SSH parameters
This release updates Secure Shell (SSH) parameters. You can now configure the SSH
authentication-type, the SSH encryption-type, and the SSH key-exchange method, using the
following commands:
ssh authentication-type {[aead-aes-128-gcm-ssh] [aead-aes-256-gcm-ssh]
[hmac-sha1] [hmac-sha2-256]}
ssh encryption-type {[3des-cbc][aead-aes-128-gcm-ssh ][aead-aes-256-
gcm-ssh] [aes128-cbc][aes128-ctr][aes192-cbc][aes192-ctr][aes256-cbc]
[aes256-ctr][blowfish-cbc] [rijndael128-cbc][rijndael192-cbc]}
ssh key-exchange-method {[diffie-hellman-group1-sha1][diffie-hellman-
group14-sha1]}
If you want to delete all authentication, encryption, or key-exchange methods at once use the no
parameter before the main command: no ssh authentication-type, no ssh encryption-
type, no ssh key-exchange-method.

Enable SSH
To enable SSH, enable RSA or DSA authentication, or both using command ssh rsa-auth or
ssh dsa-auth.

Secure web server with TLS
This release introduces the Secure Web server with TLS feature which enhances communications
security by replacing the SSL 3.0 protocol with Mocana NanoSSL to secure the HTTP server using
the Transport Layer Security (TLS) cryptographic protocol.
TLS server generates a new self-signed certificate on boot and uses that by default. The self-signed
certificate is available in /.intflash/.cert/.ssl. You can choose to use an online or offline
CA signed certificate which will take precedence over the self-signed one.
