Details of the scheme are posted at: https://bitcointalk.org/index.php?topic=36195.0 It is intended as an interchange format, not specifically integrated with wallet encryption, and simple enough to be produced by the vanitygen program. Importing to the official bitcoin client using a method like the import/export patch would require the user to provide the password of the private key, in addition to the wallet password if the wallet is encrypted. Comments on the format are welcomed! As the proposed format is base-58, I would like to make a request to use one of the data classes as proposed by Pieter Wuille about a month ago: http://sourceforge.net/mailarchive/forum.php?thread_name=20110708092506.GA6641%40ulyssis.org&forum_name=bitcoin-development If this doesn't fit with the general bitcoin development agenda, that's OK too, but I would like to explore some possibility for a protected export format for private keys. Thanks, -Sam Revitch
