A growing number of businesses are finding it imperative to get certain products out in the market FAST. To beat extremely tight deadlines, most of them employ IT systems to accelerate business processes. Whenever these processes require file exchanges across departments, cities, or continents, file transfer systems start to play a crucial role. And that role doesn't just involve moving files from point A to point B.

Overview

The strength of an encryption largely depends on two components: 1) the cipher and 2) the length of the key. We already discussed key lengths in an older post. So today, let's talk about the other component.

Overview

Digital signatures help enforce security during data transfers. They're mainly responsible for establishing authentication, data integrity, and non-repudiation. Today, we'll be talking about the basic concepts behind digital signatures, where they're used, how they work, and why they're always an integral part of highly secure file transfers.

Overview: Symmetric vs. Asymmetric Encryption

Secure file transfer protocols generally employ a combination of symmetric and asymmetric encryption to preserve the confidentiality of data while in transit. So why the need for two kinds of encryption? What is the difference between symmetric and asymmetric? In this post, we take a closer look at the main functions of symmetric and asymmetric encryption, their strengths, their weaknesses, and why we'd prefer having both.

JSCAPE is pleased to announce the release of updated versions of it's Secure FTP Factory (9.2), Secure iNet Factory (9.3) and SSH Factory (4.3) Java development libraries. These updates focus on performance and security improvements made to the SSH, SFTP and SCP classes in these libraries which include:

Overview

In today's data-driven world, the accuracy, integrity, speed, confidentiality, and availability of data matters a lot to businesses. That's why it's imperative for file transfer systems to be capable of meeting the highest standards in regards to those aforementioned qualities. In this post, we examine the typical SFTP server and point out what kind of benefits you'll get from it as a method for delivering business critical data.

Overview

What good is an encrypted data transfer if the information it protects still falls into the wrong hands? SFTP security is best known for its ability to encrypt data in transit. But while data-in-motion encryption can secure confidential information as it traverses the network, encryption can't prevent an impostor from carrying out the download himself. For that purpose, you'll want your users to authenticate with the correct password and SFTP key.

In this post, we'll talk about the role of SFTP keys (a.k.a. private keys) in the overall security of the SFTP protocol, how it works, where to use it, and other bits of information regarding this important element of SFTP.

Overview: SFTP Command Line

Although GUI SFTP file transfer clients are more intuitive to use, some people still prefer to use SFTP through the command line. That's understandable. If you're already familiar with all the commands you need, a command line interface can be so much faster and powerful than any GUI-based counterpart. In this post, we're going to introduce you to the SFTP command line and show you how it can be quite a handy tool as long as you're willing to roll up your sleeves and get dirty.

Overview

To support both regular and sensitive data transfers, businesses typically reinforce their FTP service with a secure file transfer protocol like SFTP. But while these secure network protocols do a good job in protecting data during transmission, data-in-motion security isn't the only thing trading partners require from a file transfer system.

Overview: How to Use an SFTP Client

In this tutorial, I'm going to show you how to use an SFTP client to connect with an SFTP server and then upload and download files with it. In addition, I will talk about host keys and how they are used to verify the server's identity. Finally, I will also demonstrate how to load up a private key and take advantage of public key authentication.
