unlocking an unspent vout with externally managed key

Wed, 20 Sep 2017 06:32:03 +0000

Hi Multichain folks,

How do you unlock an unspent output in an address with an externally managed key?

Also, if an output is locked, can it still be sent using createrawtransaction?

Thanks.

Alternative to unlocking an encrypted wallet

Tue, 29 Sep 2015 11:54:53 +0000

Sorry - I know that this is Q&A, but I can't find an appropriate place for feature requests, so here goes...

Unlocking the wallet for a period of time is one of the biggest security flaws with the bitcoin daemon. Once the wallet is unlocked then any process on an authorised machine can connect and issue send instructions until such stage as the wallet is locked again.

Just a thought, but how about appending the wallet password as an optional parameter to the JSON RPC calls that require an encrypted wallet to be unlocked. Assuming the implementation used SSL for RPC calls the password can be transmitted to the daemon securely and used to unlock it solely for that method call.
