          Can you use cryptodev with ssl_engine in squid at the same time?

              armv8crypto is more like aesni for ARM CPUs. It's not safeXcel.

              When you run openssl with an engine selected it will use software for algorithms not supported by the 'engine'.

              The cryptodev framework can only be used by kernel space code. devcrypto existed to allow it to be used by userspace but is much slower and, as I understand it, not maintained which is why it stopped working.

              You should use -elapsed with openssl speed to see the actual time taken and not just CPU time. Othewise, when an actual hardware engine is used, you see very small times.

              If you're using DCO in OpenVPN you should not use devcrypto. DCO will use whatever is registered by the cryptodev framework and that should be safexcel.

              I will say there's a bunch of confusion here. Still. As I understand it the devcrypto part hasn't worked as I expected since FreeBSD11, so 2.4.X.
              Let me re-dig into it....

                How would you access it with openssl, I have DOC enabled but it does not recognize this as a useable engine?

                Side note, In 23.05.01 devcrypto does work and look at the noticeable differences:
                Check out 64bytes, 1024bytes, and 8192bytes.

                Please can you also research what is the normal block that use is in use.

                The 16384 bytes lags behind safexcel but the 64bytes,1024bytes and 8129bytes have a positive difference.

                Now running this test does reflect a use of the safexcel chip so it is accessed seen here also the counters increment during the test.

                Screenshot 2025-03-05 at 11.18.47.png
                without safexcel the advantages favor 16 bytes, 256bytes, and 16384bytes tests.

                  Both those tests are using some crypto off-loading. You can see because without using the -elapsed switch the time recorded shows CPU time during the 3s of the test and it's far lower than 3s. That also means the resulting Bps numbers are meaningless because the time taken is wrong.

                  That's interesting though because I don't see it in 25.03-beta. What version are you seeing those numbers in? 23.05.1?

                      @stephenw10 does 25.03 reflect increments on use of the chip in your system?

                        You mean in the interrupts shown by vmstat? They do, but not for aes-gcm. Which is what I'm digging into.

                          @stephenw10 thank you. Yes on the vmstat.I was thinking about adapting the OpenSSL.conf file to add the SafeXcel but I don’t know how, I am sure it is just adding the chip. I seem to remember I could change openvpn to bsd/safexcel on the hardware offload a couple months ago.

                          Side Note: There is also a way to use offloading with the directive ssl_engine on my favorite Squid package I have learned, that is amazing.

                          Per Squid support..

                          • If your Squid is built for libssl 3.0 or later, you may be able to configure /etc/ssl/openssl.cnf default provider to be the one you want. Such that Squid does not have to do anything for it to work.

                          I expect all the details relating to how devcrypto does its thing to be configured in /etc/ssl/openssl.cnf.

                          You may find this discussion from the OpenSSL community helpful:

                          Again same thing it accepts the directive but the vmstat counters do not increase.

                          Another note:

                          I also use .eli in fstab

                          # Device		Mountpoint	FStype	Options		Dump	Pass#
/dev/msdosfs/EFISYS	/boot/efi	msdosfs	rw,noatime,noauto	0	0
/dev/msdosfs/DTBFAT0	/boot/msdos	msdosfs	rw,noatime,noauto	0	0
/dev/gpt/swapUSB.eli		none	swap	sw		0	0

                          This .eli use with FreeBSD encrypts the swap and it does work when looking at logs.

                          Weird right this does increase vmstat when it is used. Again that would not block out everything because I also disabled it to test and it still did not normalize the system.

                            @stephenw10 any update on this? Maybe a change in openssl.conf ? I don’t know I am wondering where to add that cipher, as it is supported.

                              It's unlikely to work with the userspace devcrypto device. And even if it did you should not use it because it's so slow as to be worthless. Especially since armv8crypto was added.

                              But it should work for in-kernel crypto functions and appears not to be. Still digging...

                                  @stephenw10 Does use of .eli in the fstab file cause this? It should be able to do both right?

                                    I would expect that to be kernel level crypto, yes. But I've never checked specifically.

                                      Any updates on that kernel crypto functions?

                                          @stephenw10 I think it has to do with fstab use or .eli for swap, but even if I turned off .eli it still does not work.

                                            @stephenw10 Any word, if you need a copy of my config that is no problem.
