# Private Keys

> Private Keys are cryptographic public / private key pairs that can be used for cryptocurrency needs or more generalized encryption. Turnkey securely holds all private key materials for you, but only you can access them.

The Private Key ID or any derived address can be used to create digital signatures. See [Signing](/api-reference/signing/overview) for more information
