title: Java SFTP client that takes private key as a string
body: <p>Apache Commons and JSch both require a private key file to set up an SFTP connection. The project I'm working on will be used to connect to multiple SFTP servers. Therefore, we do not hope to deploy multiple private key files, but rather keep these keys as strings in an encrypted config file. Is there an SFTP library that doesn't require a file object for private key?</p>
