We have been using LiquidFiles for over five years now. Overall, we have been happy with it and users do not seem to have difficulty with its use. It is administered by my team and I. Originally the system was delivered to us as a virtual appliance and the initial setup and configuration, as well as ongoing maintenance, updating, and monitoring of system usage was and continues to be relatively simple. We've configured the system so that all of our students and staff can use the system both for sending and receiving secure e-mail and files. When it comes to training, we have a three-page help document. However, as far as I know, we have only had to provide this document to one individual throughout our years of use of LiquidFiles; the remainder of users were able to self-train using the system's built-in documentation and help resources. If you'd like a copy of our training document or would like to talk more about Chemeketa's experiences using LiquidFiles, please feel free to e-mail me directly.

For the folks using LiquidFiles, curious how it is going. Is it easy to use for both the end user and the recipient? We are thinking of implementing it to allow for secure upload of documents.

Since TLS 1.3 was released and is now in use in Chrome, the TLS 1.3 protocol uses only AES-128 encryption so we're considering asking our students and their parents, if e-mailing sensitive documents, to encrypt them with a yet to be decided encryption application at the AES-256 level and attach the encrypted file to the e-mail being sent to our Financial Aid office. We would provide links to easy to use, free encryption software and provide directions on how to download, install and use it. We are also considering adding this software to our computer lab images for those students who want to e-mail documents but don't have access to a computer at home. Right now, the other web browsers seem to be using TLS 1.2, currently operating at the AES-256 level, with Firefox and Safari saying they expect to move to TLS 1.3 in the near future at some point. I'm curious as to what other schools are doing, and whether they are putting any sort of language on their website saying that documents like this should be encrypted to prevent unauthorized access to the data. *Please note that I am not looking for vendor solicitations.* Ron Loneker, Jr. Director, IT Special Projects College of Saint Elizabeth Henderson Hall, Room 202C 2 Convent Road Morristown, NJ 07960 Phone: 973-290-4229 e-mail: rloneker () cse edu
