Hello,

I?ve built openssh and I?m having some issues running it on my  

board. While running sshd it reports an error in libcrypto while trying to
read the host key. The host keys are generated under /etc/ssh.

I?m using:
openssh version 8.5p1
openssl version 1.1.1k
crpytodev-linux fabe5989a3d

Is there an issue using this combination of packages? These are the  

lastest versions in buildroot.

My config file (sshd_config) is only trying to load the host key for  

RSA, but I get the same error about libcrypto for ecdsa and ed25519.

Anyone see this issue as well? Any help is appreciated.  

You can try to run sshd with strace to get a clue about the failing  

syscall (in case this is the reason) in libcrypto....

Which hardware and which (hardware) crypto device?

Can you search for the corresponding 'open(...) = 4' which file the file
descriptor belongs (or belonged) to? Would suspect your crypto
hardware device '/dev/...' file...
 

I'm not seeing any line matching this.

Seems the kernel module cryptodev.ko needs some more kernel
options enabled...  

I was missing these two kernel options. I've enabled them and ran this again with cryptodev debug enabled. Not seeing any error about failing to load a module.
