Topic: [Bounty - Claimed] Vanity address split-key generator software (Read 22793 times)

[19:10] can I get the public key of a new address locally, using bitcoin-qt
[19:11] <@gmaxwell> ProfMac: open the console, run validateaddress on it.
[19:19] gmaxwell: thanks, that worked.
[19:40] I submitted the public key to https://vanitypool.appspot.com/newWork and it complains that it is compressed.
[19:42] <@gmaxwell> ProfMac: tell the vanitypool people to fix their crap. Generating vanity addresses w/ compressed keys is _faster_ than uncompressed.
[19:43] lol.  I will.
