Brainwallet.org Poetry

[keatonatron]

Hi all,

I've been playing around with the converters at brainwallet.org--pretty cool.

I'm curious about the "poetry" function. I've seen this format used with other services as well as a way to save a secret key that can be used to recover an account, etc.

What I can't find is a technical explanation of how the conversion works. Does anyone know? And is the idea behind it simply that it's easier to avoid typos when typing actual words?

Thanks

From the source:

Code:

/*
    mnemonic.js : Converts between 4-byte aligned strings and a human-readable
    sequence of words. Uses 1626 common words taken from wikipedia article:
    http://en.wiktionary.org/wiki/Wiktionary:Frequency_lists/Contemporary_poetry
    Originally written in python special for Electrum (lightweight Bitcoin client).
    This version has been reimplemented in javascript and placed in public domain.
*/

So it converts every 4 characters to three words from that list.

Aha! The only place I didn't think to look 

Very interesting. This would be an easier way to type in private keys from a paper wallet, but I think it should be standardized or else the word list might change and render all your data useless. (Easy fix--print both the key and the 'easy to type' real word version)

The current wordlist and function is here -> http://pastebin.com/4HfuabMb

We could make it a standard right now

I think it's already a de-facto standard. We're using it on http://carbonwallet.com/
