Janus is a secure cryptocurrency wallet. For daemon based wallets they are using the core blockchain and database to store your keys. Standard encryption is used on these types of wallets and can be encrypted from within settings if your wallet is new or unencrypted.
For node based wallets like Janus Cypherium, your private keys are stored encrypted in a local database. This is default and they will never be stored unencrypted. Those keys never leave your computer and are never sent across the network. For encryption of your keys we use Advanced Encryption Standard AES-256.
Janus wallet is free to use and open source to copy and use as your own. We only depend on donations to fund future development and do not charge any transaction fees to use our wallets.
