Can't connect to Ubuntu 22.04 server via SFTP plugin with pub key

[alexantr]

I'm using SFTP 2.90 and can't connect to Ubuntu 22.04 server with public key.
Same problem in WinSCP https://winscp.net/tracker/1952 was resolved in 5.20 beta.
Please add support rsa-sha2-256 and rsa-sha2-512 algorithms to SFTP plugin.

rsa-sha2-256 and rsa-sha2-512 are not supported by Libssh2 1.10 yet (their latest release), so I cannot add them even if I tried.

They are currently implementing it, but so far they only support the openssl backend:
https://github.com/libssh2/libssh2/issues/634

I wonder why Ubuntu doesn't support "ssh-ed25519" or "ecdsa-sha2-nistp256/384/521", they are all secure methods.

OK, I have installed Ubuntu 22.04 now and written the 2 missing functions myself. Please try this new beta:
https://www.totalcommander.ch/beta/sftpplug300b1.zip
Please note that the plugin itself is unchanged from 2.90, just the libssh2.dll has been updated!
The modified sources of the dll are here:
https://www.totalcommander.ch/beta/sftpplug300b1_libssh2-1.11.0_pre.zip

With these changes I can login to Ubuntu 22.04 with an RSA client certificate. Please try it!
