[Owncloud] Cloud Storage Backends and File Encryption

[al at ila5.info]

Hello,

I had the chance to read a good article recapping some recent 
developments, and highlighting that one can use cloud storage accounts 
as a back-end into the OC file-sharing system. [0]  That is a neat 
development, but I was curious how that will work with the current state 
of file encryption available in OwnCloud.  Is it possible to use OC as 
middle-ware of sorts (excuse the bad terminology) to have the files 
encrypted to the cloud storage providers in question?

In a slightly unrelated note, I moved away from implementing my own OC 
instance and completely relying on that because of what I read about the 
file encryption algorithm used in the then current and stable branch.  
Out of curiosity, will or have the developers moved away from Blowfish 
in ECB mode?  I know it is a performance versus security issue, and that 
if I am storing stuff on OC, especially with the cloud back-end, I 
should be the last to talk, but that blog post made me have serious 
doubts about relying on OC solely as my file-store online and generally 
avoid cloud file-stores.  However, I see this as a kind of on the cheap, 
pseudo-host-proofed system so I can have secure control of files with a 
back-end more robust or larger than what I can have on the webserver I 
run OC from.

Thanks for the software, in any event.  I used it for a few weeks and 
thought it was great.

Best,
_AJS
