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...

There are several different types of Bitcoin clients. The most secure are full nodes like Bitcoin Core, which will follow the rules of the network no matter what miners do. Even if every miner decided to create 1000 bitcoins per block, full nodes would stick to the rules and reject those blocks.

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?

I see, thus avoiding sending a "watching-only" wallet from offline to online computer?
