Various Linux SCP Examples To Get You Started With Using Secure Copy

Posted by John Carl Villanueva on Mon, Jul 06, 2015 @ 10:37 PM

Overview

SCP (Secure Copy) is a quick, easy way to transfer files securely between two Linux machines. If you don't mind using the command line and all you want is a simple way to upload or download files on Linux, this series of SCP examples should be all you'll need to learn how to do it.

How To Set Up SSL Client Authentication on an HTTPS and FTPS Server

Posted by John Carl Villanueva on Fri, Jun 05, 2015 @ 11:32 PM

Overview

People who use SSL/TLS to secure their online transactions/file transfers are mostly only familiar with two of its security functions: 1. That it can encrypt data in transit and 2. That it can enable clients to authenticate the server. They're likely not making use of another feature that can greatly enhance SSL security even more - client certificate authentication.

If you've been following our posts, you know that client certificate authentication has been the subject of our discussion lately. However, we've never been able to talk about how to enable it on the server side. This quick post will be all about that.

How To Create A Client Certificate

Posted by John Carl Villanueva on Wed, Jun 03, 2015 @ 10:07 PM

Overview

In this post, we show you how to create a client certificate. Client certificates are the key pieces in client certificate authentication, a method you can use to augment your HTTPS, FTPS, or WebDAVs server's username-password login system. 

This is actually just one of three closely related posts that can help you take advantage of this less-known security feature of SSL/TLS. The other two posts are:

How To Import A Client Certificate To Firefox

Posted by John Carl Villanueva on Mon, Jun 01, 2015 @ 10:27 PM

Overview

Client certificate authentication is very suitable for highly-secure HTTPS connections. But for this type of authentication to work, the server must be configured for it and a client certificate must be loaded unto a client application. In this post, we'll focus on the client side. More specifically, we'll talk about how you can import a client certificate to Firefox.

What Is Client Certificate Authentication?

Posted by John Carl Villanueva on Sun, May 31, 2015 @ 09:54 AM

Overview

How do you strengthen a server's user authentication system? Well, one solution would be to add another. Most servers authenticate users through the usual username-password technique. If you can augment that with another method, you'll be able to make it more difficult for impostors to break in. For servers whose users connect through Web browsers, one option would be something called client certificate authentication. Let me explain what it is.

Meeting AES 256 Encryption Requirements For Data In Transit

Posted by John Carl Villanueva on Tue, May 19, 2015 @ 11:59 PM


Overview

Not many organizations require AES 256 encryption to secure their sensitive documents. But those who do might find this post quite useful. Here, we'll show you how to enable FTPS, SFTP, HTTPS, WebDAVS, OFTP, and AS2 file transfers with AES 256 bit encryption. Does that look like something you can use? Read on!

An Introduction To Stream Ciphers and Block Ciphers

Posted by John Carl Villanueva on Tue, May 12, 2015 @ 07:52 AM


Overview

Secure file transfer protocols like SFTP, FTPS, HTTPS, and WebDAVS encrypt data through symmetric key ciphers. These ciphers can be classified into two groups: stream ciphers and block ciphers. Today, we'll discuss what a stream cipher is and what a block cipher is. We'll also talk about the popular encryption algorithms that fall under each group.

What Is A Cipher?

Posted by John Carl Villanueva on Sun, Apr 26, 2015 @ 10:56 PM


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.

Symmetric vs Asymmetric Encryption

Posted by John Carl Villanueva on Sun, Mar 15, 2015 @ 02:35 AM

Overview

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? 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.

How To PGP Encrypt Every Single File Uploaded By A Particular User

Posted by John Carl Villanueva on Fri, Dec 26, 2014 @ 09:55 AM


Overview

Some guys in your organization may have to handle lots of sensitive information. Because there's always a good chance their files are going to contain confidential data, it would be best to ensure that every single file they upload to your server get utmost protection. On JSCAPE MFT Server, you can do that by applying OpenPGP encryption on all virtual paths owned by that user.
