Certification refers to the confirmation of certain characteristics of an object, person, or organization. This confirmation is often, but not always, provided by some form of external review, education, assessment, or audit. Accreditation is a specific organization's process of certification. According to the National Council on Measurement in Education, a certification test is a credentialing test used to determine whether individuals are knowledgeable enough in a given occupational area to be labeled "competent to practice" in that area.

    Info Why the synology.com default certificate ?

    So why does this cert exist? Can it safely be deleted? Is it just a placeholder since DSM requires at least one certificate? On one machine in expires in several months. On another machine it expires in 2037. Why? Is this cert machine specific, or could I export/import it across machines...
