I just need a user-friendly way to sweep bitcoins from a offline paper wallet onto the Blockchain, without having to expose your private key, whilst you are online. People can screen grab the private key or they can use key capturing or clipboard highjacking in Malware to steal your private key. ^grrrrrr^

Give us a offline method to scan the QR code for the private key and then to copy & paste that onto a application, linked to the Bitcoin address you want to sweep it to and then encrypt that before you go online. The moment you go online the app connects to the Blockchain and it decrypts the information and sweep the key.

The source code should be OpenSource and posted on Github with a signed message from the developer. No logs must be kept or information redirected.

Can this be done?
