Hello,

I noticed that the v3.x Beta version of SolidExplorer finally offers slightly less ancient Key Exchange Algorithms compared to the v2.x version:

KexAlgorithms diffie-hellman-group-exchange-sha256,diffie-hellman-group-exchange-sha1,diffie-hellman-group14-sha1,diffie-hellman-group1-sha1,ecdh-sha2-nistp256,ecdh-sha2-nistp384,ecdh-sha2-nistp521,curve25519-sha256,curve25519-sha256@libssh.org

While curve25519-sha256,curve25519-sha256@libssh.org are welcome additions compared to v2.x, this list could still be expanded. The golden post-quantum standard nowadays is mlkem768x25519-sha256, and it'd be useful to offer also a fallback to sntrup761x25519-sha512 as well.

Above aside, it's also important to note that the set of Ciphers permitted by SolidExplorer is obsolete as well:

Ciphers aes256-ctr,aes192-ctr,aes128-ctr,blowfish-ctr,aes256-cbc,aes192-cbc,aes128-cbc,blowfish-cbc,3des-ctr,3des-cbc

Please add long-time standards like chacha20-poly1305@openssh.com and aes256-gcm@openssh.com.

The list of MACs is also ancient/obsolete:

MACs hmac-sha2-512,hmac-sha2-256,hmac-sha1,hmac-sha1-96,hmac-md5,hmac-md5-96

Please support hmac-sha2-512-etm@openssh.com
