To decrypt the Private Key in the Encrypted Vircurvault Bitcoin Wallet you are sent, use the Casascius Bitcoin Address Utility and do the following:
- Open the BtcAddress.exe file and select Tools > KeyDecrypter.
- Enter the Private Key found inside the Encrypted Vircurvault in the top field. Note: It will start with “6P”.
- Enter your original passphrase in the bottom field.
- Click Decrypt.
The utility will open up a new window with the actual Private Key for the Paper Wallet. You can view the key by double clicking the address in the interface. Your decrypted Private Key can be imported into a digital wallet, or online wallet of your choice at this point.
