AES-SIV in forward mode about cppcryptfs HOT 4 CLOSED

Callback of gocryptfs issue: rfjakob/gocryptfs#108

from cppcryptfs.

Thanks for the encouragement. Contributions would be welcome.

I'm sorry for the late reply.

I see that @rfjakob already responded to your gocryptfs issue.

I will try to keep up with enhancements to gocryptfs.

If gocryptfs adds a deterministic option for SIV forward mode, then it should be easy to implement it.

A writable reverse mode would be a lot more work but doable.

@rfjakob reminded me that gocryptfs is now using HKDF (derives separate keys for filenames and data) and Raw64 (base64 without the '=' padding chars) by default.

I just now added support for those features to cppcryptfs.

You might need to refresh your cppcryptfs source if you're having problems using filesystems created by the current version of gocryptfs.

Thank you for the reply! Do not worry about the latency, we can't be on top of github 24/7! I was out of the city for a seminar the past few days myself :)

Will certainly pull the latest commits and rebuild :)
