encryption routines

Where could I find some encryption routines that will work well with 4.25?
I am thinking about using 128-bit keys.


Thanks,

There is an ssh that compiles, although there is a bug that disallows

hangups from sshd. My /usr/lib has libssl and libcrypto, which I think
got there from that compile.

Depending on where you’re located (I see “.ca” – good) there’s the
AES/Rijndael encryption engine. It’s 128/192/256 bit, which “should”
be good enough for a while… :slight_smile: :slight_smile:

Go to www.nist.gov; I think that’s where the AES standard is stored
these days… It compiles on an 8-bit processor, so Q4 should have
no problems with it, and it’s fast.

I’ll check them out. I’m in Carleton Place jsut outside of Ottawa. Why
does the .ca matter? Can these not be used outside of Canada?

Historically, strong crypto had been subject to US export regulations.
After all, not just anyone is smart enough to figure out FTP :slight_smile:
I’m not sure what the current status is… That said, Rijndael,
as you can no doubt guess by the name, was developed outside the US.

I’ve also noticed that OpenBSD has a rijndael package that looks like
it encrypts/decrypts files. Of course, the main trick is generating a
256 bit key. There are some interesting RFCs on this subject (RFC2898
is a good one). Using a dictionary of 32768 words would require
17 randomly chosen words to be used as the password :-0

It’s also one of various ESP encryption algorithms used by IPsec.

I can remember when the original IBM PC came out, it was restricted by
the US government from being exported to any comunist block country.

If, even then, the original IBM PC was dangerous to give someone an edge
over the US, then what chance do we really have over terrorists today?
Today, they not only have computers, they also have cell phones!. If
they start using fax machines next, then we’re really up the creek!
