Data encryption options

Cloud Storage always encrypts your data on the server side, before it is written to disk, at no additional charge. Besides this standard, Google-managed behavior, there are additional ways to encrypt your data when using Cloud Storage. Below is a summary of the encryption options available to you:

  • Server-side encryption: encryption that occurs after Cloud Storage receives your data, but before the data is written to disk and stored.

  • Client-side encryption: encryption that occurs before data is sent to Cloud Storage. Such data arrives at Cloud Storage already encrypted but also undergoes server-side encryption.
