Currently I am wondering whether it is possible to apply asymetric encryption of a directory in Linux.
I would like to achieve the following:
- Write log files to /var/log/secret
- Everything written to /var/log/secret is instantly encrypted by a public RSA key (or something similar)
The encryption programms I know, i.e. ecryptfs do not support asymetric encryption of files, at least as far as I know. (Correct me if I am wrong). Therefore I am asking here whether you know of any possibility to implement this.
Thanks in advance

There's a reason encryption programs don't do asymmetric encryption on the file system. It's extremely slow. Even SSL/TLS (arguably the best known implementation of public key crypto) only uses it for initial handshake and then switches to symmetric. – Rob H – 2011-03-02T16:24:08.190
Hmm, would it be possible for small amounts of data? Lets say about 200 MB a day??? – ftiaronsem – 2011-03-02T20:19:09.230
