New Features

[email protected] Key Exchange

The key exchange method [email protected] is now available if the Bouncy Castle library is available.

This uses a post-quantum key encapsulation method (KEM) to make key exchange future-proof against quantum attacks. More information can be found in IETF Memo Secure Shell (SSH) Key Exchange Method Using Hybrid Streamlined NTRU Prime sntrup761 and X25519 with SHA-512: sntrup761x25519-sha512.

Behavioral changes and enhancements

GH-318 Handle cascaded proxy jumps

Proxy jumps can be configured via host configuration entries in two ways. First, proxies can be chained directly by specifiying several proxies in one ProxyJump directive:

Host target
Hostname somewhere.example.org
User some_user
IdentityFile ~/.ssh/some_id
ProxyJump jumphost2, jumphost1
Host jumphost1
Hostname [email protected]
User jumphost1_user
</tr></table>
