Imagine that you are building a Java application to download files from an FTP server. How would you establish a connection and ensure the secure transmission of files from the server to your application?
- Employ the java.util.zip.ZipOutputStream and java.util.zip.ZipInputStream classes to compress and decompress files during transfer. Implement secure transmission using encryption libraries.
- Establish a connection using the java.io.BufferedReader and java.io.BufferedWriter classes. Ensure secure transmission through custom encryption and decryption logic.
- Establish an FTP connection using the org.apache.commons.net.ftp.FTPClient class, and enable FTPS (FTP over SSL/TLS) for secure file transfer.
- Use the java.net.Socket class to create a socket connection and implement custom encryption for secure transmission.
To establish a secure connection for downloading files from an FTP server in Java, you can use the org.apache.commons.net.ftp.FTPClient class. To ensure secure transmission, enable FTPS (FTP over SSL/TLS) in your FTP client configuration. This approach ensures that file transfers between your application and the FTP server are encrypted and secure.
