I am fine with this bump. In fact, I think we need to bump up the line
length limit even further, such that 4096-bit SSH keys will fit even
when they're base64- and then hex-encoded. I think they'd be at around
11 KB, so let's set the limit at 16 KiB (0x4000).
Yes, this double-encoding is weird, and it might be gone eventually.
As to inclusion in jumbo, I think we need to include Dhiru's patches in
a separate jumbo patch release, not along with lots of other changes.
I think Dhiru's additions are important enough that they need more
attention than they'd receive now (if rolled into -jumbo-5).
As an option, we may make the LINE_BUFFER_SIZE bump to 0x4000 now (in
-jumbo-5), which will allow for the "plugin" functionality to work for a
new revision of Dhiru's SSH cracker.
Thanks,
Alexander
