Description
Use sftp to establish a connection to a remote IPv4 SFTP server and enter SFTP client view.
When the client's authentication method is publickey, the client needs to get the local private key for
validation. In non-FIPS mode, as the publickey authentication uses RSA and DSA algorithms, you must
specify an algorithm (by specifying the identity-key keyword) in order to get the correct data for the local
private key.
The following matrix shows the default algorithms used in FIPS and non-FIPS modes when an SFTP client
establishes a connection to the SFTP server.
