Topic: Easy way to send transactions generated offline? (Read 824 times)
I see, thus avoiding sending a "watching-only" wallet from offline to online computer?
Exactly. It seems like it should be possible to set up online/offline Armory instances, generate the public and private keys with a separate utility, and import the private key into the offline instance and the public key into the online instance.
It's possible to do the same with Electrum also: https://en.bitcoin.it/wiki/Electrum#Offline_wallet
Thanks. Is it easy to verify that the "deseeded" wallet contains no private info?
Yeah.

Hi, does anyone know an easy way, that works currently, to send transactions that were generated offline? (Using, e.g., the https://www.strongcoin.com/downloads/offlineTransaction.zip tool.)
StrongCoin as well as other sites that I have consulted recommend using http://bitsend.rowit.co.uk/ to send such transactions, but that site seems to have been defunct for the last several days, at least.
Blockchain.info used to be usable in offline mode, but no longer, it seems (it won't let me go to Import/Export tab any more when offline).
I know I could use Armory, but that seems like a pretty substantial code-base that I would need to verify if I want to be certain that their watch-only wallet format contains no hidden private-key data (I'm guessing that that file itself is encrypted, which precludes direct inspection of the file itself).
I also know that I could use suitable commands to send a raw transaction through the Satoshi client, but I'm trying to avoid having to run a full node and keep up with the blockchain.
Any other suggestions? Thanks...
