 # Encrypting Files and Folders
 Encryption is an effective measure to protect sensitive data. This How-to card provides instructions for file and folder encryption on platforms commonly used by LCSB staff.

In this [link]({{ '/?access:passwords' | relative_url }}) we list  tools that can be used for password management. **Please make sure you have arrangements for password management before starting the encryption of data**.

 The Uni-LU HPC Team is planning to install [EncFS](https://en.wikipedia.org/wiki/EncFS) on the HPC clusters. EncFS allows for the creation of an encrypted volume (similar to a folder). EncFS provides transparent encryption, once you mount the encrypted volume, anything that goes into the volume will automatically be encrypted. Also, whenever you try to view or process a file in a mounted EncFS volume, it will be decrypted for you (behind the scenes) automatically.
 
-We will provide instructions for EncFS once it becomes available .
