A private key is a confidential alphanumeric code that grants access to a cryptocurrency wallet. It is used to sign transactions and prove ownership of digital assets.
Because possession of the private key equates to control over the funds, it is crucial to keep it secure and confidential. Loss or exposure of the private key can lead to irreversible loss of assets.
Private keys are generated using robust cryptographic algorithms and must be stored securely, often in offline or hardware wallets.
