[-- Attachment #1 --] Hi: I want to create encrypted memory filesystems for backup, and selective data destruction: If I have data from different users say, each user's backup will be stored as different encrypted file systems. Then I can selectively destroy data from one user by throwing away the key. Now, how do I estimate the actual available space on an encrypted partition? Say, I need to backup 100MB - how big an mfs do I need to create in order that the encrypted file system will be 100MB? Secondly: Which of the two supported crypto file systems is recommended: ELI or BDE? PHK writes in the manpage of BDE that no audit of the code have been made, but no such warning appears on ELI. Which is strongest/fastest/most efficient/reliable?
