EnterpriseDT Security Blog

Our business is information security, and so we blog on a variety of topics in this area. We often comment on the security aspects of current affairs, as well as providing technical discussion on cryptography and related areas such as privacy. We are particularly interested in secure protocols such as SSL/TLS and SSH. Our flagship product is CompleteFTP, a Windows server supporting FTPS, SFTP, SCP and HTTPS, all of which are reliant on SSH and SSL/TLS.

All of CompleteFTP’s configuration data is stored in a SQL database called config.sdf. It can be found in the C:\ProgramData\Enterprise Distributed Technologies\Complete FTP folder. You […]

How to enable long filenames in CompleteFTP

With Windows 10 and Windows Server 2016, this restriction finally has a workaround (although it is not the default behavior yet). Here’s how to enable long filenames in CompleteFTP:

Requirements

  1. Windows 10 or Windows Server 2016

How secure is SFTP?

SFTP and SSH

SFTP is a network protocol for transferring files securely over a computer network. Its full name is the SSH File Transfer Protocol, and as it implies, SFTP is a set of commands that runs over another protocol known as SSH, or Secure Shell.

SSH is what provides SFTP with its security, and so to understand how secure SFTP is, it is necessary to examine how SSH works. SSH uses a layered architecture, […]
