| The list of paths to trusted SSH key files controls the public / private key authentication that SFTP allows for. This setting does not want you to enter in a 'trusted keys file', or a folder path, but rather the path to the actual key file itself. So '/files/keys/' is bad, while '/files/keys/ben.pub' would be OK. Separate multiple items with new lines. Most SSH key formats are supported. |
| The list of paths to trusted SSH key files controls the public / private key authentication that SFTP allows for. If set, we will assume the user will attempt [SSH public key based authentication|https://www.ssh.com/academy/ssh/public-key-authentication], if no password is supplied at login time. In real-life use case the client end generates the key pair, supplies server side \\ |
| the public key that the server admin will apply on their user account. Server side has no knowledge of the matching private key, that would be the end client's own secret.\\ |

| There is also a more generic way to use this field. If the key file has the exact name of the user logging in, you can instead reference the directory '/files/keys/'. In this case there would need to be a file named 'ben' in that directory. |

| !!Supported key file type and format:\\ |
| __The key file container__ must be plain text with __PEM__ encoded SSH public key in __SSHv2__, __openssh.com__ or __putty__ format. The older SSHv1 format is not supported.\\ |
| \\ |
| __Supported SSH key algorithms__ in CrushFTP v10 are __SSH2-RSA__, __DSA__ (obsolete), __ECDSA__ and __ED25519__. The older SSH1 RSA algorithm is not supported.\\ |
| \\ |
| __Key size:__ For RSA keys, the minimum size is 1024 bits and the default is 2048 bits . Generally, 2048 bits is considered sufficient, though these can be as large as 8192 bits (slow). DSA keys must be exactly 1024 bits as specified by FIPS 186-2. For ECDSA keys either 256, 384 or 521 bits. Ed25519 keys have a fixed length. |
