From Wikipedia, the free encyclopedia

Client-side encryption is the cryptographic technique of encrypting data before it is transmitted to a server in a computer network. Usually, encryption is performed with a key that is not known to the server. Consequently, the service provider is unable to decrypt the hosted data. In order to access the data, it must always be decrypted by the client. Client-side encryption allows for the creation of zero-knowledge applications whose providers cannot access the data its users have stored, thus offering a high level of privacy.
