Hi all,

I have some questions about SSH. 

1. The device generates two keys (server and host). What are the public key and private key?

2. Can an understandable key be downloaded from a device and used by PuTTY?

3. Does RSA support encryption of more than 2018 characters?

4. Does the phone support Ed 25519?

Thank you in advance.

Hi Sprout,

Here's my opinion. I hope it can help you.

1. Usually, we use the command 'rsa local-key-pair create' to create keys on devices. The keys in the new key pair are named device name_Server and device name_Host. After being encrypted by AES256, the local RSA private key is saved to the host key and server key files in the system NOR FLASH.

   Device name_Server is the public key

   Device name_Host is the private key

2.  No. due to security reasons, we don't support to do it. And we think there is no way to do it.

3.  The key ranges from 512 to 4096.  It is 2048 bits by default

4. No, we only support PEM/OpenSSH/DER encryption format.
