Cerberus FTP Server
SSH SFTP Public Key Authentication
Cerberus FTP Server Professional and Enterprise editions can perform public key authentication for SFTP connections. When using public key authentication, Cerberus will verify that the signature presented by an SFTP client matches the public key associated with that user.
Multiple SSH Keys Per Authenticated User
Flexible Authentication Settings
How it Works
The Cerberus FTP Server User Manager allows each user to be configured with a required authentication method. The authentication method can be set to require:
- A password only (the default)
- A public key only
- Both a password and a public key
There is also an option for selecting a public key file when the authentication method for a user is set to public key or password and public key authentication. The public key file can be in SSH format (as defined in RFC 4716), OpenSSH v2 format, or from a PEM or DER encoded certificate.
Process Support – Multiple SSH Keys per Authenticated User
A single user can authenticate with more than one different SSH client key. This allows interactive or automated processes that share a common username and sign-on from several different machines to enjoy the benefits of multi-factor authentication without the hassle of key replication and coordination.
