AWS::Transfer::Connector SftpConfig

A structure that contains the parameters for an SFTP connector object.

Syntax

To declare this entity in your AWS CloudFormation template, use the following syntax:

JSON

{
  "TrustedHostKeys" : [ String, ... ],
  "UserSecretId" : String
}

YAML

  TrustedHostKeys: 
    - String
  UserSecretId: String

Properties

TrustedHostKeys

The public portion of the host key, or keys, that are used to identify the external server to which you are connecting. You can use the ssh-keyscan command against the SFTP server to retrieve the necessary key.

The three standard SSH public key format elements are <key type>, <body base64>, and an optional <comment>, with spaces between each element. Specify only the <key type> and <body base64>: do not enter the <comment> portion of the key.

For the trusted host key, AWS Transfer Family accepts RSA and ECDSA keys.

  • For RSA keys, the <key type> string is ssh-rsa.

  • For ECDSA keys, the <key type> string is either ecdsa-sha2-nistp256, ecdsa-sha2-nistp384, or ecdsa-sha2-nistp521, depending on the size of the key you generated.

Run this command to retrieve the SFTP server host key, where your SFTP server name is ftp.host.com.

ssh-keyscan ftp.host.com

This prints the public host key to standard output.

ftp.host.com ssh-rsa AAAAB3Nza...<long-string-for-public-key

Copy and paste this string into the TrustedHostKeys field for the create-connector command or into the Trusted host keys field in the console.
