Bitsign: Sign a message with a bitcoin key
In this example, I sign the string "Hello, World" with my key labeled 'mytestkey' in my wallet. As you can see, the command prompts for the passphrase, it is used only within the timeframe of the transaction and immediately forgotten.
./sign.js mytestkey "Hello, World"
Passphrase:
