopefully slowed down some thieves with this new idea, don't do it. But switching characters may help as he said. Or hash it eg 165 times

There are 2^160 public addresses.  So the thought of a hacker making a rainbow table is not possible.
A public address is not a bad password.  As long as you are generating it with truly random methods.

A password-password! Why didn't I think of that before! Going to patent this now!

That is as redundant as sha-256ing a sha256ed password. You just created exponentially more encryption collisions to breach your own security, not halved them. (As one might think would be the effect.)

If "DOG" is the password, but encrypted it is "CAT", and double-encrypted it is "FISH"...

Now "FISH" can be found by finding any collision that "DOG" has, which also results in "CAT", which will then result in "FISH". Plus, the collision of "PICKLE", "FROG", "MILKY", which also have matching results for "CAT" which results in "FISH", because they are a collision of a collision. (Plus they have their own large number of collisions for each one of those too.) Thus, exponential answers.

Same with just a simple password that is encrypted. It has collisions, so you can guess the password or the collision, and get in. As opposed to just having a password as an actual password, where there is only ever one solution. (Though, it would have to be a good password, which is larger than any "secure" hash-value. Poof, instant thievery stumped, they will be searching for collisions where collisions never exist.)

P.S. "Great minds think alike"... No one ever said they think correctly.

And to think, everyone has a huge dictionary of pre-found hashes, and possible collisions, sitting right on the bitcoin chain, and all the other alt-chains. Tons of "password results". And uber-computers finding more every day.

So when a wallet-address has a collision, both the original person, and the new person have access to the funds. Start creating tons of addresses, and HOPE there is a collision! Free BTC! No password needed. The network will validate the collision address, just as easily as the original address. Since, by formula, they result in the same answer.

I must say you are genius who came up with such a nice idea of securing password but I guess by sharing it on the forum you have made it less secure as anyone who visited your post shall be looking if a person has two bitcoins or not.

I use "1" as my password on everything... Easy to remember and no-one ever guesses it... they always start hacking at 4 letters/symbols or more...

Great, now I have to change all my passwords!

You'll never guess the one I use next! It's not "2"... don't even try it! I was born at night, but it wasn't last night... It's another number!

FTFY ;P

I don't think it is a good idea. How many BTC wallets are there? May be 2 million. If a hacker can use brute force method, using all these 2 million available passwords, then it can be easily cracked.

There's something missing here:  namely, context.
I don't see any mention in OP or the entire thread of exactly what you need this password for.
That would help me get my teeth into this idea.  For now, it's just airy speculation.  Let's have a real-world example, something specific.  Then let's examine the pros and cons.

And this is the exact reason why I don't put anybody on ignore, whether warranted or not, for you'll never know when they'll share a nugget. As far as I'm concern, it's a genius idea.

And, who's to say you have to use one of your own wallet addresses? And, you could simply generate X addresses solely for password purposes, never funding them.

EDIT: Upon reading the rest of the comments, I see that there may be some concern for such a practice. Surely, once a wallet address is generated, a character or two or three could be change so that your now new password can no longer be found anywhere on the internet.

For instance 13Lfcc8obgmBDGadoPHu3MSbN4sjSyWWoN (just copied and paste from BC) would become 31Lfcc80bgmBDGad0PHu3MSbN4sjSyWW0N.

Worst suggestion ever!

bitpop it's a good idea to choose a password.
Nonetheless security through obscurity is not secure enough
and considering you have to store the password somewhere anyway,
this doesn't increase security

I always thought it was a "word", meaning,  concatenation of characters from a given alphabet.

It's in the name: pass-word.
Why call it a password if it's not a word?

I use part of my vanity address 1234Ff3D19v5JPHfUXw9PBimQc9LGfa6iN. It's also my luggage combination.

Just in case it wasn't clear, I was being sarcastic. Please do not use the blockchain as your password notebook.
