Client-side encryption refers to the practice of encrypting data before it is sent to a third party for storage or processing. In this setup, the client holds the encryption keys, ensuring that sensitive information remains private and secure.Typically, when a user interacts with a cryptocurrency application or service, their data is encrypted on their device before being transmitted. This means that even if an outsider gains access to the stored data, they cannot read it without the corresponding decryption keys.This approach enhances privacy, as service providers or third parties cannot access or view the encrypted data. Users retain full control of their information, reducing the risk of data breaches and unauthorized access. By keeping encryption keys on the client side, the security of sensitive information is significantly improved, making it a preferred method for those who prioritize confidentiality in their transactions and interactions.
