Note: If a key size is undefined, the default key bit length size
used is 2048. A key with a zero length or blank key size field will
not be created.
When you delete a host key and recreate a new one, SSH client sessions will warn you
that the host key has changed for this particular IP address. You must then take one of
the following actions:
1.
Override the warning and accept the new Public Host Key and start a new con-
nection. This is the default. This option allows users to login using either method.
Whichever mode works is allowed for logging in. If the Public Key is not correct or
the Passphrase is not valid the user is then prompted for the login account pass-
word.
2.
Remove the old Host Public Key from their client system and accept the new
Host Public Key. This option simply skips public/private key authentication and
immediately prompts the user for password over a secure encrypted session
avoiding sending passwords in the clear.
3.
Load a public key into VelaSync. This public key must match the private key found
in the users account and be accessible to the SSH, SCP, or SFTP client program.
The user must then enter the Passphrase after authentication of the keys to
provide the second factor for 2-factor authentication.
Please consult your specific SSH client’s software’s documentation.
