While our Security Statement mentions that the users are responsible for the protection of the authentication means and all actions performed under their profile, some clients would prefer even stronger security included into Memsource. They would like to be able to use encrypted MXLIFF files that could be opened only using the credentials.

Current behavior:

It's not possible to encrypt MXLIFF files. 

Workaround: 

Use any archival tool (like WinRAR) to password protect the MXLIFF files once you are done working.

Requested behavior: 

It's possible to download encrypted MXLIFF files.
