Why would you like to use the CFB mode?

Because that's what the current (non-NSS) code does. I'd rather just
port, not change, the code.

Is the CFB mode used in your implementation of some standard?
Just curious.

The crypto support in NSS has been primarily driven by the needs
of the higher-level NSS libraries in -- libnss3.so (certs, etc.),
libssl3.so, and libsmime3.so.  Since SSL/TLS and S/MIME don't
need the CFB mode for block ciphers, we didn't implement it.
This is also why we haven't implement RSA PSS and RSA OAEP.

But people have started to use NSS only for crypto, so we
may need to start to invest more in this area.  I'd still like
to know what (protocol, standard, or proprietary system) you're
using the CFB mode for.
