Before your files can be restored, they have to be decrypted with your key. The method for decrypting your files and accessing your key depends on how you restore your files, as well as your security settings. This article describes the different options for restoring and decrypting files.
CrashPlan server: A Code42 server, or a server owned and maintained by your organization, depending on the configuration of your enterprise's Code42 environment.
When and where your backed up files are decrypted varies based on which restore method you choose. Refer to the table below for details.
|State of files stored at backup destination||Method of file transmission||How are files transmitted?||Where are files decrypted?|
|CrashPlan app||Encrypted||Internet, local network or direct connection 1||Communication channel secured with 128-bit AES encryption||Your computer|
|CrashPlan mobile app||Encrypted||Internet||Communication channel secured with 128-bit AES encryption||Your device|

1 Note: If you restore from a local backup destination, like an external hard drive, then files are not transmitted over a network. If you restore from another computer on your network, files are transmitted over your local network. If you restore from a remote friend's computer or from CrashPlan Central, files are transmitted over the Internet.
If you restore from the CrashPlan web app, your files are decrypted on CrashPlan's servers. If you don't want your decrypted files stored on CrashPlan's servers, choose one of the other restore methods: from the CrashPlan app, CrashPlan mobile app, or from a friend's computer.
