Unless the RFC changed AES 256 is supported in TLS 1.3 via TLS13-AES256-GCM-SHA384 Thanks, Jeff Holden, CISSP Chief Information Security Officer California Community Colleges Technology Center California Community Colleges Security Center On Wed, Nov 28, 2018 at 11:30 AM Ronald Loneker <rloneker () cse edu> wrote:
Good Afternoon All - Our Financial Aid office would like to have students and their parents, when e-mailing financial aid documents containing sensitive information, to comply with federal regulations saying the documents should be e-mailed with AES-256 encryption. 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
