Software components for data protection, secure storage and transfer

Transfer files using FTP and FTP-over-SSL with your Java or Android application

SecureBlackbox product diagram

FTPSBlackbox (an integral part of SecureBlackbox) enables developers to quickly implement FTP and FTPS file transfers in their Java and Android apps.

The FTP / FTPS Java library includes client and server components implementing both FTP (RFC 959) and FTP-over-SSL (RFC 2228) protocols for unsecured and secure file transfers.


Both FTPS (FTP-over-SSL) and SFTP (SSH File Transfer Protocol) protocols enable secure file transfer operations including the abilities to create, upload, download and delete files and directories. However, FTPS and SFTP are two different protocols that require different FTP libraries to implement in your applications. A Java FTPS library implementing the FTPS protocol in Java is called FTPSBlackbox, while the SFTP protocol is implemented with a corresponding SFTP Java library, the SFTPBlackbox package.
