Title: Brainwallet with Shamir's Secret Sharing Post by: Wary on November 24, 2013, 07:38:48 AM Is there such thing? To break a passphrase to several parts.
The closest thing I've found is http://weissjeffm.github.io/bitaddress.org/bitaddress.org.html on tab "Split Wallet". But there is no field to enter the passphrase to split. :( Anybody knows a SSS password-splitting java script?

From the changelog (Version: 0.88-beta (18 Apr, 2013)): Quote Fragmented Backup Scripts (Expert Only). Two new scripts added to “extras” directory: “frag_wallet.py” and “unfrag_wallet.py”. These scripts can be used to split your wallet into pieces/fragments using Shamir’s Secret Sharing. This is only available from the command line, but will be integrated into the application itself in the next release. The new interface will include restoring fragmented backups created with these scripts. There is currently a more recent version in testing, which might have better usability. I haven't tried it. Edit: Ah, you are looking for a brain wallet. Doubt Armory does that. Maybe it is useful anyway.

You might enjoy this though. http://www.moserware.com/2011/11/life-death-and-splitting-secrets.html Title: Re: Brainwallet with Shamir's Secret Sharing Post by: Wary on November 25, 2013, 09:19:06 AM Have you looked at Armory?
