I want to enable Transparent Data encryption (TDE) on MySQL. I don't mind if the entire db is encrypted (as opposed to a few columns or rows or tables). I am using this for a study, so I am looking for something that is open and free. I found zNcrypt but it's a commercial product. They are essentially using eCryptfs which is open-source, but couldn't find a way to rightly configure it for MySQL. Any pointers on using eCryptfs with MySQL or any other solution for enabling TDE with MySQL would be very helpful. Thanks!
I see this question is relatively old, but just in case:
eCryptfs can be considered a filesystem, so, you should just need to mount it, and then point your MySQL datadir to the mounted directory. The only drawback is that it doesn't seems to support O_DIRECT, but I don't think MySQL uses it, does it?
