Description Mark Watson 2014-02-20 21:41:23 UTC 
Presently, the document describes only CFB-8.

If we wish to support other values of the shift size, s, we need to either
(a) add s as an additional parameter to AesCfbParams
(b) defined separate algorithm names, e.g. "AES-CFB-8", "AES-CFB-128" etc.

In offline discussion with Ryan we have a preference for (b).

Of course it is also an option to leave this as CFB-8 only.
Comment 1 Mark Watson 2014-02-24 20:24:48 UTC 
Agreed on 2/24/14 call to rename AES-CFB-8 and support only this shift value.
