Client-side encryption of stored emails is not currently supported.
Client-side encryption of stored emails (as notably offered by [[Wikipedia:protonmail|ProtonMail]]) is not currently supported. However, the benefits of such encryption are largely illusive. A malicious entity with access to the server could change the internals of the server to store a non-encrypted copy of all emails elsewhere. The only way to avoid this is with true end-to-end encryption (see PGP above).
 
 
=== Criticism of PGP and the limitations of email ===
 
PGP has been heavily criticized because it is cumbersome to use – and as a result, has seen very little adoption – and because it does not provide [[Wikipedia:Forward secrecy|forward secrecy]]. The limitations are inherent to email, which is based on protocols from the 1980s. It is unlikely that email will ever become a truly secure medium of communication. Those who need true cryptographic security combined with usability should opt for messaging apps like Signal.
 
 
== File encryption ==
 
[[ownCloud]] does not currently support client-side encryption. However, you can encrypt your own files locally on your PC. An easy way to do this is with [https://cryptomator.org/ Cryptomator]. Cryptomator allows you to encrypt a folder before it is uploaded to the cloud. A downside is that you won't be able to access your encrypted files in the ownCloud app for mobile devices. You can, however, use the Cryptomator app and configure it with Webdav to connect to ownCloud.
