RE: Bug 24755 - Decide which AES-CFB shift sizes to support

The only thing that I know that regularly uses AES-CFB is PGP.  I would be
totally happy to only have CFB-8 to start with and add other modes if people
request it.

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.
