StrongCoin
This is a browser-wallet where the key-information is stored in the browser and can be accessed via JavaScript.
Note - the service is not (yet) protected with SSL and the user could potentially become victim of a man-in-the-middle attack, particularly when using a wi-fi connection..
StrongCoin accounts are protected by a passphrase that is known only to the user and only an encrypted key for that password is stored with StrongCoin[1]. As such, if the passphrase is forgotten or lost, not even StrongCoin can help to recover the funds. The service does provide the ability to print paper backups of the keys which can be re-imported and when doing so no passphrase is required.
Interesting Features
- Import of private-keys in Mini private key format
- Printable "paper" backup of key-pairs
Fees
- StrongCoin adds 0.01 BTC per spend transaction.
