(PowerBuilder) AWS Transfer for SFTP (Amazon S3)

Once you've setup your AWS Transfer for SFTP in the AWS Console, interacting with it is no different than any other SSH/SFTP server. AWS will provide a private key in PEM format. It is used for authentication (instead of a password).

For more information, see https://docs.aws.amazon.com/transfer/latest/userguide/getting-started-use-the-service.html
