I am a newbie in linux & would like to have some information on ecryptfs:
1. What is the best Combination of cipher and its respective key length to be used in ecryptfs? (eg. aes-32/blowfish-24,etc....)
2. In Power Off condition, how safe and robust ecryptfs is i.e. in power off scenario, is ecryptfs highly secure?
3. If power supply suddenly gets switched off, does it have an affect on the encrypted data being saved on hard disk?

Any help would be appreciated
