# `@d11k-ts/crypto`

The D11K CRYPTO package is a crypto package used by all `D11K` clients.

D11K-CRYPTO encrypts a master phrase to a keystore. This keystore can then be exported to other D11K wallets or stored securely.

Users can export their phrase and import them into other wallets since it is a BIP39 compatible phrase.
