The following new features and improvements were added to WS_FTP Server 2024.0 (9.0).

Updated SSH encryption settings

WS_FTP Server now supports ECDSA and EdDSA host keys and user keys, as well as additional ciphers, MACs and KEX algorithms. The ECDSA user public keys can be generated or imported but the EdDSA allows only importing public keys. For details of the supported ciphers, MACs and KEX algorithms, see Listener Encryption Settings (SSH).

Insecure ciphers, MACs, and KEX algorithms are not supported. Less secure ciphers, MACs, and KEX algorithms, such as diffie-hellman-group-exchange-sha256 and diffie-hellman-group14-sha256, are disabled by default on new and upgrade installations but can be enabled after upgrade if required.

To protect transactions against the Terrapin SSH vulnerability, all cbc ciphers should be disabled when using any encrypt-then-mac (-etm@openssh.com) MAC algorithms. Therefore, cbc ciphers are disabled by default. If a cbc cipher is enabled, -etm@openssh.com MAC algorithms are disabled on upgrade.

Note: Updates to the encryption settings resulted in the removal of support for the following host keys and MAC and KEX algorithms:
  • Host/User key
    • DSA host key
  • MAC
    • hmac-md5
    • hmac-md5-96
  • KEX
    • diffie-hellman-group1-sha1
  • Host Key Algorithms
    • ssh-dss
    • ssh-rsa - disabled by default but can be enabled.

Updated TLS support

WS_FTP Server 2024 introduces support for the TLS 1.3 protocol. This support makes the latest and most secure TLS standard available.

Note: SSL 3.0, TLS 1.0, and TLS 1.1 are no longer supported.
