Aladin Astronomy Software - Java Problem

You have two choices:

  • change the crypto-policies on your system, yes[1]
  • ask to and hope that Aladin folks deploy a more modern certificate

  1. for the security reasons: it doesn’t expose your system to external attacks, but it simply allow to accept less secure certificates signed with deprecated and weak algorithms. If you are concerned, the alternative you have is to not use sites and services that provides such certificates. ↩︎
