About

Generated keypairs can be easily printed and saved to digital files for long-term storage. This tool is security-focused. Funds are never entrusted to a third party. Private keys can be passphrase-protected and divided into parts that can be geographically separated so funds are not accessible at any one location. Recommendations are automatically provided to improve the security of the tool's environment. First, this tool generates keys only in your device's browser. Keys can be generated offline and are never shared with a third party by design. Second, private keys can be protected with a passphrase. The passphrase is required to decrypt the private keys in order to access funds. Third, private keys can be divided into parts that must be combined to access funds. For example, a Bitcoin key pair can be divided into 3 parts where 2 parts must be combined to recover the private key. These parts can be geographically separated to prevent access at any one location.
