The Los Rios Community College District email system is an insecure communication medium. It is imperative and required by Los Rios Regulation R-8871, section 3.2.4 that high risk data not be sent in emails unencrypted, either in the email subject/body or as an attachment. If high risk data must be sent via email, the high risk data must be encrypted with 7-Zip or Adobe Acrobat Pro.

The password to unlock (decrypt) the encrypted attachment must be provided separately (e.g., by phone, in person, by stand-alone non-networked fax machine, or as a last resort via a second email that does not describe what it is). Below, are instructions on how to encrypt a document with 7-Zip and Adobe Acrobat Pro:
