Hi, I think it is a good idea to support stronger algorithms. As a new hashing algorithm, you can also consider Argon2 algorithm, the winner of the Password hashing compettion (https://password-hashing.net/). The implementation is already available: https://github.com/p-h-c/phc-winner-argon2.

I already found a TODO in the code that ecryptfs should support more algorithms than just SHA512 * 65536. I tried brute forcing this, and got no further than about 20/s, but on FPGAs/GPUs this would be a lot faster. > > It should be easy enough to borrow code from OpenSSH, which uses bcrypt in their secure new private key file format (ssh-keygen -o; their old format is pretty weak (MD5 once, encrypt with AES 128)). > > Questions: > > 1) The v2 wrapped does not have a field to indicate which algorithm is used (like /etc/shadow (crypt API) has).
