I created a ethereum wallet ages ago. However, I noticed when I open the ethereum wallet it does not prompt for a passphrase like alethone. Does this mean my keystore is not encrypted?
You only need to enter your passphrase when you want to transfer some ethers from your accounts / addresses.
Your encrypted keys will be stored in the following directories with one individual file for each account:
- Mac: ~/Library/Ethereum/keystore
- Linux: ~/.ethereum/keystore
- Windows: %APPDATA%/Ethereum/keystore
