FTP/SSL for Java


Zehon FTP/SSL Features

Zehon FTP/SSL for Java is a versatile file-transfer component for Java language. It allows you to transfer files directly from your application using FTP/SSL, an extension of FTP which is fast becoming a standard for secure FTP. This protocol is also known as FTPS or FTP over TLS and is defined by RFC 4217. The name Secure FTP is used to refer to this protocol as well, although this can also mean SFTP, which is a different protocol that runs over SSH - we provide an SFTP component as well.

 

Secure your FTP transfers using TLS and SSL protocol

FTP/SSL enhances the standard FTP protocol by utilizing the well known and widely used TLS and SSL protocol. TLS 1.0 and its predecessor SSL 3.0 provide strong authentication, integrity and confidentiality on both the control and data channels. This is achieved by using RSA or DSA public key cryptography to authenticate the server (or even the client) and to negotiate the encryption method and symmetric keys to be used to encrypt your data. There are many FTP servers that support FTP/SSL (FTPS) and their number is growing constantly.

 

Upload from memory, download folders & more...

Upload data directly to your server without creating temporary disk files.  Transfer the whole folder using a single line of code. Open a remote file as a stream and work with it as if it was accessible locally. Monitor upload and download status and progress using custom events.
