Title:
  1024-bit signing keys should be deprecated

Status in Launchpad itself:
  New
Status in apt package in Ubuntu:
  Invalid
Status in gnupg2 package in Ubuntu:
  Confirmed

Bug description:
  1024-bit RSA was deprecated  years ago by NIST[1], Microsoft[2] and
  more recently by others[3].

  1024-bit signing keys are insufficient to guarantee the authenticity
  of software distributed from Launchpad.net including PPAs. There
  should be a mechanism to refuse signing keys below a minimum key
  length based on key type. 1024-bit signing keys should be deprecated
  and removed from Launchpad.net itself ASAP.  Future projects and PPAs
  should be disallowed from using 1024-bit signing keys.
