Hello,We recently started using ownCloud which has an encryption-at-rest option. However, their encryption scheme increases file size by 34%. We need to have our files encrypted at rest so I was thinking that maybe LUKS was the better way to go. Can anyone tell me if we'll see the same kind of increases in file size? I ask because we're trying to plan on how much storage we should buy.
How large are the files you are creating?
Most "enclosures" uses a header and the header will increase the overall size of encrypted file.
LUKS for example uses a header that is 2MB.
If you want to encrypt individual files,why not go with gpg?,their header will increase the file size by only 41 bytes.
